From 50k to 100k.

Built for fast-packing and ultra runs alike, the UltrAspire Zygos 2.0 Hydration Pack provides ample storage space for necessities and fuel as you tackle varied, fun-type-two terrain. The Zygos 2.0 is a unisex vest, complete with lightweight and breathable mesh material that's reinforced by a silicone or PU coating for added water-resistance and durability. Unique to UltrAspire is the Max O2 Sternum strap, which is designed to promote unencumbered breathing and stability—without sacrificing durability or comfort. 

Additionally, the Zygos easily accommodates a two liter reservoir (which is included) for on-the-go hydration, while the front pockets are compatible with UltrAspire's UltraFlask, Formula 250, Human 20, or the Collapsible Bottle (none of which are included) to meet your hydration needs. A bevy of pockets keep necessities, such as fuel tabs, keys, or a phone secure, and the adjustable rear straps offer safe respite for items such as a trekking pole, ice axe, or extra layers.
