New to the forum at TB (in fact, it's been several years since I posted on any forum . . . yikes). Just received a new Brain Bag. Having owned Osprey, Sierra Design, Lowe, Mountain Smith, and Patagonia bags, I am impressed. Nice product. I noticed, however, on the right shoulder strap a hydration hose clip/hook. The Brain Bag does not have a dedicated hydration bladder pouch, though I suppose one could throw a bladder into one of the compartments. Just curious if others have noticed this and what have you used the clip for? Thanks.
