Duofold Men's Lightweight Thermatrix Performance Thermal Shirt

I'm about 6' 165 with a slim athletic build, and I ordered a Medium. I would say it's just big enough for me with little room to spare. It's very form fitting and almost a little tight (not uncomfortable but close). The sleeves are long enough which is nice. The shirt itself is a little bit stretchy, it will sit a little high on my waist line unless I pull it down a bit. In my opinion for ~$17 this is a great base layer which seems like it does a good job keeping me warm. If your build is any bigger than me or you like a little extra room in your shirts I would consider a large.

I bought this on super sale in size Small. I am 165 lbs and 5'9" and it was way to tight. I wear a Large top in Duofold and a Medium in the pants. That being said, Duofold is hands down the best thermal underwear. I live in Alaska and use it daily- the most comfortable, best construction, longest lasting, best fit you can buy.

I really like this thermal, with one BIG caveat. I hate that the cuffs and lower sleeves are so small and minimally stretchable, that I can't pull the sleeves up near my elbows. That's a deal breaker for me. The shirt fit nicely, looks great, and works well, but when I get warm I need to be able to pull up the sleeves a ways.

I bought this shirt about a year ago. I've used it enough that I recently purchased a second. I primarily use it for running. I will run in this shirt without any additional layers down to about 40 degrees and it does a good job of keeping me warm and wicking sweat. It fits snug enough that it could be used as a base layer, but is also thick enough that it can be worn on its own. I live in Minnesota and intend to run through the winter. I plan on using these shirts as a base layer with a windbreaker over them (and maybe throwing on an insulating layer on really cold days). In general, if you are looking for an affordable, durable, and warm base layer for running or other physical activity, I would recommend this product. I'm 5'10, 150lbs and a medium fits great. The sleeves are a tad long, but it isn't problematic.

I'm a woman, 5'8," about 160 pounds, with relatively long arms. This fits me perfectly in a medium. Just wore it outside in 50 degrees for a long walk (with the Craft Women's Storm Tights, size large) with a light sweatshirt over it, very comfortable, warm, but not too warm. It was nice not to have to wear gloves. This will be perfect in the spring under a short-sleeved bicycle jersey for biking to work.

It's perfect, except for one flaw, it doesn't feel amazing against my skin. It's something you'd forget in 30 seconds after putting it on, but it's just a weird mesh fabric that isn't particularly soft. Not itchy or anything, just not super comfy. Oh well. Love the thumb holes and long sleeves. Perfect for cycling and running.

Arms are very long on these, they are constantly covering my hands, and the arms are uncomfortably bunched up when I push them back. The seams are also very uncomfortable- feels like sandpaper.

Great for layering plus it has thumb holes for added hand warmth.

muy buen producto y tela

My boyfriend loves this as a layering piece for work (he works outdoors) - says it is one of his favourites. Sizing fit perfect, bought a medium (he is 6 ft and 160 lbs).

Excellent fit ! very light & idle for packing. Yet to try in cold weather but really like the style and love the color ;)
