Bottle Bottle Thermal Sleeve 354ml Milan - navy insulated cover for 354 ml bottle

The Milan Bottle Bottle Thermal Sleeve 354ml in navy is a protective insulated cover designed to fit and insulate standard 354 ml cylindrical drinking bottles. Crafted to reduce heat transfer, the sleeve helps keep beverages closer to their original temperature while protecting the bottle surface from scratches and minor impacts. Its slim, lightweight design makes it easy to carry in bags, backpacks or by hand for daily commutes, travel and outdoor activities.

Advantages

The sleeve provides thermal insulation that limits temperature exchange between the bottle contents and the external environment, helping to maintain drink temperature for longer periods. The snug fit prevents unwanted movement of the bottle inside the cover and reduces surface scuffs. The navy fabric finish offers a neutral appearance that resists visible dirt and complements a range of bottle styles. The lightweight construction adds minimal bulk and does not significantly increase carrying weight.

How to use

Slide the thermal sleeve onto a clean, dry 354 ml cylindrical bottle until it fits snugly around the bottle body. Ensure the sleeve does not obstruct the bottle opening or cap mechanism. For best thermal performance, place the beverage in the bottle at the desired temperature before fitting the sleeve. Remove the sleeve when washing the bottle or if the cover becomes wet; allow both sleeve and bottle to dry completely before reassembly.

Usage recommendations

Hand wash the sleeve with mild detergent and air dry to preserve the insulating material and fabric finish. Avoid machine washing, tumble drying or exposing the sleeve to open flame or high heat sources. Store the sleeve loosely when not in use to retain shape and insulating properties.
