MERIWOOL Mens Base Layer 100% Merino Wool Heavyweight 400g Thermal Shirt for Men

This is the base layer I have been looking for for years. Super thick, very warm. Absolutely brilliant

Good value, you'll struggle to find merino at a similar price point, just wish the weight was a little heavier

super quality, suggest always to hang dry to extend the life of any wool garment

I just love this shirt (have it on now). The quality is outstanding and it is super warm. If you don't know what 400g merino wool is like .. this thing is closer to a sweater than a shirt. It is THICK. I have three of these an basically wear them all winter because I am cold natured. This shirt totally is not a base layer. I still wear a base layer of 100g merino wool under this shirt. A 100g merino wool base layer, this bad boy, and a 650 lightweight down jacket get me through winter most of the time. I do swap out the jacket for a serious down puffer when it gets REALLY cold and I am going to be outside. Above freezing, the shirt and a light down jacket are great. I don't hike in this thing because my god it gets hot fast. So, not to totally freak you out :). I. have yet to wash one of these shirts. Wool never stinks. I have worn this shirt for days, slept in it, never bathed, etc. Never stinks and I never wash them. I have a LOT of wool shirts I wear all winter and summer. This particular shirt comes in this 400g monster, as well as a variety of lesser weights. I have a range of them and wear them year round. Just beware marino wool is addictive. These things are SO soft and warm. OK, so I am 5'10" and 185-190 lbs. I am kinda muscular and "big boned" I guess. Normally, I would wear a large or maybe a xl in shirts. I don't think these shirts claim to be fitter, but yeah, they are. I like a loose shirt, so XXL works best for me. So, I guess they run small unless you are a stick. If you like fitted shirts, maybe get your size. I don't know if they pill because I've never washed on. If you DO wash it pay particular attention to instructions or you will shrink it or any other wool garment into something your toddler can't wear. Sorry for the book. Just trying to provide useful information on sizing. It always helps me to read reviews where folks tell how big they are an how sizing goes for a garment.

esta si es de uso para frio extremo. un poco pesada pero no pasaras frio si la usas como segunda o primera capa.

I would definitely buy these again. Warm on cold mornings, but not too hot when it warms up in the afternoon.

I use this mostly for single-sculling and it keeps me comfortable when temperatures hit the 30s and low 40s around Lake Union. Based on my experience, this is a high-quality thermal shirt.
