Sea to Summit's Ultra-Sil Nano Daypack is an ultra light-weight and packable bag that you won't notice carrying until you need to use it. Perfect for last minute shopping or little days out from your base camp.

Sea to Summit says:

Half the weight and pack size of our 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 minimum weight.

The asymmetrical zipper and siliconised Nylon Nano fabric helps to reduce its pack size down to that of a chicken egg.

With strength well beyond its 30g weight, our 18L Ultra-Sil™ Nano™ Daypack can carry heavy loads up to 20kg.

Sea to Summit's Ultra-Sil Nano Daypack is incredibly light-weight. At a mere 28 grams and packs to the size of an egg there is no excuse not to have a bag on you for last minute shopping or for little days out from your base camp.

For such a light bag the features are minimal. The shoulder straps have no adjustment or padding. The opening is sufficiently large to easily get items in and out. There is small loop on the top so the bag can be hung up. The 15 denier high strength Nylon means the bag can carry loads up to 20kg! Though that wouldn't be comfortable.

Really tiny backpack when closed in the pocket but looks tough enough when pulled out. I had the previous model and the only thing missing are the adjustments of the shoulder straps...
Original review:
Zainetto veramente minuscolo da chiuso nella sua taschina ma sembra abbastanza resistente una volta tirato fuori. Avevo il modello precedente e l'unica cosa che manca un po' sono le regolazioni dei spallacci...

Easily tears

I loved this bag when it first arrived. It is indeed super small and light which means you can easily bring it along with any kind of trekking gear. I decided to use it as a way of keeping valuables together during a bikepacking trip. I was wearing it as a backpack whilst traveling on the train to get to the start of our route, and had it stored in my panniers the rest of the time. It only ever contained things like my wallet, phone and my face mask (no keys or anything else sharp). On the very first day, it started developing tears along the bottom and by the time we had to take a train back four days later, I couldn't use it anymore because I was worried about it my valuables falling out if the tears got any bigger. Honestly, I could have just used a plastic bag instead...
