The Best Thermal Underwear – Overview


 

Duofold Men’s Midweight Double-Layer Thermal Pant

The Duofold Men’s Midweight Double-Layer Thermal Pant is a best-seller with outstanding customer reviews on Amazon. This popular choice in male thermal underwear is a mid-weight, full-length style featuring a double-layer construction. The outer layer of the pant is made of 65% Cotton, 25% Merino Wool, and 10% Nylon. The inside layer is 100% cotton. This special double-layer fabric traps body heat effectively, keeping you warm in cold weather conditions.

Besides superb insulation, the Duofold Men’s Midweight Double-Layer Thermal Pant also scores top marks on comfort. The midweight pants are constructed with chafe-resistant flatlock seams, preventing skin irritation and friction. Furthermore, the pants are completely tagless, avoiding possible irritation from clothing labels. 

Machine-washable

The Duofold Men’s Midweight Double-Layer Thermal Pant is machine-washable, which is also a pro. Do note that this style is not moisture-wicking. Though the cotton inner lining should keep you dry, the breathability of the 2-ply fabric is a tad limited. If wicking is a priority for you, consider the Duofold Men’s Wicking Thermal Pant instead. This style is quite similar to the Midweight Double-Layer Thermal Pants but does not come with the cotton inner layer – making it more moisture-wicking and breathable. 

Tip: Like this style but want even more protection against the extreme cold? The Duofold Midweight Double-Layer Thermal Pant is also available in a Heavy-Weight, Expedition model: the warmest thermal pants in the brand’s collection. 

Pro

  • Affordable
  • Contains merino wool
  • Full 100% cotton inner ining
  • Double-layer fabric traps body-heat
  • Chafe-resistant flatlock seams
  • Tagless

Con

  • Not the most breatheable
  • Not moisture-wicking
  • Not recommended for extreme cold

 

Thermajohn Men’s Ultra Soft Thermal Underwear Long Johns Set

Sale
Thermajohn Men's Ultra Soft Thermal Underwear Long Johns Set with Fleece Lined (X-Small, Grey)
  • Mens thermal underwear is a lightweight thermal set of both a thermal top and bottom made of a poly-spandex material that will wick away moisture to keep you dry with no sticky or clammy feeling so...
If you’re looking for budget-friendly thermal underwear, the Thermajohn Men’s Ultra Soft Thermal Underwear Long Johns Set is pretty much as good as it gets. This affordable 2-piece set includes both a thermal top and thermal long johns, which makes it a great value buy. 

This Men’s thermal underwear set is made of lightweight, poly-spandex material. These synthetic fibers have many perks. Firstly, the fabric is moisture-wicking, keeping you dry and comfy on your adventures. Secondly, the fabric offers smart odor control, as it can absorb odor-causing enzymes – keeping you smelling fresh, longer. 

The Thermajohn Men’s Ultra Soft Thermal Underwear Long Johns Set has a snug, second-skin fit, which makes it ideal for layering with other outdoor clothing. The stretchy fit also ensures maximum mobility and means the fabric won’t constrict your movements during any outdoor activities. The long johns in the set are also tagless, preventing skin irritation. 

Great size range and color options

The Thermajohn Men’s Ultra Soft Thermal Underwear Long Johns Set is available in sizes XS to 4XL, meaning there’s a fit for nearly every hiker. Additionally, the set comes in 6 colors, allowing you to mix and match it with your existing outdoor apparel.

According to Amazon reviews, the Thermajohn Men’s Ultra Soft Thermal Underwear Long Johns Set is a lot of bang for your buck. Reviewers mention the set is warm and comfy. Do note that some consumers report sizing to run a bit on the small side. Therefore, if you want a slightly looser fit instead of a snug fit, considering sizing up. Also be aware that though this set is great value-for-money, it’s not the most durable or high-quality thermal underwear on the market, meaning it may wear and tear quicker than other products on this list. That said, for the budget-friendly price listed, we reckon you can’t go wrong. 

