This Sea To Summit Ultra-Sil packable daypack compacts down to an ultra-convenient size for everyday carrying, unpacking to offer enough space for bagging a peak or just getting the groceries home.

  • Constructed from siliconized Cordura® nylon to provide strength and long-lasting performance with minimal weight
  • Siliconized nylon is highly rip and tear resistant; the fibers stretch under pressure instead of locking together and tearing
  • Simple, streamlined design features a half-moon, YKK 2-way zipper across the top to gain easy access to the pack's main compartment
  • Stress points are reinforced with bartacking for increased longevity
  • The Ultra-Sil packable daypack packs down small to fit in pockets, purses or even on a key ring
