SIMIYAMen's Thermal Underwear Set Base Layer Long Sleeve Top Ultra Soft Long Johns Fleece Thermals Leggings for Winter Workout

I'm very impressed with these and plan to get another set. They really are super warm, very comfortable, and unlike much thermal underwear, not ugly at all! They wash well and dry very quickly.

I bought 2 pairs last winter and found them comfy and warm. I bought 4xl and I’m 5’8” and 17.5 stone. Sizing is good. Soft and warm to wear. I just ordered another 2 sets for this winter. I love them.

I’m 5’11/ 80kg and bought size L; I am probably average height but out of the bag the legs are a little short, they are OK but a couple of inches longer would have been perfect. Otherwise perfect happy with them so far, they seem well made and are certainly warm. Fit everywhere else is good, a larger size would have been too loose and baggy. Had the legs been a little longer then I would have rated 5 stars.

Very pleased, ordered 2 additional pairs after trying one pair to see if they met my requirements, they did.A little on the expensive sided but survived four washes so far and still retains softness. Would recommend.I'm 54 kg and the small size fitted perfectly but sleeves a little on the long side but I'm 5'3" so expected therefore not a problem.

I wear suits for my work in a cold environment so I always wear thermal underwear. This one is perfect for my need. Its very soft and keeps me warm without sweating.it feel like spongy which provides airflow. I have ordered Medium size and its not too tight and not too baggy.its really ultra soft . The stretchy fabric didn’t hinder my movements so i can move freely while at the gym, office, or home. I have tried this and its perfect for all activities and will kept me comfortable. This set is soft against my skin, yet its strong seams won’t rip or tear prematurely, material wicked away moisture and kept me dry with no sticky or clammy feeling .So i wore them all day. I am sure it will last longer. Will order Small size as well for cycling.

I found all the different makers' size charts rather confusing with some even transposing waist and chest sizes so I was pleased to find David W's Simiya review with his height, weight and even age similar to mine; 5'10", 11st. I ordered L.It is a close/loose fit and very comfortable. It was 4C and dark outside, so I wandered around the garden wearing only the base layer and watching Jupiter, Saturn and Venus, which were lined up that night.I was only out there 15 mins, but surprised by how warm and comfortable I was.When cycling I experienced the wicking effect after a long hill. It didn't take long before my back felt dry and comfortable again. My other layers were trousers, light fleece and a showerproof top. Outside temperature 6C. The pee hole is very useful on long cycle rides. The Large size works fine, but I might get the Medium for cycling and maybe try it SUPing in cool weather instead of a wetsuit.

Got theses as I fish all year round and feel the cold a bit. There are not bad on keeping you warm. I got them in black Friday sale so very good value for money. Fit very well. Nice and soft. Stretchy so freedom of movement. But I will be looking at another set for more warms

These are excellent for keeping warm in these freezing winter days. Worn under clothes to do dog walks and keep you toastie warm. They also wash lovely and keep their shape so I would highly recommend them.

Very warm, fit well, stretchy and comfortable!!

I bought 2 different thermal wears just in case I wouldn't like this one, but this one fits better for X-small for me. The sleeves are a great length to wear on it's own. The other one has shorter sleeves for layering. I would buy this one again.

Great quality- especially for the price. Kept my husband super comfortable in snow and very low temps. He doesn’t wear them often so not sure how durable they would be long term but they have lasted fine for at least 5 wash cycles.

These are light but super super warm and I mean like by thin I would definitely recommend them and I would buy them again

Ok these are my husband's favorite ! He works out in the cold and said these are better than the name brand expensive ones he owns. They are so soft and warm. We have now ordered more because he loves them so much .