Pro

  • Budget-friendly
  • Excellent value-for-money
  • Includes both pants and a long-sleeve shirt
  • Great for lounging
  • Soft and comfy
  • Odor-control fabric
  • Moisture-wicking
  • Tagless
  • Machine-washable

Con

  • Only synthetic fiber, no wool
  • Not the warmest thermal set
  • No mention of flatlock seams
  • Not the highest-quality standard

 

Carhartt Men’s Base Force Heavyweight Thermal Base Layer Pant

Carhartt Men's Force Heavyweight Thermal Base Layer Pant, Navy Heather, Large
  • Poly-wool blend regulates temperature, fast dry wicks away sweat and fights odor
If you’re looking for the warmest pair of thermal pants the Base Force Heavy-Weight Pant by Carhartt could be your toasty match. This heavyweight thermal underwear is designed to cope with extreme cold weather and below-freezing temperatures. The poly-wool blend of the pants helps regulate body temperature and heat retention, keeping you comfy warm without overheating. 

The Base Force Heavyweight Thermal Base Layer Bottom by Carhartt can keep you warm, dry, and odor-free – even during high-intensity outdoor activities. The pants are made of a special blend of 80% Polyester and 20% Wool, and various state-of-the-art techniques. For example, the thermal pants are constructed using Force FastDry® technology, which means the fabric is moisture-wicking and fast-drying. 

Additionally, the fabric of these thermal pants features Anti-Odor properties, which ensures the fibers are less likely to absorb unwanted odors. Furthermore, the pants also come with Carhartt’s patented Stain Breaker® technology, which makes them able to resist dirt and grime, leaving your pants relatively stain-free. 

Premium comfort and quality

Carhartt has got the comfort level of these pants exactly right, thanks to its Rugged Flex® stretch technology. This gives the pants a stretchy, second-skin fit without constricting movement. Plus, the silhouette of the pants features strategic seam placement to reduce chafing and skin irritation. The Base Force Heavyweight Thermal Base Layer Bottom also features smooth, flat-lock seams, a contoured front panel with fly supports, and a key-split elastic waistband with concealed stitching: adding to its overall comfort. 

If you’re looking for thermal underwear for moderately cold days and lounging, this pair of pants may be slightly too warm or heavy-weight. However, if you’re looking for a premium pair of thermal pants that you can wear all winter long, and even use as a base layer for snowboarding, this product has got you – and your chilly legs – firmly covered! 

Also good to know: the Carhartt also sells a matching Base Force Heavyweight Thermal Base Layer Top, which is ideal for those looking for a full thermal underwear set. 

Pro

  • Great value-for-money
  • Contains 20% wool
  • Second-skin fit and fast-drying
  • Designed for extreme cold
  • Can handle below-zero temperatures
  • Stain Breaker, anti-grime technology
  • Anti-Odor properties
  • Rugged Flex technology for a full range of motion
  • Flatlock seams
  • Machine-washable
  • Key-split elastic waistband

Con

  • Not the cheapest
  • Can be a bit too heavyweight for mild weather usage
  • Not the most breatheable

 

Icebreaker Merino Anatomica Zone Long Boxers 

If you don’t mind spending a bit more to secure yourself of a high-quality, top-notch choice in thermal underwear, then consider the Icebreaker Merino Men’s Anatomica Zone Long Boxers. This extra-long version of the best-selling Anatomic Boxers by Icebreaker feature special zoned ventilation to keep you cool and dry, longer – without compromising on toasty insulation. Furthermore, these extra-long boxers are made of Icebreaker’s patented Cool-Lite fabric, making them superbly moisture-wicking and quick-drying. 

The Anatomica Zone Long Boxers by Icebreaker feature the same fantastic fit and comfort as the regular Anataomic briefs, with the bonus of extra ventilation. This lightweight, flexible, and breathable pair of boxers are made of jersey Cool-Lite fabric. This fabric features corespun fibers: which are nylon threads wrapped in merino wool. The combination of nylon and merino creates a second-skin softness and fit, which makes this the ideal hiking base layer. The fabric of these thermal pants also contains lycra, for added stretch and mobility. 

