Review on 🧴 Outgeek Neoprene Bottle Sleeve 2-Pack - Optimal Water Bottle Holder & Carrier by Wayne Girard

Just what I needed to keep my fluids hydrated during winter Alaskan fat bike tours. I went over an insulated water bottle filled with almost boiling water Accelerade with this sleeve. After 90 minutes of driving at -18 F it was still drinkable! Very impressive. It fits perfectly on bottles, down to the bottle cap but without, and makes it easy to remove from the feed bags on the handlebars. I suspect this case will add an additional 20 minutes to an hour of unfrozen life for your drinks in the bitter cold. I would also assume it would keep cold liquids cold in hot weather, but I'm unlikely to run into such conditions here.
