Ultra-Sil Nano Day Pack

Sea to Summit

The ultimate in packable convenience! Half the weight and packed size of Sea to Summit's 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, Sea to Summit's 18L Ultra-Sil Nano Daypack is strong enough to carry heavy loads up to 45 lbs / 20kg (although the non-padded straps are far more suitable for those unplanned smaller transport needs you will face on your travels).