Superb breathability

To further promote its breathability, Icebreaker added panels of corespun eyelet mesh in key areas of the boxers. These clever mesh panels promote airflow where it matters most, keeping you dry and fresh – even on high-intensity outdoor adventures.

The Icebreaker Merino Men’s Anatomica Zone Long Boxers offer great anti-chafing comfort. The pant’s gusseted and streamlined design ensures a full range of motion, without the constricting or squeezing your most sensitive areas. These nylon and merino wool boxers also come with a comfy elastic waistband and flatlock seams throughout. This flatlock seam construction further prevents chafing and the risk of skin irritation.

Also good to know: The moisture-wicking, high-quality Icebreaker Merino Men’s Anatomica Zone Long Boxers are machine-washable for quick clean-up. 

Pro

  • Special zoned ventilation
  • Excellent breathability 
  • Cool-lite fabric helps you keep your cool
  • Second-skin fit 
  • Great as base-layer for hiking
  • Panels of corespun mesh 
  • Anti-chafing construction
  • Flatlock seams
  • Machine-washable

Con

  • Pricey
  • Not a full-length pants
  • Not recommended for extreme cold

 

Smartwool Men’s Merino 150 Base Layer Pants

Another best-selling choice in thermal underwear is the Smartwool Men’s Merino 150 Base Layer. These thermal bottoms are made of high-quality merino wool, known for its natural ability to wick moisture and excellent odor-resistant properties. The Smartwool Men’s Merino 150 Base Layer Boxer Briefs also feature targeted ventilation: keeping you dry and comfortable where it matters most.

The Smartwool Men’s Merino 150 Base Layer boxer briefs are made of a quality blend of 87% merino wool and 13% nylon. The merino wool ensures breathability and wicks sweat away from your nether regions. The nylon makes the briefs flexible and form-fitting. These thermal pants by Smartwool also feature an interlocking fit, which helps with the regulation of your body temperature and heat retention. The waistband of the boxers is also covered in soft merino wool for further comfort.

Flatlock seams to prevent chafing 

The Smartwool Men’s Merino 150 Base Layer has a flatlock seam construction to minimize chafing and skin irritation when worn as a base layer. These merino wool pants are also machine-washable (warm water on a gentle cycle) and can be tumble dried on a low setting. That said, to keep these pants in prime condition, we’d advise you to handwash them and letting the pants air-dry – as this reduces the risk of shrinkage. 

According to Amazon reviews, the Smartwool Merino 150 Base Layer Thermal Pants are a great investment for your outdoor comfort on cold weather days. The pants score highly on quality, comfort, and insulation. Granted, they are not the cheapest choice in thermal underwear, but for the price listed, we think they still offer great value-for-money. Because the pant’s its high-quality construction and merino wool softness makes them a worthwhile indulgence. 

Pro

  • Contains 87% merino wool
  • Excellent breathability 
  • Natural moisture-wicking properties
  • Waistband also covered in merino
  • Interlocking fit for temperature regulation
  • Snug, second-skin fit 
  • Great as base-layer for hiking
  • Flatlock seams
  • Machine-washable

Con

  • Not the cheapest
  • Not a full-length pants
  • Machine-washable can cause shrinkage

 


 

Verdict

So, which of the thermal pants in this overview do we rate as our top pick? Well, that depends a lot on where and when you plan to wear them, plus how much you’re willing to spend. Each product has its specific appeal, which means they could all be ‘the best thermal pants’ based on different buying factors…

For example, if you’re looking for a moderately warm, affordable pair of pants that can be worn for both hiking and lounging, the budget-friendly Thermajohn Men’s Ultra Soft Thermal Underwear Long Johns Set could be your ‘best match’. However, if you plan to venture out in extreme cold conditions, and need maximum protection from your base layer, premium options like the Carhartt Men’s Base Force Heavyweight Thermal Base Layer Pant and Icebreaker Merino Anatomica Zone Long Boxers are much more suited.

