Patagonia Nine Trails Pack 15L review. Mountain Getaway reviewed this pack as part of its 2016 2016 Backpack Buyers' Guide.

Fit: Light! 10.8 ounces light (size small tested)—which translated into a hardly noticeable pack and featherweight fit. An Air-Flow mesh vest and small front stash pocket kept things comfortable upfront while allowing quick access to small items like a smartphone and granola bar.

Storage: Patagonia nailed the design on the Nine Trails Pack, especially when it came to the folding top loader with zippered main compartment. Although this pack can be compressed into the size of a watermelon, the main zipper allowed the pack to double in size when needed. The Nine Trails is perfect for a day hike where you only need the essentials.

Performance: The DWR finish held up well in a light rain, and the foam back panel with mono mesh was highly breathable. The hydration sleeve means this pack could go the extra distance if you were planning on more than a morning hike, although we were happy to stow a small water bottle in the main compartment for our quick 2-mile jaunt.

Manufacturer Description: The difference between finishing a long run and bailing often rests in your ability to fall apart, then put yourself back together again. Built for the full spectrum of fast-moving pursuits, this lightweight pack holds all of your essentials close to your back without compromising easy access when you’re on the move. The top-loading main compartment carries a shell, insulation, food and your choice of hydration reservoir securely and with minimal bounce. A small, zippered stash pocket on the lid provides secure storage for small items, and stretch mesh pockets carry water flasks or a hat and gloves. This light and supple vest, made from soft Air Flow mesh, breathes to keep you cool and comfortable in the heat. It has a skin-friendly edge binding that feels smooth on bare skin and two stash pockets for storing gels, lip balm and your sound track for the day. A supple foam back panel, made from lightweight mono mesh, won’t absorb sweat and breathes so you stay comfortable and dry. Made from 3.7-oz 100-denier high-tenacity nylon ripstop with a 6.25-oz 210-denier nylon semi-dull double-ripstop base. Both fabrics have a polyurethane coating and a DWR (durable water repellent) finish.
