The Trail Jam Waist Pack is the Goldilocks in our line of waist packs: it's that "just right" size for short to medium adventures, and is equally at home on the trails or around town. (Pro tip: this pack looks great when worn as a cross-body bag.) It's slim enough to fit comfortably under a jacket, yet has enough storage to easily hold your phone, keys, wallet, snacks, sunscreen, or whatever else you might need for the day's journey. An internal key clip and card slots keep things tidy, while the padded mesh back panel keeps things comfy.
