Durable insulation for variable temps

Constructed from neoprene wetsuit material, the sleeve delivers durable protection and triple-layer insulation. The result is a reliable buffer against heat and cold, helping maintain a stable environment for the liquid inside as you switch from hot sun to chilly shade. This isn’t a claim about outcomes, just a protective context for your hydration gear during a wide range of conditions.

Flexible mounting and quick access

Numerous attachment loops on both sides give you multiple ways to secure the sleeve to the outside of your backpack using rope or carabiners. A hang hole on the backside enables secure hanging inside a pack, while dual drink tube ports on either side offer left- or right-hand access. Flaps cover the fill cap and base connector for added protection and reduced snagging.

Compact and lightweight

Measuring 17" x 8" x 1" and weighing about 7 ounces, the sleeve stays unobtrusive while providing insulation and structure to the bladder as liquid is consumed. The design aims to maintain a balanced feel in backpacks without adding unnecessary bulk.

Real-world use

Ideal for running, hiking, cycling, snow sports, camping, and other outdoor activities. The sleeve’s versatility also suits tactical or field-use situations where dependable insulation and organized hydration matter. While a single sleeve can’t replace a complete hydration strategy, it can simplify setup and protect your liquid inside during complex trips.
