Not content with their award-winning Ultra-Sil Daypack, Sea to Summit has gone one step further to create the Ultra-Sil Nano Daypack. At just half the weight of its predecessor, the Ultra-Sil Nano is the perfect accessory to any outdoor trip; from backpacking and travel to on the spot shopping bag, or even an extra tote for day trips. Weighing a mere 30 grams and only the size of a chicken egg, this 18-litre bag packs down into an integrated stuff sack - small enough to pop in a pocket or even attach to a key ring. The minimalist design features a single zip closure with Siliconised nylon fabric to protect from rain while bar tack stitching delivers a tough design for outdoor use. Strong, yet compact and light, the Ultra-Sil Nano Day Pack makes the perfect gift for everyone from backpa.
