## Overview

The Sea to Summit Ultra-Sil Nano Day Pack is an ultralight, packable 18L backpack made from durable 15D siliconized nylon. Weighing only 30 grams, it compresses to the size of a chicken egg and supports loads up to 20kg, making it ideal for travel, hiking, and everyday carry. Its vibrant red color enhances visibility, while reinforced construction ensures strength without added weight.

## 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).

Review: Lightweight and durable - Super lightweight but durable. I like the orange because it’s easy to see against the green of the trail.
Review: Best gear ever - 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.
