Cirrus 9L Backpack

Black Diamond designed the lightest backpack on the market so you can take it anywhere. The Cirrus 9 only weighs an ounce and packs down to the size of an egg, so you can stow it in packs for backpacking, climbing, or even traveling internationally. It's a great summit pack whether you're hiking up there, or climbing a multi-pitch. The Splice Adjust shoulder straps offer an innovative, minimalist-minded way to provide an adjustable fit.

Decent pack.

It's incredibly small and lightweight. Great to bring on a multi-day trip if your day trips with it aren't too intense (otherwise it might be worth the extra weight to have a little more capacity, functionality, and comfort). My only complaint is that I wish the stuff sac for it was a little bigger. It's great that it is so small (size of an egg), but it's a bit of work to bet it back in - I'd rather a slightly large stuff sac that allows you to more quickly and easily get it back in.

Very light

Handy when you are going on a quick hike and need to carry waterbottel or light snacks. it's extremely light. It's not the most comfortable bag if you want to carry something heavy though, but I guess that's what it was made for, it's light and packs up very small again so it serves a great purpose for me to pack water for my dogs when hiking in the heat as I need my hands clear to handle them and don't want to carry a big bag just for water.

Extra light pack

Ideal as emergency pack or for carrying light items like a rain jacket and a headlamp. Just a few things could be improved, like the strings of the straps are too long and it is just too difficult to put is inside the stow pocket .

Great little pack with one flaw

I love this little summit pack. It’s great for a puffy, shell and bottle for a dash to the summit. There is one thing that is just a bit off that would make it perfect. The little pouch that you stuff the pack in is too small. It’s time consuming to use it and so I never do. Might as well not have it. Double the size of the pouch and this pack would be perfect

Perfect little pack

Not a bag for long hikes where you need to bring gear but a really nice thing to have if you know you'll be taking off layers and don't want to carry an empty bag just for that

Coolest Backpack Ever

I'm so impressed by this little bag. Lightest backpack I've ever used and it packs down ridiculously small so you can just keep it in another larger backpack or in your pocket just in case you need an extra bag for any reason. Great for fast and light climbing objectives!

Super compact off router

I bought this to help with backpacking trips - sometimes water sources are off trial so I’ll rest my primaire back and load this up with empty reservoirs. Saves lugging 30-40 lbs 3 miles round trip for the only water on the route - and it only weighs one ounce! Can also be used to venture to great vistas.

Super crazy light

Actually weighs one ounce?? This thing is perfect to take travelling with you and use for a day trip to the beach or even just to carry a couple extra layers of clothes on your back, then it slips in your pocket when you Decide to layer up! Love it

Tiny and light!

The included stuff-sack is the size of a golf ball. Incredibly convenient as a satellite bag, or for unexpected shopping.
