A: Yes it does shrink. The shirts on the pants are both long I was surprised at the length. The pants regardless of size has a 33 1/2 inch inseam. Most thermal bottoms are a 31” inseam on the larger sizes and a 29” for small and medium sizes. Plenty of room for shrinkage. Do not order a larger than normal size. For layering and warmth you want your thermal to be snug to your body. If it is loose, cold air will fill the space between the garment and your body. It has a light-med thickness. That is what you want for layering. Hope this helps others when deciding on whether to purchase. The price for these thermals is excellent.
A: It has some Cotton in it so I am going to assume it can.
A: No it does not.. It is 60% cotton
