Extremely light and packable the UltraSil Nano Daypack is the perfect travel companion. This featherweight daypack can be easily stashed in your pocket or on your keyring, yet it offers 18L of carrying space. The asymmetrical zipper and siliconized Ultra-Sil Nano fabric makes for a compressible daypack that packs down to the size of an egg. Its construction gives it strength beyond its 1 oz / 30g weight, however, the non-padded shoulder straps keep our recommended maximum comfort load limit to 10 lbs / 4 Kg.FEATURESUltralight 15D high strength Ultra-Sil Nano nylon fabricExceptionally compact packable designSiliconized nylon fabric for easy packing and water resistanceAsymmetrical zipper design for tiny packed sizeBar-tacks at stress points for added strengthExceptionally compact
