Merino.tech Merino Wool Base Layer Mens Set - Heavyweight, Midweight, Lite Merino Wool Thermal Underwear For Men Top, BottomOEKO-TEX STANDARD 100

I'm buying this in advance for a cruise to Antarctica in February. This fit is perfect. I'm 5'8" and 154 lbs. It feels very comfortable and this is exactly what is recommended.

We ended up with pairs from this brand for the whole family. We get itchy from other merino wool brands, but these are great and so warm! We have different thicknesses for different weather!

XLG 320 heavyweight blk. Set 6'1" 190 lbs. Winter in the Pacific Northwest has been bitter cold this year, and I wear an assortment of long johns made from various materials, but none made from 100% wool. The fit is loose (not a bunch up under your outer clothing), and the quality of the material and craftsmanship is better than most. The wool material is soft and not itchy; I have no complaints. The 320 heavyweights are thick and have noticeable weight; again, I have no complaints. The versatility of this set is unmatched, allowing me to adapt to any winter activity.I have worn the set for multiple days and nights with temps in the negative degrees, working on equipment, loading firewood, shoveling snow, and operating ATV for extended lengths of time, and have stayed warm through coffee breaks and meals. Typically, when wearing my other sets, I will have to change tops if I take an extended break outside in a nonheated building because I'm soaking wet, and the cold starts setting in. I didn't have a problem with this set.I recommend these over my silk sets since they are better at wicking away moisture and keeping me warm when damp. Hand washing is a pain, so I'll see how things work on the "hand wash" setting on the washing machine. By the way, black shows every dog's hair, lint fuzz, etc., that you can imagine. I give it a 4-star rating for now. I will update you on the durability and longer-term wear in a few months.

Warm and Fit perfectly size medium on a 5’9” 168lbs male, Michigan resident.This was a much needed replacement to my thinner box store set. I got the mid weight and have worn them in the single digits with jeans and a mid-weight coat, I stayed cozy. It is soft with just a slight bit of wool scratchiness (this will go away with wear and a couple washing).I got the gift set of 4 pieces: top, bottom, socks, and beanie. The socks that it came with are very comfortable and kept my feet warm, which, is saying something seeing as my toes stay cold most of the time. So cold my toes turn white circulation issue. They are not 100% wool they have spandex in them for the stretch.The beanie is very thin and light weight, but does the job nicely. I would highly recommend this set to anyone.I am in mid-Michigan we do get into the negatives in the winter (especially when there is a wind chill). If your coldest days don’t go below 30 I would say the light weight with good clothes are good for you. But anything colder I would recommend the mid. If you are always negative for sure the heavy weight. I am also basing this on moving/being active and then standing for short periods of time, not just standing in the cold windy open.I hope this was helpful.

Very good quality. I will say that ordering my normal size did lead to a little extra room in the shirt all around and extra length in the pants.A cursory search online assures me it will shrink somewhat in the wash. All in all very comfortable and insanely warm and insulating.

i wear a large and so do my sons - the large was too big for us and we chose a medium - it fits perfect although the site recommends a large which is a little too large to hold in the body heat
