ZYGOS 4.0

A running pack that also works very well for bikepacking ultras. Masses of small stash pockets that won't spill gear when the going gets ragged. The 14l capacity is about the same as an large-ish seat pack.

The pack is lightweight and high capacity, a comfortable wrap around style with full compression allow for the lowest profile empty or fully loaded. The Zygos 4.0 can be used with a 2L reservoir, 550UltraFlask, or softflaks (not included). Expandable mesh on the back panel gives 4 liters of extra capacity as well as storage in the front with extra pockets.

NOTE - the ZYGOS does not come with bladder, like in the photo.

Description

Race Line: Built for the competitive athlete. Race Line focuses on Ultra & Trail running but can be used in any running scenario. Race Line products are sized to fit the athletic body, feature UltrAcool technology for maxiumum breathability on all race vests, made with very lightweight material for comfort during long distances, and created for pure performance.

Details

  • Lightweight, soft, breathable, but strong, large-holed mesh pulls moisture away from the body to keep skin dry and cool.
  • Silicone and PU coated feather-weight nylon fabrics resist water, abrasion and tears.
  • Max O2 Sternum™ for unrestricted breathing while maintaining a stable pack. Uses shock cord with good stretch for unrestricted breathing but also good rebound on the stretch for a stable ride. Patent Pending.
  • Plush feeling micro-fiber polyester edges, soft and non-abrasive against skin and clothing.
  • Sweat proof webbing—won’t absorb water or get saturated and heavy.
  • Safety stitched bar tack on all stress points.
  • Quiet, bounce free, easy to see and use, zipper pulls.
  • Zig zagged stitching over elastic for ultra-durability, increased stretch and rebound.
  • Simple, fast, easy in and out bladder attachment.
  • Magnon pocket for sweat-free pills, with automatic magnetic closure for rapid access to pills and other essentials. Patent pending.
