Packs down to the size of a tennis ball
+ View tech specsOur award-winning Ultra-Sil Day Pack is a minimalist backpack that has incredible strength-to-weight performance and packs down to the size of a tennis ball. The 30D siliconised CORDURA® fabric and reinforcing bar-tacks at stress points enable it to withstand loads many times its own weight.
With a 20L capacity, it's perfect for a summit pack, carrying groceries when on foot or on a bike, or as an extra traveling tote. The tiny packed size also easily fits onto your key ring, in a jacket pocket or a purse.
With non-padded shoulder straps, our load limit recommendation for maximum comfort is 15 lbs / 7 Kg.
With correct care, this pack can last many seasons. Just limit contact with sharp objects or abrasive surfaces as much as possible, since these can damage the fabric.
No. It's only water-resistant. Even though the pack is made with waterproof material, water can enter through the seams (which are not sealed) and zipper. A few minutes of light rain is okay, but getting stuck in a downpour would likely result in the contents of the pack getting wet.
The Ultra-Sil Day Pack is made from 30D Ultra-Sil Cordura nylon and includes adjustable shoulder straps and a daisy-chain webbing loop. It has a two-way zipper closure with a generous opening and weighs 2.5oz/ 72g.
The Ultra-Sil Nano Day Pack is more compact (packing down to the size of an egg) and made from 15D. It weighs 1oz/ 30g. With an asymmetrical zipper, lightweight fabric, and slightly smaller capacity (18L vs 20L), the Nano is a great option for those that need to save on weight and space.
