Mr.B's insulated Coolclip thermal bottle and meal bag is the cleanest, and safest, and most modern bottle and meal storage bag you can buy. Lining is 100% waterproof with no stitching on the inside seams. Lined with Ultra-safe PEVA material (no PVC linings like many leading manufacturers make their bags with – don't be fooled). PEVA material is stain resistant and wipes clean every time. Long adjustable top strap with sturdy snap-buckle is designed for you to find a comfortable way to clip the bag onto the side of a stroller or adjust to use as a carrying handle. Bag is also supplied with a full length adjustable snap-in shoulder strap so you can wear it on your body or sling the bag over the back of a stroller. Rounded ergo shape is super easy to slip in and out of a toddlers back pack. Top loading zipper lid means that even if there is a spill in the bag the likely hood of a leak is minimized.
