Innovative Lining Material:The soft villi lining of this insulated bag and soft cooler bag is full of densely-packed villi, forming numerous air pockets. These pockets have low thermal conductivity, effectively blocking heat transfer. They stop warm air inside from escaping and cold air outside from getting in, keeping bottle temperatures stable. The soft villi also protect bottles from scratches, preventing potential bacterial growth. As a bottle cooler bag and cooler bag insulated, it ensures the contents stay at the right temperature for hours.
Multi - Layer Insulating Structure:Besides the villi, this portable cooler bag has a multi - layer setup. The outer layer uses a heat - reflecting material with metallic elements, which reflects a lot of incoming heat. An inner high-density foam or insulating polymer layer further reduces heat transfer. This multi - layer design makes it an excellent keep cool bag, maintaining the appropriate temperature for an extended period. 

Robust Oxford Fabric:Made of high - quality Oxford fabric, this UV Resistant Cooler Bag is not only durable but also tough. Its tightly - woven fibers endow it with high tensile strength, enabling it to resist abrasions from daily use such as rubbing in a stroller basket. Treated with advanced UV - resistant dyes, the fabric of this UV Resistant Cooler Bag can effectively block the sun's harmful rays. This not only ensures that the bag doesn't fade in the sun but also helps in maintaining its insulating properties, keeping its look and functionality intact for a long time.
Waterproof Details:The waterproof zipper has an interlocking mechanism to stop water seepage and is corrosion - resistant. The seams are sealed with waterproof adhesive. This keeps the bottles safe from rain or spills. For those interested in a custom insulated bag, we offer various Oxford fabric colors and patterns, maintaining durability and waterproofing.
