Bladder Insulators are Compatible with Camelbak Reservoir Water Bladder. Will fit MIL Spec Antidote and Crux

5 Stars So Far...I am giving this five stars so far. Good quality thick neoprene. What looks to be solid construction. The stitching on the tops and bottoms look solid, and there is a nice long strip of Velcro on the back. The holes that are cut on the front may appear to be small, but once you get the neoprene seated around the opening of your reservoir, it fits very nice and snugly. I am using a Camelbak Crux 2 liter reservoir. The fit inside is not 100% spot on but it’s darn close. Unless this sleeve is made for a specific reservoir, I would question if anything would fit 100% perfect, so I am not taking anything off of my score for this.I also have the insulated sleeve for the tube, and it fits perfectly. So this runs five stars as well. It does add with to the diameter of your tube, but that’s just part of the deal having it. If you have attachable anchor points on your backpack, they may be too small for the tube and insulator sleeve.I will be inserting my reservoir with insulator into a 5.11 Rush 12 backpack. I know it will fit fine. The real test will be how well it insulates the water inside the reservoir. I will be going to the Indy 500 next weekend, and I plan to use this on race day. That will be the true test of how well it keeps ice water cold.Overall, I am very pleased so far.

I ordered this insulator after I went on my first hike with my 100 oz. Camelbak Omega bladder. It turns out that when you fill your Camelbak with ice water, it will sweat like crazy! So I decided to try this insulator out. It works great! My water stays cold about three to four times as long as before, and it keeps my Camelbak from sweating through my backpack. The quality of the insulator is really good too. It feels well-made and like it's going to hold up for a long time. Just make sure you order the right size for your bladder. I've been using this insulator for about 6 years and it still works great!

Well sewn with quality materials. Would be 5 stars but opening doesn't align with my 3L opening. Tube hole does fit. I would recommend.

Really improves water temperature. I work in construction, outside in 90+ desert heat so cold water is a priority. Adding 28 ice cubes, water stays ice cold for about 3 hours, cold 4-6 hours and remains cool for up to 8 hours. This tube cover is an effective upgrade to my hydration pack and highly recommended it.

Very well-designed and great quality and fit.

This is a simple product, but that's a good thing. The product fits perfectly my Camelbak; not too snug, not too loose; just right. The tube cover also went on without a hitch. Now in terms of the pragmatics, I really didn't find that the tube cover really does anything in regards to keeping the liquid cool and if you really think about it, some neoprene isn't going to keep cool a little bit of liquid within that tube. I'm not even sure what benefit there is in re: insulation value there is for the main bladder (in terms of having that piece of neoprene), but the main benefit for me is that the neoprene protects and really effectively deals with the condensation that results when the camel bak is filled with ice etc... This is a really huge deal for me in that I have a lot of photographic equipment close by in the bag. Anyway, depending on your goals / uses, this might be a great product. By the way, well built.

Thanks so much.
