Alpine Chalk Bag

4 out of 5 stars

Why We Like The Mammut Alpine Chalk Bag

From multi-pitch snacking to snapping pics at the chains, the Mammut Alpine Chalk Bag carries the necessities. The shape-retaining opening makes it easy for our fingers to take a dip, while the 3 secure pockets stow our phone and fuel. In case the wind picks up, the bottom bungee has an extra layer stashed for us.

Great Design, But Strap Loosens

I've put it through the wringer

I love this chalkbag - so many pockets and features! It's amazing how many snacks I can pack into the outside pocket, and the inside pocket always holds a little knife and lighter. Sunglasses in the stretchy side pocket, and a layer and/or hat secured to the bottom. Just remember, the more you pack in, the smaller the chalkbag opening becomes, but it's not too bad. I've been glad to have the double-closure buckle a few times, usually when I go to unclip the hip strap on my backpack on a climb... oops wrong buckle, whew. The one downside is the fact that the webbing strap is slippery enough to loosen while climbing. I will be replacing it with an adjustable loop of 6mm cord (probably a good idea anyway, for security and emergency purposes), which renders the safety buckle useless. If this strap material was changed to fix this issue, it would get 5 stars from me.
