Product 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.

    A lot smaller and thinner than I expected

    A lot smaller and thinner than I expected
    Not exactly what I expected and I don’t expect it to hold up. It’s very thin material. It’s also very small and light though. I’ll throw it in my pack for emergency use. Definitely a day pack and not an everyday use pack.

    5.0 out of 5 stars Fantastic Ultra Light Day Pack
    Reviewed in the United States on September 4, 2020
    This is a great addition for any backpacker who might be making a day excursion. It is big enough to hold a couple of liters of water, some snacks, first aid kit and a jacket. What I like most about it is that I was able to replace one of my stuff sacks in my pack with it. It is also water resistant which is great!

    1.0 out of 5 stars Good for one time use. Does not last ...Weak material but compact size and Lightweight.
    Reviewed in the United States on February 11, 2020
    Purchased few months ago and used this bag just one time on a short trek, had it packed with some light clothes...bag tears very easily and material is not strong at all. Had multiple small tears in bag after just one use. Bag was very compact & light. Wrote manufacturer because they claim to have "lifetime warranty" had me send pictures and receipts just to tell me they won't cover it and I should buy some tape and repair it myself. Plenty of better quality and lower priced bags in the market.
