## Description

The Sea to Summit Ultra-Sil Nano Day Pack is the ultimate in packable convenience! Half the weight and packed size of the award-winning Ultra-Sil Daypack, this packable daypack can be easily stashed in your pocket or on your keyring as the perfect travel daypack. Ultralight 15D nylon fabric, strategically positioned bar-tacks and streamlined paneling ensure maximum strength for minimal weight. The asymmetrical zipper and siliconized Ultra-Sil Nano fabric make for a compressible daypack that can pack down to the size of a chicken egg. With strength well beyond its 1 oz / 30g weight, our 18L Ultra-Sil Nano Daypack is strong enough to carry heavy loads up to 45 lbs. / 20kg (although the non-padded straps are far more suitable for those unplanned smaller transport needs you will face on your travels).

## Customer Reviews

### ⭐⭐⭐⭐⭐ Lightweight and durable
*by  on Reviewed in the United States March 16, 2026*

Super lightweight but durable. I like the orange because it’s easy to see against the green of the trail.

### ⭐⭐⭐⭐⭐ Best gear ever
*by  on Reviewed in the United States August 29, 2022*

Hands down this is the most versatile piece of gear ever, I love it. My dog and I go for skates in the city. I can bring flip flops, bike lock, bottle of water, and a ball on this bag. Also after you set up a base camp backpacking it’s great as a day pack. Lastly, traveling I would use this cause it’s cheap and light.

### ⭐⭐⭐⭐⭐ Great Pack
*by  on Reviewed in the United States July 10, 2022*

I have 3 of the Sea to Summit Ultralight Day packs:1. The16 liters that I have attached to the seat of my road bike2. The 18 liters which I have hooked to my jeans belt loop when I am walking around The NYC3. The 22 liters that I take in place 18 when I know I will be doing a lot of shopping
