The opinion of Aventure Nordique

Sea to Summit's Ultra-Sil Nano DayPack is a lightweight, rugged backpack made of siliconized Cordura nylon, with strategically placed reinforced seams for maximum strength.

Its zipper and nylon fabric make for a very compact package when folded. It can easily be stowed away in a pocket or hung on various supports (key rings, hooks...) thanks to the carabiner on its integrated carrying pouch.

With a capacity of 20 liters, it's ideal as a day bag, or as a back-up bag for travel or trekking.


  • Large capacity and super strong.

  • Reinforced shoulder straps

  • Webbing loops for a bike light.

Points to remember

Ultra-light, compressible backpack. Multi-purpose and sturdy. The back is made of solid, non-ventilated fabric. Includes main compartment and carabiner for hanging.
