Great water flask. They fit
Great water flask. They fit in all my trail running packs and I will fill one half way and put it in my pocket for longer road runs or pack less trail runs.

Breaks Easily
On the beginning of a trail run, I tried to get a drink from the soft flask but when I when I started to, a plastic piece shot into the back of my throat and I swallowed it. Not only is 1. the product broken 2. a customer swallowed plastic (gross and can't be healthy) 3. this certainly poses a choking hazard to young children.

Slimmer Profile Helps
- Familiarity:
- I've used it several times
I've had a variety of soft flasks and trail running vests. The slimmer profile on these bottles makes it much easier to slide them in and out of the bottle pockets when full. They work great with the Black Diamond Distance packs. Nozzles are easy to take apart and clean.

Super great water bottle
This is meant to go with the running vest BD makes. I didn’t realize the vest comes with 2 of these bottles. I accidentally ordered this bottle. I love the bottle otherwise.

Not as big in real life
This flask empties quickly, yet is well constructed and suits my needs. I stuff it in my ski jacket for resort laps.

Fit perfectly in the distance
Fit perfectly in the distance 8. Should be included for the price. Strong plastic taste & smell. Still waiting for it to go away, but functionally the bottles are gray and serve their purpose well.
