If you’re looking for a water bottle hip belt that doesn’t bounce, you’re naive. The best you can do is tone things down a bit with padding and the Nathan Elite 1 is about the best you can do.
The Elite 1 is at the top of Nathan’s single bottle product line, with comfortable velcro adjustable closures that replace the hard plastic buckles of its less expensive models. You pay a little more for a little less weight — the pocket of the Elite 1 is mesh fabric, lighter but not so durable as the Nathan Trek.
Less fancy, less pricey but still functional, the Nathan Triangle has a plastic snap buckle and adjustable belt. Seems backwards that this should be cheaper than velcro, but you pay more for comfort. The buckle could be a sore spot on your hip. The other side has plenty of padding and the same good features as the more expensive Elite 1. With some trial and error you can find a position that works.
Available in several colors, the Nathan Trek is a good compromise. Adjust the belt so the buckle doesn’t ride on any bony points. The pocket is big enough for keys and ID and small personal electronics, and the fabric is good enough to give those things a little bit of protection. The Trek should get you through a sudden rain without soaking your cell phone.
While it won’t replace a bouncing canteen with total comfort, the Trek makes things better. Better is nice.
