Used these to keep water from freezing while winter climbing Mt Washington (wind chill -30 F). At 5 AM I filled two nalgene bottles with boiling water and then put them in these insulators. By 11 AM I had been on the trail for 3 hours and the water was still hot. By 3 PM when I got back to my car the water was cold but not freezing. Standard 1L nalgene bottles fit fine. Very easy to attach to outside of pack. Only con is the tough zipper.

It's very efficient to keep water liquid during cold weather. The only critic is that it's hard to get a regular Nalgene out of it but I guess it gets easier after many uses.

I bought two of these for winter hiking and backpacking. Used them for the first time out on a frozen lake near the White Mountains in New Hampshire filming and photographing dog sled races. Used one to hold a one-liter bottle of water and one to hold a one-liter bottle of hot coffee. The coffee stay warm for hours and the water never froze, despite 15° temps.

Must-have in my winter equipment. With a standard Nalgene, hot water will still be warm at the end of the day even in -20C (or lower) weather. I've never used it in warm weather, but I'm sure it would be equally suitable to keep drinks cool. I like to use it winter camping where during the night I'll put my Nalgene filled with near-boiling water in this, close to my feet, and open the Water Bottle Parka's top zipper more or less to manage how much warmth I want to let out to keep my feet warm.

Chilled my bottle the night before, got up dropped the cold bottle into Parka and went out to the lower elevations and heat of the SL Valley. Drank out of it around noon and then the rest of the day, cool beverage.... Only concern was the condensation I had to drain out at the end of the day, I feel that is a small price to pay for a cool beverage. When the snow falls I'll see how it holds up for a hot/warm drink.

Using this to carry water on my backpack and my ATV. It keeps my water cold despite the brutal summer heat of the deep South.

Perfect to attach water anywhere. Keeps water from freezing. Easy access zipper. Durable.

It is a little shorter than I was thinking it would be. I bought this to store my Britta filtered water bottle and it is wide enough tall enough. It fits my smaller water bottle but not the larger one which is unfortunate. It does keep it nice and cold though which is very helpful since the filtered water bottle is not insulated and most filtered water bottles aren't and since I prefer filtered water, I always have trouble keeping my water cold. This product definitely helps solve that problem.
