Rated 5 out of 5 by from I love this sleeve Wasn't sure what to expect from this sleeve, but I use my Nalgene religiously to track water intake. Since I usually fill my Nalgene with ice, I get quite a bit of condensation on the outside of the bottle and a small puddle forms necessitating the need for a coaster or something. This sleeve keeps my water cold for hours and seems to absorb most of the condensation without making a mess. Also the loop and the small carabiner are very convenient for carrying or storing. Not sure it is a necessity, but if you have the means, I highly recommend it.

Rated 5 out of 5 by from Keeps it cold & prevents "sweating" I bought this cover/sleeve for the purpose of keeping my Nalgene ice cold for a few long (9+ hour days) of classes. It did a great job. I removed my Nalgene from the freezer & added water on top of the frozen block I had, I slipped it in this sleeve, and headed to class. It did not sweat on my desk, in my bag, or on any of my books or papers. The ice block remained for about 5-ish hours and my water continued to stay cool; It never hot warm or hot.

Rated 5 out of 5 by from Does the job I bought this sleeve for my nalgene bottle to keep water colder longer on summer day trips or whenever I want cold water. It does help insulate the bottle. The material is like a wetsuit; foamed neoprene rubber or something. It is about 2.5mm thick, so don't expect this to insulate like a vacuum bottle, but it does help significantly and is not too bulky. With ice water in the bottle with the sleeve on, the outside feels cool but not cold. The fit is nice; snug and will not fall off accidentally. Fit looks like the picture in the description.

Rated 1 out of 5 by from Skip it - Nalgene makes a better version The bottle tends to fall out, and the tiny carabiner is the only attachment point. Instead, get model 2355-0009 directly from Nalgene. It's more secure and offers better attachments.

Rated 5 out of 5 by from Kept the ice at bay Worked as promised in near zero temps. Great solution to icing up on a winter hike

Rated 4 out of 5 by from Helps insulate bottle and prevent sweating This sleeve helped keep my water bottle cooler longer this summer and I avoided a lot of the sweating from the outside of the bottle that I normally experienced. It was harder to fit in my day pack's water bottle side pockets. Also, the binder clips broke on both sleeves I bought within the first few days of very minor usage so be sure and get a decent clip before leaving the store.

Rated 5 out of 5 by from Wearable on your belt Insulates well Does what it is meant to do The main point is you can wear it on your belt Thread your belt thru loop where the carabiner is Make for a very practical carry if you like it on your belt

Rated 5 out of 5 by from Great insulater! This works perfect to keep my bottle from "sweating" when I have it filed with ice water.
