I am getting another pair now. Im 5"10, 170lbs, so pretty average size. Medium fits me perfectly. They are bit snug (which i want for a base layer) and very comfortable. The neck/collar is a little big, but no different than some of the v-neck style shirts today. The exterior has a spandex/lyra feel while the inside has a microfeecy kind of feel. They feel a bit thicker than a regular base layer and seem to be pretty warm. Will write an update after my ski trip and getting to use them in the wild, but I am pretty impressed thus far! 01-31-20 02-23-20 Returned from my ski trip. These are great! I got a 2nd pair after my previous post. These are warm and comfy and layer well. It was -11 for several days and I was fine with these and thin/waterproof shell pants on my bottom half. For my top half, I layered with a light performance jersey and light wind breaker with an outer shell. I never felt cold. I wore these as my base layer for 2 days of active skiing and they didnt stink after removal. No issues with stitching or quality thus far and i have washed them now a few times. These seem like a great base layer for a wide range of winter temps! Review: Warm but Runs Small - Extremely warm and comfortable—perfect for my trip to Alaska. Note that it runs small, so I recommend ordering one size up for the best fit.

Note that it runs small, so I recommend ordering one size up for the best fit. High-quality material and well-made, keeps you cozy in freezing temperatures ### ⭐⭐⭐⭐ Sizing difference makes a real good set worse *by I***N on January 30, 2019* I am a 6'1 220 lb guy and i ordered a Large based on the waist measurements. The bottom of the set is wonderful! The material is stretchy and soft and it seems to keep heat pretty well, but when in a warm environment it doesnt run too hot. They also fit really well.I would def get a Large bottom of this set again. My issue is the top. The neckline is weird, it seems to go down my back more than i would like. I am fine with how low it is but it seems cut weird. The sleeves are really small too. They ride up on my arms a lot. The chest is pretty tight and the shoulders are real tight. The material is soft and comfortable though, and i could see myself wearing it if the fit works. I will try to order the set seperately next time. and getting a Tesla also to compare ## Frequently Bought Together - FITEXTREME MAXHEAT Mens Thermal Underwear Long Johns Set with Fleece Lined - ALPIDEX Functional Wear Thermal Underwear Men Breathable Quick Drying Warm Base Layer Mens Cold Weather Set Long Johns --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pt/products/34942054-mens-thermal-set](https://www.desertcart.pt/products/34942054-mens-thermal-set) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-04-23*
