UltrAspire Speedgoat 3.0 Belt

Type: Accessories
Inspired and developed for ultramarathoner, Karl Meltzer, the UltrAspire Speedgoat 3.0 Belt was designed for the runner looking for a stable waistbelt that allows you to carry hydration and other essentials for hours on the trail. This belt includes two UltraFlask 550 ml Hybrid Bottles which supply enough fluid for hours, while 4 varying-sized pockets between the front and back offer storage for your phone, gels, keys, and other small essentials. Its Ergofit shape and conical design sit close around your waist for added comfort, and an adjustable strap further secures the belt to prevent unwanted bouncing. Elastic straps on either side can lock down a light jacket or trekking poles when you're adventuring out on the trails.
