500ml Locking-Cap Soft Flask

These bottles have been fantastic! Super durable, absolutely no leaks and the lock works great! Fit perfectly in the Terignota Valhalla vest.
The only issue I have had is that the bite valve can pop off if the bottle is bouncing around while you are biting it and the contents will squirt everywhere if the valve isn't closed (locked), but as long as the bottle is secure when biting it I have had no issues with these bottles at all. Caulk that up to user error, which took me one time to figure out and I have had no issues since then. These are the best bottles I have and I will be purchasing more.

Exactly what I was looking for!

I love these locking caps on the Hydrapaks and Terignota does them best!

I love this flask for the mouth mechanism. It’s easy to drink from, and as you drink it also keeps the air out so that it doesn’t slosh and is easier to store. The locking mechanism is nice, though it does well enough unlocked that I don’t use it much. Other flasks I’ve used I’ve found it’s either easy to spill, hard to open, or you can’t drink fast enough. No issues at all with this one.

The one piece of advice I’d give is that when it’s filled up it’s too big to fit in the Sendero shorts. I’d love to see a smaller version of this that fits in the shorts, or most other average belts for that matter. It’s not really a flaw, just something to know going into it. You can also just fill it up less and jam it in.

Super awesome quality for the price! Love the locking feature!
