Sea To Summit Ultra-Sil Nano Daypack yellow The ultimate in packable convenience! Half the weight and packed size of our award-winning Ultra-Sil™ Daypack, this foldable daypack can be easily stashed in your pocket or on your keyring as the perfect travel daypack. Ultralight 15D nylon fabric, strategically positioned bar-tacks, and streamlined paneling ensure maximum strength for minimal weight. The asymmetrical zipper and siliconized Ultra-Sil™ Nano™ fabric make for a compressible daypack that can pack down to the size of a chicken egg. With strength well beyond its 1 oz / 30g weight, our 18L Ultra-Sil™ Nano™ Daypack fabric and construction are strong enough to carry much heavier items than you might think. However, the non-padded shoulder straps keep our recommended maximum comfort load limit to 10 lbs / 4 Kg.