Or perhaps you’re looking for thermal underwear that sits somewhere in-between moderate warm and extremely warm: in this case, the Duofold Men’s Midweight Double-Layer Thermal Pant could be a toasty match. This double-layer pair of pants will keep you warm on cold weather days, but simultaneously won’t cause you to instantly overheat on fair weather days.

Another great alternative is the Smartwool Men’s Merino 150 Base Layer Pants, which combines the insulation and breathability of merino wool with the comfy stretch of nylon: resulting in second-skin fit thermal underwear that is super comfortable – and functional – as a base layer.

This style is available in both a Heavyweight and a Midweight variety, allowing you to choose your level on insulation based on your expected hiking conditions. The sleek midweight Base Force pants are ideal for wearing as a base-layer, whilst the heavy-duty, heavy-weight pants are ideal for keeping you warm even on the coldest, sub-zero days. 

Quick-drying, odor-resistant, and moisture-wicking

There are various reasons why we prefer this style. Firstly, it’s made by a trusted brand in outdoor gear: which is always a plus. Secondly, the pants are packed with innovative technologies and techniques. These include a special odor-fighting technology, a moisture-wicking construction, a stain-fighting technology, a quick-drying technology, and a special flex construction to ensure a full range of motion during your outdoor activities. We also give the material of the pants a thumbs up. The heavyweight pants are made of 81% Polyester and 19% Wool fabric, which is comfy, insulating, durable, and (a big pro for us) machine-washable. The midweight variety is made of waffle knit polyester, which is just as comfortable though slightly less insulation – great for fairer cold weather days…  Furthermore, both styles of these thermal pants come with flatlock seams to prevent chafing and a comfy elastic waistband for a snug fit. 

For the price listed, that’s a whole lot of value for money. The Carhartt Men’s Base Force Thermal Base Layer Pant isn’t the cheapest thermal underwear on the market, but it’s still surprisingly affordable when you consider its quality standard and comfort. Whether you prefer a midweight of heavyweight pants: the Base Force by Carhartt is a solid investment to your outdoor wardrobe.

 

 


The Best Thermal Shirt

Looking for a top to pair with your Best Thermal Pants? Then consider the North Face HyperLayer FC Long Sleeve Crew Neck: one of our favorite long-sleeved base layers on the market. Granted, it’s not the cheapest shirt on the market, but we think it offers maximum bang for your buck since it is suitable for year-round wear. 

The North Face HyperLayer FC Long Sleeve Crew Neck is insulated enough to keep you warm in cold weather conditions, but also breatheable enough to wear on warmer, sunny days. Plus, it’s fabric offers UPF-30 sun protection, meaning it also keeps you safe and shielded from harmful UV-rays when worn as a sun blocker. Made of quality materials, such as special quick-drying synthetic fabric, the North Face HyperLayer FC Long Sleeve Crew Neck is the perfect choice to compliment any of the thermal pants listed in this overview!

Hiking Socks Merino Wool Full Cushion Kakuetta Trail Size Medium US 4-10
  • MADE IN THE USA - (GREY) (MEDIUM) US SHOE SIZE 4 - 10 - Men's and Women's Warm Premium Quality Merino Wool Sourced Here in the USA.
Another must-have piece of thermal clothing is a pair of socks. The best thermal socks keep your feet warm, toasty and protected against the elements – without compromising on comfort or breathability. One of our favorite pairs is the Kakuetta Trail Merino Cold Weather Hiking Socks Set.

These high-quality socks are made of 100% Merino Wool, which means they are an all-natural choice to keep your feet warm and dry in cold weather conditions. Merino wool has natural moisture-wicking and odor-resistant properties, keeping your feet not just warm, but also relatively odorless and fresh. Well, we can’t guarantee the fresh part, but Merino wool is less prone to ‘soaking up’ odors like other fabrics such as cotton. Furthermore, when you accidentally step in cold water, merino wool socks don’t instantly lose their insulating properties – as they can still keep your feet warm even when moderately wet!
