This Hot Chillys MTF Original Ankle Girls Long Underwear Bottom is a base layer bottom for kids that is unique due to the MTF (Moisture Transfer Fibers). This fiber has been designed to move moisture away from the body to the outside layers to insure warmth and comfort. This fabric is exceptionally soft, and constructed of a micro polyester for a great body conforming fit, each and every time that it is worn. The Antimicrobial yarn has a permanent anti microbial property to reduce odors while the UPF 40 is a rating system that measures the ultra violet protection provided by the fabric. The flat seam construction on the MTF Original Ankle Girls Long Underwear Bottom will eliminate the bulk from the bottom, while adding to the seam strength. Staying warm, and dry will be extremely easy with this ultimate plus in base layering clothing. Chillys knows exactly what is wanted and needed for the outdoor enthusiast, and has perfected this base layer so you can enjoy the outdoors in comfort, while you tackle the mountain and take on what ever comes your way. .
