10oz Flask

Just stick one in your pocket, go outside and have fun. This bulk-free bottle shape is absolutely the best.

Have had several nalgene bottles over many years, and have enjoyed and had no issues with any, also happy with speedy service when ordering direct from nalgene. Needed a smaller footprint bottle for a certain bag I carry sometimes so I ordered the flask for that purpose (size was perfect). I noted 1 complaint from customer Shari B about outer case and figured that must be a 1 off instance. Not the case! Ordered Blue Flask and outer case will not come close to staying on bottle.
Thought nalgene would have a Quality Control dept. that would follow up/thru on issues but guess not. I hope to continue to use nalgene products and this sort of issue is not indicative of products to come.

Worked extremely well for years, but now it’s extremely difficult to pull-up/open the out-flow “valve”

I love this flask. It’s a great size and the cap works really well.

I don’t understand the purpose of the outer case. The flask itself is well made. It seems to be an extra thing to deal with , extra weight, and extra plastic

Love this flask. Keep it in my golf bag with my favorite “birdie juice.” This is the only flask I’ve ever used that didn’t leak all over the place.

Work fantastic for all your flask needs

I bought a blue flask at REI several years ago because it was the perfect size for my travel needs. I got it home and enthusiastically slid the blue outer protective casing down to remove the cardboard product info card and wash the item before use. After washing, I learned to my dismay, the outer blue casing would no longer stayed on the inner flask without that piece of cardboard! That left me with three choices:
1. use the flask without the outer protective case. (Didn’t want it all scratched up)
2. keep a piece of cardboard between the inner
and outer layers (tacky)
or
3. Put the flask aside and just accept it was defective.
So I hid it in a drawer and forgot about it until it was recently re-discovered. Still being upset about my bad purchase I decided to reveal the flaw in an online product review.
There you have it.
I would NOT recommend this flask.
