are Compatible with Camelbak Hydration Pack Reservoirs

Fits perfectly, it’s like a neoprene wetsuit for the Camelback bladder! Bladder is sewn well with cuts in the correct locations. I’m sure it will keep ice & water in the bladder cool! Looking forward to using it soon!

Haven’t actually seen how it performs yet but initial impression is good. Feels like good quality, the fit is perfect. I have the 3L Crux Camelbak bladder.

If you want to extend the life of the ice in your pack, this is a great option. It's simple, yes, neoprene and and Velcro, but simple is the best when you're interested in filling up and getting on with your day. No, it's not a an insulated cooler. But you can purchase a cooler if you want a cooler. This, however, is a simple, elegant and effective way to keep your ice around for longer. Additionally, this insulates your back against an ice-cold badder, which is uncomfortable and further melts the ice. The openings are true. The holes are where they should be. It fits well, the Velcro is good and it is well-constructed. Now, you might think the fit "seems" slightly off when inserting a dry bladder. But this is designed to hold a full bladder, and a full bladder expands when full. And when it's full it fit perfectly. Well engineered. Thank you to whoever thought of this. Great product. Camelbak should make this standard issue with the mill spec models. Recommend.

This is a great addition to anyone's Camelbak or any hydration bladder system one has. While my Hawg has good insulation it won't keep my water as cold as I want for as long as I need it to be. I sometimes leave my Camelbak in a vehicle all day because of work and I'm in So Cal, so it can get hot all day. After getting this insulator I used it not too long ago. I filled up my Hawg bladder with 2 trays of ice and water, put it in the insulator and then put that into my Camelbak, had it with me all day and the water stayed COLD. The only things I would change are the velcro on the back which I wish was on the top. And I wish the top corners were a little rounded instead of straight so it would be easier to zip up the Camelbak. But neither of these issues make it a bad product and I would definitely recommend this . It adds an extra layer of insulation that you need in hot weather.

If you like to drink cold water, it is a game changer! I fill the bladder with ice and cold water, then slide it into the bladder. I add a slim ice pack inside it to keep it all cold!

This is a meaningful enhancement to any Camelbak hydration pack—as useful on the ski slopes as it is on the hottest summer days. However, a simple U-shaped pouch for Camelbak bladders without cut outs for the water port and hose port would have been simpler, provide greater insulation and overall would be more effective. In our experience bladders don’t stay fitted in the insulator and the cut outs are sort of fussy as a result. Also, the neoprene that the vendor uses has a really overwhelming chemical odor that doesn’t easily dissipate.

Perfect fit, helps keep my drink cooler for a longer period of time..

Had to replace my bladder so I got the insulation with it. Works great in the Florida sun while walking the parks. Easily fit and put together.
