MEETYOOMen's Thermal Underwear Set Sport Long Johns Base Layer

Great quality! Wore these to snowboarding on 0*F in Utah, it was snow and windy in the mountains and had no issues, they are comfortable stay dry and keep you warm without the need of too many layers over them. Highly recommend!!! I’m 6’ 205 lbs and ordered “L” they fit perfectly fine!

I love these , they keep you nice and toasty , and they fit perfectly not bulky , great product , I recommend these long underwear.

Lightweight, cool feel, stretchy, elastic waist, good fit overall, moves with you, not bulky.

I bought two sets of these. One was size Large and they are perfect. The warmth and comfort exceeded my expectations and I am very pleased with the product. However, I gave the item 4 stars as the size Small that I ordered at the same time for my 11 yr old son was way too big. The difference in size is barely noticeable, and they are two sizes apart. He can't wear them yet, but they are such good quality I will just save them for him to grow into instead of returning them.

I got these for my son for several backpacking trips he was doing, including the Appalachian Trail. Some of the nights were quite cold, and this helped keep him warm. They are very good quality and I feel like they're durable enough that they should last him for years. The only thing I wish was different is the sizes in the set-- my son in 13 yo and 6'3" but very thin. Having to purchase a L/XL set just to get the length we needed was our only option. The shirt was therefore way too loose for him and the pants were still a smidge too short. We couldn't have gone smaller or the length of the pants legs and the sleeves would have been too short. It would be nice to have an option to mix and match sizes in the sets for those that have similar fit issues. Otherwise, I am very pleased with the quality and functionality of this product.

I wear them with bike shorts and make them usable for colder times.

Order a smaller size, they come larger than you think

Okay
