The UltrAspire UltrAspire Zygos V5 Unisex Vest updated 14-litre capacity Zygos 5.0 with lighter and stronger fabrics is a versatile, high-capacity hydration pack. This durable, lightweight and comfortable wrap-around vest-style pack with full front and rear string compression allows for a stable low profile when either empty or fully loaded. The Zygos 5.0 includes a standard 2L reservoir (Hydrapak) that fits into the removable insulated bladder compartment.

The pack’s MaxO2 Form adjustable closure system secures and adapts to the pack’s load. Using a single pull, this innovative system can conform the pack to the body. Like the MaxO2 Sternum, the shock chords allow the pack to remain secure without impeding natural breathing. Featuring 8 on-the-go pockets there are 2 zippered shoulder pockets, a dual 4-way stretch mesh pocket, a pair of stretch mesh pockets (one of which is zippered and suitable for carrying a large cell phone), a zippered side pocket, and a magnetically closed side pocket. The main back compartment has been reinforced at the stress points with XT fabric which contains stronger than steel ripstop fibers. Twin z-pole attachments.

Available in 3 sizes to ensure a perfect fit.The many pockets on the front and rear offer many secure and unsecured storage options for every ultra runner. Whether fastpacking, training over long distances or competing in mountain or ultra races, this hydration backpack is a versatile solution for athletes looking for one pack to do it all.
