A practical thermal insulation bag will work well during walks and travel. The double thermal insulation layer slows down the cooling/heating process of food or water. It has a detachable strap with adjustable length and practical pockets - the outer zipper will fit the keys, and the inner mesh will keep the bottle in the right place. The inside of the bag is trimmed with a waterproof material. The outer shell of the bag is made of a durable and easy-to-clean fabric. Available in several color variants.
