This is a new, unused Komperdell Cross Flex back protection vest in Men's size M (medium). It was purchased for my son for Xmas last year for a ski trip out West and he never wore it. It cost $109.99 + tax. It still has the user's manual but we do not have the original mfg box. It is made of 90% polyester and 10% Elastane. It appears to be model # EN 1621-2. This is a vest that is worn like a backpack under winter jackets/ski clothing, etc. It can be used for any high risk sport: Skiing, snowboard, skateboarding, horseback riding, BMX biking, etc. Note that it is comfortable to wear and compact but you can feel that it is on when wearing it. it is comfortable and flexible enough not to impede movement.
