Hardside Hydration Reversible Bottle Sleeve for Nalgene Bottles

Works well. I live in the tropics and hate warm or room temperature water. It wont keep it cold like an insulated bottle does but it keeps it cool for longer that it would without the sleeve. Very happy.

Insulated bottle sleeve

Great idea and love the camo colours

Great fit on my Nalgene and helps keep my water cooler longer. Also the added thickness to the 15L Nalgene makes for a more secure fit in my hiking pack. Can’t speak for protecting my water freezing as I haven’t used it in that type of climate yet. Solid quality as usual from the crew at Hardside Hydration.
