The WR1 is a light yet large sports training water waist belt. It comes standard with a 1.2L bladder and tube system, which is insulated for use in winter sports. The WR1 is large enough to carry all the essentials along with the water while still being extremely light and ergonomic for unrestricted movement. An LED light on the back with two modes keeps you visible for safe, night-time training. It is fitted with an adjustable, velcro-strapping waistband for quick adjustment and removal.
