Exact same as the Outdoor Vitals Skyline 30 ones
It’s solid and the best ones on the market. I have zero idea how I can even complain about it but it does exactly as advertised and don’t notice anything wrong with them. Bought them for my outdoor vitals skyline 30 since I lost one due to tsa. But for what it is I love them. I don’t have any leaks, stores flawless in several running vest I own and two different backpacks, it’s easy to carry and no funky taste and they are easy to clean so I don’t mind putting in some tablets in them even if trailrunning a two day trip. Plus I love the straws so it’s right by my face so I don’t even need to reach and drink instead I just turn my head and bite the valve and drink. It’s just all around a good design

Love these for a run vest!
Love the flip top!!! Makes it much easier to refill while running so you don’t have to remove the bottle from your vest! Lid can be a little tricky to close, but I think with some use it will get easier to snap! Love the semi structured bottom allowing it to dry better.

Good quality
Great addition to son's collection and they were used in the cocodona 250. Perfect size, sturdy product and worked well for the race.

Amazing for trail race
One race in, and I'm in love. I have that common salomon vest, and had to replace the hydrapaks. These are bigger than what I had but still fit. Running with the straws was a mixed bag - I'm still working on the best way to keep them from bouncing around while also not being pressured to my neck. The access for a quick drinky drink was amazing. These also feel thicker than the Salomon version that came with my vest. These are worth the upgrade - though, I haven't tried other brands for a true comparison.

Hydrate is the key !
These are a life saver while out hiking. The pack light when not in use and also do a good job of keeping your drinks a little cooler than some other products I've used in the past. Quality made and very durable, no leaks at all after months of use.

Do NOT choose a bottle with a flip cap closure!
The flip cap will NOT stay closed! The third time I used this bottle after filling it, the "snap" closure would not click shut. Not usable.
