Backcountry Research Tülbag was comparable to a generic phone case, so I figured why not?
I must say I'm quite pleased with it. It's shape is more conducive to fitting my tüls in and as a super bonus it has a non-slip backing that helps prevent other items, like your mini-pump from jettisoning from your pockets. The zipper has a big loop making it easy to access with gloves on. I chose red so I would be less likely to forget it trail-side and they didn't have pink (Mrs. CB2 is starting to wonder about me and all the pink).
Backcountry Research has you cover (or at least your tül covered).
