LAPASA Men 100% Merino Wool Shirt Base Layer Lightweight Midweight Thermal Top Long Sleeve Hunting Undershirt Warm Long John

It kept my body warm while I slept outside in 20 degree weather. Of course, I did also have a sweater on, but I survived a really cold night in which my body was covered in frost. So I would definitely consider this a great quality shirt.

Definitely want to get more. The value compared to a “high end” Track Smith merino wool is not even close. I find this much higher value based on what you get for the cost. Would recommend.

Merino wool, soft, lightweight and warm. Ideal for layering on a cold day. Worth the money!

I purchased this for a backpacking trip and it worked great for a mid-weight shirt.

Get this one. Bought MEDIUM. Me: 5'10", 185. 41" chest. Shirt size 16.5x35". Sleeves plenty long, and I cuff 1". Perfect snug (but not tight) fit. Non itchy Merino wool.

Did not like that waist doubles its width during the 1st wearing. Not the 1st washing but the 1st wearing. I own 7 other brand name wool³/wool blend⁴ tops and none of them have stretched even after multiple wearing and washing. Will not buy this brand again.

Great fitting shirt that works as a good starting layer when layering clothes to stay warm or wear alone when temperatures allow. Does not itch or irritate or at least hasn’t for me. Would recommend

I purchased this shirt because I've had good luck with their products in the past, and the trend continued. Pictures attached for reference. I am 6'1" 185lbs and I purchased a medium. The sizing and fit were as expected. The sleeve length reached my wrists, and the shirt length went about 2 or 3 inches past my belt line. The shirt isn't super tight like a compression shirt, but you aren't swimming in it either. The fabric is VERY soft to the touch, and feels great against the skin. It has some give/stretch to it, but will maintain it's form. The collar fits nice, not too tight against the neck. I found the shirt to be nice and warm, and wear it around the house instead of a light sweatshirt. I'd highly recommend for anyone looking for a long sleeve top.
