I'm 6' 155lbs and normally wear a Medium (39-42) but ordered this in a Large. It's a close fitting but not compression shirt that is next to skin like a good base layer should be.Only complaint is the mock neck. It's a bit tight and somewhat impractical. I feel the shirt would be a lot more versatile if the mock neck was reduced to a regular shirt neck. ### ⭐⭐⭐⭐⭐ GO GO *by J***0 on Reviewed in the United States on March 14, 2018* Good product. Hugs the body and feels abundantly full featured. This Mock neck fit has a relaxing feel and keeps the warmth in from the neck down. The quality has to be experienced and before you know it you'll just GO with it. I tried many others and searched to the far reaches of the Apparel world to come to this brand and felt like I finally reached the correct destination with the GO offerings.Overall, I am pleased with the thickness and softness of the material as it feels like you are getting what you pay for. ### ⭐⭐⭐⭐⭐ Snug *by G***Y on Reviewed in the United States on February 18, 2019* The fit is snug, the collar fits against the neck giving no space for cold air to blow in from some gusty winds we had here lately. I got a medium and the arms have about 1/2 to 1 inch spare, as for the length my fear of it being too short was way off the mark. I can pull it down over my hips and I stand 6 feet tall. So you won't have to worry about it riding up at the wrong moment. --- ## 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.hr/products/54773108-go-athletic-apparel-mens-long-sleeve-thermal-underwear-shirt-cold](https://www.desertcart.hr/products/54773108-go-athletic-apparel-mens-long-sleeve-thermal-underwear-shirt-cold) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-07-06*
