## Description

Since its first release in 2008 the Ultra-Sill Daypack has impressed users with its incredible strength to weight performance. The use of siliconized CORDURA nylon and reinforcing bar tacks at stress points enables the Daypack to carry loads 250x its own weight. In 2017 the Ultra-Sill Daypack won the prestigious Backpacker Editors' Choice Gold Award for outstanding innovation in design, materials, and performance. To celebrate we have upgraded the Daypack and brought a new look to the entire Ultra-Sill bag range.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Best small light rucksack for daily use.
*by D***R on 30 April 2019*

Sea to Summit have the most durable,lightest little rucksacks for travel.I travel constantly ultralight and my last one is still going strong after 2 years of daily use and I carry alot of heavy stuff in it.

### ⭐⭐⭐⭐⭐ slightly bigger that the original version
*by W***G on 17 April 2019*

bought this as a replacement after my original one died after 5 years heavy use. it's a bit bigger and bulkier than my previous one (but not by much) but still really like it. Bear in mind this is meant to be a small secondary backpack that packs small. it isn't the most comfortable backpack for long use with heavy items, but that isn't what it is designed for. I use it as a secondary back when doing long distance backpacking to hold shopping/ dirty laudry/ valuables when at camp and love it.

### ⭐⭐⭐⭐⭐ Great
*by V***T on 20 May 2021*

Amazing bit of kit! Packs down to nothing and is perfect as a day-pack.
