Warm, Comfortable, and Perfect for Cold Weather!
I purchased the PISIQI Thermal Underwear Set for a recent ski trip, and I’m extremely impressed with the quality and comfort. The material is ultra-soft and stretchy, making it feel more like athletic wear than traditional thermal underwear. The fleece lining is incredibly warm without being bulky, and it kept me cozy even in freezing temperatures. The fit is true to size and offers just the right amount of snugness without feeling restrictive. I wore the set under my ski gear and also used it for layering during outdoor hikes — it worked great in both situations. It also washes well without losing shape or softness. If you’re looking for a warm, lightweight base layer that feels good on your skin and performs well in winter conditions, I highly recommend this set. Great value for the price!

They are of very good material. It is soft and comfortable and it is the best thing for winters. I live in a cold climate and go around by bike, and these were definitely helpful with that. They are thin, so you can use them under your actual clothes without problem.

Great buy
Warm and great for daily use under jeans due to its perfect slim fit. Not sure how warm it would be for outdoor work that requires standing outside for many hours in cold weather (you may want to look for warmer options). Buying tip: If you normally buy an XL sweatpants, you should buy size L underwear, as it will only keep you warm if it fits tightly against the body.

Runs Small – Size Up
As others have mentioned, these thermal long johns run small. The fabric is not as soft as some others I’ve tried, but the neckline is generously sized and comfortable. I recommend ordering one size up for a better fit.
