Kailey Cwrote a review of Arc'teryx Aperture Chalk Bag - Small on June 12, 2018
Familiarity: I've used it several times
I wanted a lighter and smaller chalk bag for outdoor / longer climbs and this product does the trick. Perfect size for my hands, and I love how it can be twisted closed to compact even more. My only complaint is you have to twist it one direction for it to close properly (I think it was counterclockwise?) If you twist it the opposite direction, it leaves a tiny hole in the middle and leaks chalk.
