i have this one and love it. it's by far the most used ultralight soft good i own, though my tufa rock climbing chalk bag and my ultralitesacks trail wallet are strong contenders for #2 and #3. i think it's a good idea to have a small collection of really high quality bags; i just repurposed a large ditty bag out from storing spare things, to being a dedicated container for climbing shoes
