My go to water bottle
[This review was collected as part of a promotion.] I’ve been using the Pinnacle Soft Flask for my mid-length runs and it’s been perfect, especially on hot summer days. It’s really comfortable to hold and feels natural in my hand while I’m running, so I don’t even think about it. I also love the little pocket — I usually throw my keys in there, which is super convenient. It’s lightweight, easy to use, and makes staying hydrated way easier without carrying anything bulky. Definitely my go-to for runs in the heat.
Good soft bottle with room for improvement.
Good large bottle and the water does not slosh around while you run. A couple small negatives are that the strap stretches a bit too much when the bottle is full meaning that it doesn't stay close to your hand as you run and my hand gets very sweaty on the outer covering. Also really expensive for what it is. Overall however, I'm glad that I bought it as I no longer need to run with my running belt and bottles.
Great upgrade
I’ve been eyeing this bottle for a while, but was hesitant to buy. Likes: great size, doesn’t leak, easy bite valve, has boning that keeps its shape while emptying Cons: tricky to fill up all the way, gets a little strange in hand after partially empty
Great product but need a replacement bite valve!
Just used this for the first time, love it! I needed something that didn’t slosh when I run - found it! How do I get a replacement bite valve? My four year old son got it off and it’s nowhere to be found.
Nathan sports is my go to for all things running!!
