The ultimate in packable convenience! Half the weight and packed size of Sea to Summit apos;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 apos;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).FeaturesUltralight 15D high strength nylon fabric Exceptionally compact packable daypack designSiliconized nylon fabric for easy packing and water resistance Asymmetrical zipper design for tiny packed sizeBar-tacks at stress points for added strengthBest Use: Summit Pack, Groceries, TravelDimensions: 11 x 8 x 19 in / 28 x 20 x 48 cm Fabric: Ultralight 15D nylon fabric for strength and durabilityGear Capacity: 18LPacked Dimensions: 2.7 x 1.9 x 1.8 inWaterproof: Water-resistant MaterialWeight: 1 oz / 30g Zip Options: One-way zipper closure
