It’s fine. It’s a Nalgene in a small size. If you are shopping at REI you probably already own a regular Nalgene. You know what to expect. This a smaller one that fits better in cup holders. But it holds less. You know what else should be less? REI’s annoying marketing emails. You barely have time to open your package and there REI is, blowing up your inbox asking for a review. Calm the bleep down, REI, and let people use their stuff for awhile before you annoy them for reviews. Or you know what? Give us free stuff for giving you our data. Or don’t, it’s a co-op, go back to your co-op roots and stop acting like every other obnoxious spamming company.
Perfect size for day hikes or the gym. Holds up well, doesn’t leak, and the wide mouth makes it easy to fill and clean. Love the design
I bought this because I needed a smaller sized bottle for a day at Disneyland. Perfect size to fit in my day bag that didn't weigh me down. The bigger insulated bottles can add too much weight, but this is perfect. Just enough to carry around and fill up at the water stations while walking around.
These are just the right size for a neighborhood walk. The top is wide enough to add ice, and the loop is sturdy enough to carry the bottle by even when full.
Great little bottle for storing olive oil for car camping.
The Perfect Plane & Trail Companion – Fits Anywhere, No Leaks! This bottle is incredibly practical. Its compact size meant it tucked easily into airplane seat pockets and backpack side pockets. From cross-country flights to the Camino de Santiago, it performed flawlessly and never leaked.
Great water bottle, I’ve had it for a while and it’s held up really well. The graphics haven’t faded or peeled at all, which I love. The wide mouth makes it super easy to drink from and also makes cleaning quick and simple. Overall, a really solid, reliable product.
I have quite a few REI Nalgene water bottles from over the years. They've all held up nicely. This one, however, really makes me smile with the snail design. Definitely a new favorite that I'm looking forward to using for years to come.
Fits easily into my lunch bag. I prefer the clear bottles with just the simple REI logo for work (all in stock were the opt outside theme). otherwise water bottle works well and doesn’t leak in my lunch bag.
Water bottle is a great size. CRAZY phrase of “powder supply specialist” was going to give this to a 9 year old only to feel like this is referencing a drug…..
