Sea to Summit Ultra-Sil Nano Daypack dark blue

Half the weight and pack size of the award-winning Ultra-Sil Daypack, it’s easily stashed in your pocket or on your keyring as the perfect travel companion. Ultralight 15D Nylon fabric, strategically positioned bar-tacks and streamlined panelling ensures maximum strength for minimal weight.

The asymmetrical zipper and siliconised Nylon Nano fabric helps to reduce its packed size down to that of a chicken egg. With strength well beyond it’s 30g weight, the 18L Ultra-Sil Nano Daypack can carry heavy loads up to 20 kg.

15D Ultra Sil
A very lightweight technical waterproof 15 denier nylon fabric. 15D Ultra-Sil has a siliconised outer surface for improved water repellency to prevent the fabric from absorbing water and a PU inner face to create a water resistance of 1,200 mm and allow seam sealing.
