Onsie new and old

I am a male 5'7" 160LBS, and bought a S black onsie a couple of months ago, also still have and wear a S onsie purchased about 8 years ago. Material has held up very well. Material does not pill on the outside and the fleece inside will keep you warm. My basement in about 12C during the winter and 19C upstairs. No problem in staying warm. Advantage of a onsie over pants and shirt, no cold air comes in the back which really helps. Delivery was quick, and will consider buying further products and recommending Polar Piece to my friends.
