Best Cold Weather Long Johns for Late Season Hunting & Hard Water Fishing

Publisher: Keenan Crowe 02.17.21

When winter arrives, most people return home and begin their annual hibernation for the rest of the season. However, if you grew up hunting and fishing, you probably know that this time of year offers many good hunting and fishing opportunities – if you can stand the cold. With the end-of-season hunt upon us and the reports of hard water starting to come in, we’ve listed the best cold-water slips to find the right gear for your winter adventures.

We’ve been looking for high-quality, field-tested thermal underwear sets for men and women that will serve you well, whether you’re swinging over the fence for the last time at the end of the season, sitting on the ice in a freezing cold fishing hut, or just doing your best to stay warm when the temperature drops below your comfort zone. If Mother Nature has taught us anything, it’s that winter can be totally unpredictable, especially in areas that are considered warm year-round. Lie down and stay warm, my friends.


1. Carhartt Power Medium Weight Thermal Underlay Pants

A familiar name that will keep you warm.

A solid mid-weight base layer to add to your wardrobe at a very affordable price. And because it is made by Carhartt, you can be sure that you are getting a durable product that will last season after season. I regularly use a medium base layer when hunting, or alone or occasionally when it’s really cold I wear a medium layer under my heavier clothing. Trust me, you’ll be glad you have a few diapers to put on instead of too few!

Pro/waffle knit retains warmth – Quick-drying action eliminates sweat and fights odor – Durable, flexible knit technology for easy movement.

Imported/Exported – made of polyester

Underline/Big long underwear layered for cold weather

2. Carhartt Men’s Strength Heavy Heat Pant Base Layer

For a really deep freezer

When the mercury drops below freezing, these heavier long garments from Carhartt are perfect for the layering strategy suggested above. The thick fabric retains warmth and has durable flexibility that moves with you, as well as quick-drying technology that wicks away perspiration.

Pro/poly wool blend regulates temperature – Quick-drying, wicks away perspiration and fights odor – Strategically placed seams for maximum comfort and less friction.

Consumer / A little thin for a heavy base layer

Bottom Line/Best for light activities in very cold weather

3. Merino Wool LAPASA Thermo Long John Set

Total protection against the cold

Merino wool is a great fabric. Speaking of base layers, I suggest starting with a layer of merino wool directly on your skin.

Merino wool specializes in maintaining body temperature stability and does so in a very interesting way. When it’s cold outside, the natural undulations and curves of the fibres trap air and insulate you. When it’s hot outside, it quickly wicks sweat away from your skin, helping you stay cool and dry.

Recently I started packing my layers this way too, and I’ll never go without merino wool again!

Excellent insulation and warmth when the temperature drops – Made to be breathable so you don’t have to worry about overheating in it.

4. MEETWEE Winter Base Layer for ladies

Specific cut for women

For women who live in the woods, this basic set of layers includes heavy thermal top and bottom layers. Made from 92% polyester and 8% elastane, these long jerseys are made with Double Seamless technology with premium thermal properties, while the extra thermal inner fabric retains extra warmth.

Advantages / Comfortable – Super warm – Ultra soft

Requires light weight – Requires extra layers – Runs slightly less, according to reviews.

In short, for cold and mild weather, this is an excellent option.

5. J JINPEI Heated underwear for men and women

Turn down the volume and stay hotter than ever.

If you’re like me, you’ve probably been waiting months for winter and ice fishing. Being from Michigan, ice fishing is something I look forward to all year. I love going out on the ice surrounded by the beauty of winter, and catching nice sea bass for dinner. Of course, as with most things, you have to earn your loot, which often means spending hours on a frozen lake – Brr!

But don’t worry, we’re here to help!

If you’re expecting harsh conditions or can never stay warm outside for any reason, consider this heated base layer. The shirt and pants are rechargeable and can work for 3.5-6 hours without being charged for 4-5 hours. They heat up quickly at the push of a button and have three different temperature settings.

It’s a real hit in the icehouse!

Benefits / Comfort – Machine washable – Keeps you warm for hours

Consumers/arms a little stiff/bulky

With the underline/heated pinion, you can reduce the total number of layers.

Fitting of long underwear

When choosing the best size for your long underwear, there are a few things to keep in mind. Your stove should fit snugly, i.e. tight enough so that there is no gap between the fabric and the skin. This allows cold air to seep in. However, thermal underwear does not need to be tucked in. Your skin must be able to breathe and the water vapour must leave your body without returning to your skin, otherwise you will quickly freeze. Remember, the next layer of clothing doesn’t have to be so cozy, it gives those couples a place to go.

Choosing the best fabric

Here are some thoughts on the best textile materials for thermal underwear. As a rule, synthetic materials are a better base layer. One of the most commonly used synthetic fabrics is polyester, followed by nylon, polypropylene and viscose. You’ll usually find a blend of these fabrics plus spandex, which doesn’t have much thermal properties but adds a lot of comfort to the fabrics it’s blended with.

Merino wool is being used more and more. Merino wool is a natural fibre that comes from merino sheep. It is finer and softer than regular wool, making it easy to wear on the skin. Because it is a natural fiber, it keeps you warm and is breathable, so you can wear it to all kinds of activities. This is what we use ourselves and we highly recommend it.

What is the best way to stay warm?

Start with a thermal layer of underwear, followed by another layer, usually fleece. Get a warm jacket to protect you from the wind and you’re good to go. Don’t forget your hat, your gloves and especially your feet!

Can I wear too many clothes in cold weather?

Yes! You need to find the right amount of clothing for your activity level. The worst thing that can happen when it’s cold is sweating! If you sweat and can’t get rid of that moisture, you lose your body temperature much faster.
