  • cozy comfort and reliable fit
Size: Large Color: Midweight-crew Neck-black
The CL convallaria Long Johns Thermal Underwear for Men has truly won me over! Initially skeptical, I was pleasantly surprised by its performance and quality. First and foremost, the sizing is spot-on – it fits true to size, which is a huge relief when ordering online. This set proved my initial skepticism wrong from the get-go. The craftsmanship is evident; the seams are well-sewn, ensuring durability for frequent use. The material struck the perfect balance for me. It's thin enough to comfortably fit under clothing without adding bulk, yet the quality remains excellent. The fleece lining adds a cozy touch without causing overheating, keeping you comfortably warm in cooler conditions without feeling too hot or restricted. The comfort and functionality of this thermal base layer impressed me so much that I ended up purchasing another set. Having a backup for when the first set is in the wash speaks volumes about how much I rely on and enjoy wearing this product. Overall, CL convallaria's Long Johns Thermal Underwear has become a staple in my wardrobe. It's a reliable, well-made base layer that perfectly balances warmth, comfort, and fit. If you're in search of quality thermal wear that performs as promised, this set is a worthwhile investment. Its ability to keep you snug without feeling bulky or overheated makes it a standout choice for colder days or as a versatile layering option. ... show more

  • Warm inside, but runs small, so order up 2 sizes if you want it slightly loose.
Size: Large Color: Midweight-crew Neck-black
Got these for a Christmas gift for my future son in law to wear on our upcoming trip to Montana. They feel thick and are nice and warm but they run small and had to be exchanged before the holidays. I personally, tried the large on before mailing them back. I’m 5’5” 120 lbs wearing the men's large, it’s big on me, but not enormous. I will say they are super comfortable loose! For comparison the gray shirt laying on my clean wood floor, underneath this black large is a large lounge wear shirt and it’s way bigger than this large thermal shirt. I’m exchanging for the next larger size and even wonder if I should go up 2 sizes?? UPDATE: I sent the large back, my daughter said get him an extra large, but I think I should have gotten him a 2xl. He said the xl fit fine but it looks tight. The inside lining is very soft. They are made well but the shoulders seems to run narrow. Jake is wearing the XL shirt and the pants are under the white/teal/purple sweat pants. He said the pants fit larger than the top. The set is bought together. I suggest ordering one size bigger if you want a TIGHT fit and 2 sizes larger for a loose fit. ... show more

Size: XX-Large Color: Midweight-crew Neck-black

  • Suprisingly warm
Size: Medium Color: Midweight-crew Neck-black
Size: At 5'10" and 180lbs, I normally wear Large clothing but based on my previous purchases, Amazon suggested Medium. I am glad I did not go by my usual size or the sizing chart in the description. Medium fits me just right, nice and snug. Good length, correct size around hips, waist and chest. Material: These long johns are very stretchy. And I mean it in the full sense of the word. Trying to pull the pants up over an ankle, you might stretch them to your neck. So grab the lower portion of the pants and pull them up over the ankle before proceeding with the top half. Same with sleeves. The elasticity is what keeps the long johns nice and snug and warm. The fleece lining is barely noticeable and thin but it is present. Thermal properties: Upon opening the package, I was surprised at the thin fabric. Definitely thinner than I expected for something that needs to keep the heat in my body on cold days/nights. I wore these long johns on very cold days (50F/10C) which is very very cold to us Texans. I even rode my motorcycle with these under my clothing. I was pleasantly surprised at their ability to keep me warm. I am not sure how they would do in actual freezing conditions so I will update this review once I have more data on that. ... show more
