Since its first release in 2008 the Ultra-Sil® Daypack has impressed users with its incredible strength-to-weight performance. The use of siliconised CORDURA® Nylon and reinforcing bar-tacks at stress points enables the Daypack to carry loads 250x its own weight. In 2017 the Ultra-Sil® Daypack won the prestigious Backpacker Editors’ Choice Gold Award for outstanding innovation in design, materials, and performance. To celebrate we have upgraded the Daypack and brought a new look to the entire Ultra-Sil® bag range.

  • Made from siliconized Cordura® nylon to provide strength and long-lasting performance with minimal weight
  • Simple, streamlined design features a half-moon, 2-way zipper across the top for easy access to the pack's main compartment; has no pockets or hydration sleeve
  • Adjustable thin nylon straps; stress points are reinforced with bartacking for increased longevity
  • The Ultra-Sil Daypack stuffs into its own tiny built-in pouch that has a drawstring closure and snap tab for attaching to a key ring
