NATHANIEL K.wrote a review of Black Diamond Speed 22L Backpack on January 2, 2016
Familiarity: I've used it several times
I had an old speed 30 and thought it was good,except for the goofy ice link attachment. When BD came out with the new speed packs I bought the new speed 30 which uses a more popular type of attachment for tools, and has improvements in other ways too. I was so happy with it, that I went for the Speed 22 also, since I needed a lighter alpine pack that would climb better as a leader or follower. I've used it a few times now and can say it performs as advertised.
The straps are well sized and placed, and I don't think having lower side compression straps is necessary...the pack is slim enough that if you pack it well the load won't shift or need to be compressed there anyway, and it's a pair less straps to be getting tangled in your gear, etc. All the other features are just what you need, and no more (removable crampon patch straps, hydration sleeve, removable lid and waist strap). The rope catch is a must on this also, since you won't fit a Rope in this pack. It secures tightly and cleanly over the top with the rope catch and side compression straps. My only complaint on all the speed packs is that the material is perhaps too lightweight to last a lifetime or be dragging around the crag (still feels more durable than 80% of light packs out there) - this pack is definitely not a crag pack, but for alpine days or ice climbing, it's so awesome.
