Very pleased.
On short hikes with my dog I have been carrying a water bottle and collapsible bowl in a small "freebie" back pack. Bought this so that I can dispense with all that. Lightweight and fits in my back pocket and I clip the bowl to a belt loop. Worked so well that I am purchasing a second one so I can carry two. Lighter in weight and more capacity than other offerings made of stainless.
Perfect purse bottle!
I bought this to take with me on long urban walks and tuck into the small crossbody bag that I carry. It is working perfectly, so spills, fits well, so convenient!!
Pass the flask
It's a plastic flask not much more than that. Oh, the rubber trim was peeling the first day.
Specific purpose
There’s no shortage of water bottles for sale and you probably already have your fair share, so do I really need another? Possibly yes. This one is well made and should last for some time. What sets this one aside from others is its convenient shape. It fits in my front pocket, and for those times when you aren’t required to bring a a lot of water, this one fits the bill.
Perfect for bringing water in a sling or hip pack
This flask is compact, cleverly designed, and well made. Most importantly for me, it fits perfectly in the little Bellroy Venture Ready 2.5L sling while still leaving room for my other gear. The only downside is that some people will assume I'm drinking alcohol. I'm pretty sure water molecules don't mind being in a bottle that's rectangular rather than tubular, people.
Out of stock
I’ve been asked to review this flask which I never received. I ordered with an REI discount coupon, but later got a message that they weren’t shipping it because it was out of stock. I repeatedly signed up for email notifications when it was back in stock, but each time I reordered it, I got the message that it was out of stock. So I give up
Rugged flask
This is a nice flask. The top seals well, and it's nice to be able to see the contents.
