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: Best Base Layer on the Market (not for Dad bods) - For everyone concerned with the size let me clear it up. I am 5ft 8 185 and the large (m100) for me perfectly! These long underwear are meant and should fit very tightly, like a wet suit. They also create warmth by you moving around. Thats how they are designed. I wear them under a cross country racing suit on extremely cold -10 to -20f and after the first mile I am toasty warm. They may feel cold when you first go outside but that’s ok start moving! They are also NOT designed for a “dad bod” . So if that’s your body type I would suggest a thicker and looser long underwear. If you are a x-ski racer, alpine racer, winter runner, fat biker or winter hiker I would highly recommend these long underwear. I live in MN where winter temps can be brutal and these are my go to base layer every time. ## Features - FLEECELINING & ACTIVE PERFORMANCE - Made of Premium Silky Soft Fleece Lining, Fleece material provides Ideal warmth Performance for Indoor & Outdoor Activities, Running and Hiking, Excellent Active Wear for Sports and Movement, Light weight and Enhanced Durability, Individually Packed Well for Protection - DRY & WICKING PERFORMANCE - Made of Fine fabric for Optimized Quick Dry & Moisture Wicking Performance, Can be worn all day long in Fresh Condition, Excellent Breathability to provide Optimized Ventilation and Air Circulation - 4 WAY STRETCH SPAN & FLATLOCK STITCHING - 4 Way Stretch Span allow you Great freedom of movement, Compression Fit to keep your Body Looking Slimmer, Suitable for Sports and Outdoor Activities, Flatlock stitching for Friction Free to eliminate Annoying itching - ORIGINAL FITEXTREME PERFORMANCE CLOTHING - FITEXTREME is officially registered Trade mark (Reg.

It wicks moisture as expected and keeps me feeling warm and dry while skiing. I normally buy thermal underwear to fit snug. I believe it works better that way. I purchased top and bottom in the extra large (XL). The top fits just the way I like it. It is long enough to cover my waist and some of my butt. The bottoms are the interesting part. The legs have extra material to cover my ankles but the top including the waist band seems short on material. In other words I have to pull them up into my crotch so the waist band reaches my waist. It's not uncomfortable but they did ride down some during skiing. The material in the waist area does seem equal to that of the legs. Hard to describe and by the way, the labels are in Chinese. I wasn't sure how to wash them but I assumed washing and line drying to be the best practice. I will buy them again but perhaps an XXL in the pants. ## Frequently Bought Together - FITEXTREME MAXHEAT Mens Thermal Underwear Long Johns Set with Fleece Lined - At The Buzzer Thermal Underwear Set for Men - Runhit Mens Thermal Underwear Set：Fleece Lined Long Johns for Men Thermal Shirts and Pants Base Layer Cold Weather Thermals --- ## 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.tw/products/22643194-mens-set](https://www.desertcart.tw/products/22643194-mens-set) --- *Product available on Desertcart Taiwan* *Store origin: TW* *Last updated: 2026-09-28*
