SoftFlask™ 500ml

I did a multi-day hut-to-hut backpacking trip and these soft flasks were perfect for quick access water either in my pack side pocket, or my janji trail tight pockets.
I had 2 of these- one for just water and the other for my electrolyte mixes. And when they were empty, they collapsed well till I could fill them up again. I felt well hydrated for the entire trip!

I appreciate that the flask has a wide mouth so I can easily fill it with fuel. However, when the flask is near empty, the cap digs into my leg. I usually run with the flask in the side pocket of my pace shorts

Great!!

Not much to a soft flask. Works as it should. Kind of a pain putting a soft flask back in the pocket but with a few more runs I think it will get easier.

This flask is the perfect fit for the Janjii running shorts ! Very comfortable for long races
Love it

Bought it as a backup and quickly moved into the starting rotation.

Great!

everything the other positive reviews say is right. I like the shape at the top - easier to slip into my shorts pocket.

Love the on/off switch for the nozzle. Saves wet story if flask gets pinched by tying your shoes.

There are better fitting and locking style caps for the price on hydra flask.

Love this flask, especially the closure on the mouthpiece.

Great purchase. Bottle is light very durable and I can take it in any get or belt.

I love the size and ease of use while running, and I didn't know how much I would love that it locks so it won't leak. It fits in my trail tight pocket and makes it easy to bring water and snacks along when I don't need to bring my whole running vest. The flask itself has a good shape that dries out easily, but the valve is difficult to clean and I noticed mildew building up.

I love how you can close the mouthpiece, I can fill them up and toss them in my car without worrying about them leaking. They fit in my Salomon ADV 12 perfectly.

First time I ever used a soft flask. I liked it. This I e is easy to fill and doesn't leak

Ran Chicago Marathon couple of weeks ago and the soft flask came in handy…👍
Fit in pockets on running tights/shorts is perfect

Fits in my janji tights perfectly

Appreciate its design and utility

I prefer my Temu / Amazon water bottles honestly. Especially at this price

Ran my first ultra 40mi with these. Easy to take fluids, and stash in the half tights, especially when a surprise downhill rock garden greets you. When I ran a marathon, I had a lot trouble drinking on the run from a cup, but I was able to take in 4.5L over 9 hours.

Amazing. Shocking it took this long for these to be a thing. With a big bladder it’s hard to know how much you’re drinking/how much you have left and you have commit to all your liquid being the same (water, lytes, etc). It’s easy to throw a few extra of these in the back of a pack and not worry about leaking. Game changer.

My favorite thing about janji gear is all the pockets and this fits in them nicely! I fill this 500 ml and run with it in the side pocket of the trail short or tight and it’s been wonderful. Love the locking lid feature too, preventing spillage while being jostled around.

I prefer this bottle to the Salamon - much easier to make sure it is not leaking, with the on/off.

Perfect for longer runs

I love the size and shape. Also, the flow lock feature is great to have.

Perfect for my long run
