If you’ve ever worn your daypack and thought to yourself, “man, I wish this thing could compress to fit on my keychain,” maybe you’d be interested in the new Sea to Summit Ultra-Sil Daypack.

Stephen Regenold of The Gear Junkie got his hands on one and gave it a review, and said while it might not be up to snuff as a technical summit pack, it could be useful on short trips or for packing up dirty clothes at the end of a backpacking trip. I mean, if the thing can fit on a keychain when it’s fully compressed, there’s got to be some use for it, right?

It runs $28, weighs just 2.4 ounces, and has 20 liters of space when fully unfolded. In comparison, the REI Flash 18 I use as a summit pack weighs 10 ounces and holds 18 liters while retailing for about the same price. Huh – maybe the Ultra-Sil is worth a shot!

Whenever I go into the wild, even for a day, the last thing I need is a key to open non-existent doors plus, the most important thing in a backpack, in my opinion is quality of manufacture. However, such a product could be useful for other occasions, such as when you go to the local market and don’t want to carry a bulky, empty bag. I wouldn’t use it for true outdoor adventures, but it could have some uses, nevertheless.

I got that thing for Christmas. Don't bother. It is just a gimmick. Low quality and impossible to pack back up once it is taken out.

Agreed. Honestly, I don't know if I would be able to tell the difference between 2.4 ounces and 10 ounces when they're rolled up in my backpack with 30 pounds of other stuff, and I like that the Flash 18 still has a dedicated hydration sleeve and options for attaching other pieces of gear if you needed them.

This is kind of like a daypack concept car, then - cool enough to make you check it out, but probably not practical to actually use on the trail.

I'm a big fan of going ultralight, but I don't really see the point with a daypack. Why worry about those last 8 oz when you're just going a handful of miles?

On the other hand, I like the idea of a daypack you can store in your pocket or glove compartment and take it out in case of emergency....
