The Nathan HPL #020 Hydration Vest is one of the lightest hydration vests on the market today. When taking on long distance trail runs the HPL #020 has been shown to cut down on the nausea sometimes caused by waist packs.
Featuring a 3-way Propulsion Harness, 2 liter hydration bladder with filter-compatible screw-top closure and bite valve. The twin front holsters holds gels and treats. Additionally, there are two zippered rear compartments and a zippered front pocket.
