I wear these everyday at work
I initially purchased these underwear bottoms for my daughters, and on a whim tried on a pair of XL and they fit perfect. I wear hospital scrubs at work and they're very thin. For warmth and comfort I wear these underwear under my scrub pants and they work great. My only suggestion would be to offer a low rise underwear bottom that would accomodate the current styles, as it is we just roll the top band down and it works (maybe this would be a better option for the womens long underwear).
Love these undies!
I purchased a set of these REI long underwear for our son for use mainly as an extra layer for scout campouts. However, they have come in very handy for other cold weather activities as well. And my son loves them so much that he opts to sleep in them whenever he can. Obviously, one pair is NOT enough and I'm now back to order more for him and pairs for our daughter as well.
Great base layer and very durable
My kids have worn REI base layer products for several years and the tops and bottoms are the perfect choice for cold days outdoors. The fabric has lasted well after many washings and much usage. We have handed them down to other families and they still look new.
Really Cozy!
I just purchased two pair of these, and I think I'll have to buy more just so I can get them off of my daughter to wash them! She loves them, and says they are very comfortable and warm.
Perfect underpants!
These are my three year olds favorites! He wears them under shorts, pants, for jammies and camping. They are awesome!
