Ultralight Stuff 18L Backpack

Osprey's Ultralight Stuff Pack has the room you need for a day's worth of gear whether you're hiking, multipitch climbing, or traveling across foreign cities. Stow the Ultralight Stuff Pack inside itself and pack it up in bigger climbing packs, then take it out after the approach and when it's time to ascend the hundreds of feet above you. The air mesh back panel uses minimal padding and breathable fabrics to keep your back comfy throughout. There's a top zippered stash pocket for valuables, and a stretch side pocket for water bottles.

Great for bicycle commuting, nice design

I've used it several times

I got this pack for commuting by bike and it's almost perfect, especially for the price. Feather light, comfortable, and great zipper construction. It could use a chest strap. The 'almost' is because the "Air mesh back panel" got my hopes up for better ventilation, which was something I was looking for.

great light backpack!

I've used it several times

bough this for a 10 day hiking trip in Canada and it was perfect for carrying items for a several hour or half day hike. i put sunglasses case, water, hand wipes, gloves, tissues, camera, and layers. Filled to capacity it did start to give some mild neck discomfort from the straps, but this was only because I think it was overfilled. for a less-full pack, it is very comfortable.

Instant storage!

I've put it through the wringer

Super stoked on this pack! I use it for the light commute to work, and for the extra packable storage when bikepacking. My favorite use of it so far, is when I need to run errands after wanting to get a ride in...It packs up nicely into my jersey pocket for the ride, then poof!, instant grocery bag!!

Durable and Lightweight!

I've used it once or twice and have initial impressions

Packs down to about the size of your palm, super light, and comfortable to boot. The best summit bag I've used or seen. Just get one already.

Well said, Robin! Thanks for the great review! Leta Osprey Rep
