Some more info on the alpha SL 30 beyond what was in the review from earlier this year. Time will tell if they took it too close to the stupid light line, looks very minimal. The new fabric is most interesting to me - some seriously cool tech behind it.
Compared to the tufa mochilla alpine 33 (https://tufaclimbing.com/) which comes in lighter and with more features, I'm not entirely sold on the alpha. I'm sure it'll be a very capable pack, but the lack of some features (proper ice tool attachments, daisy chains, compression straps, etc.) limit its applicability in my opinion. Would have also liked to have seen nicer hardware, similar to the tufa or the blue ice alpine hauler (https://us.blueice.com/products/alpine-hauler).
Interested to see how it performs.
EDIT: They updated the product page with the final images - looks much more fully featured, with proper ice tool attachments, compression straps, and a smaller logo. Looks great and aligns with what was reviewed earlier this year.
