Took this on a six-mile hike and barely noticed it bouncing around, which says a lot since I usually hate slings. The bottle pocket actually swallows my full 32 oz Nalgene without stretching out, and there's still room for my phone and keys up front.

The 32 oz bottle slot is the reason I bought this, and it holds my Hydro Flask snugly without wobbling when I'm hiking. The crossbody strap stays put on one shoulder, and I’ve got room for my phone, keys, and a snack all at once—so it’s become my everyday errand bag too.

Finally a crossbody that doesn’t bounce around all day—the water bottle pocket sits snug against my back, and the strap is wide enough that it never digs into my shoulder. I’ve carried a full 32 oz bottle plus my wallet and keys on a few long hikes, and it’s held up perfectly without feeling bulky.
