Bought a fully hooded Ninja suit and liked it so much I bought this for around the house/sledding/snowball fights/outside work during winter, was able to donate 5 mis-matched never fit right thermals after buying this! The wicking is awesome and keeps you warmer than other suits or combo's, we lost power for 5 days in 20º weather but I wasn't cold, inside or outside. There are no seams to rub you raw anywhere, it doesn't snag, pill or pick up other fabric fibers or cat hair but it does take getting used to the zipper for the bathroom (plan ahead). Its softer than other fabrics but not bulky so you can wear clothes over it or just the suit without everyone knowing what kind of undergarments you wear - or don't wear. My long, curly hair also does not tangle on the collar, that is one fight I've had too many times with a really bad outcome.
At 5'3" 105lbs the size chart is off, an XS fits perfectly so order a size down to get the best fit.
