Review on 🧊 Nalgene Bottle Sleeve: Ultimate Protection and Insulation for Your Hydration Companion by Frank Harwood

I ended up returning it and got it fully insulated with a zipped cover around the lid. The fit was just super comfortable and difficult to achieve with warm bare hands in my apartment, and I knew it was going to be even more difficult with cold gloves/mittens on a backcountry winter hike. It also didn't feel like something that could adequately protect my water from freezing, especially with the lid open.
