The outer fabric color is light blue. The shoulder strap is made of PP tape, which is resistant to water and friction, and has an adjuster that extends from approximately 55cm to 110cm. When fully extended, it can be worn by adults. The bottom is circular, so I believe it will be less prone to corner scuffing that can occur with square gussets. The inside is quilted to protect the water bottle. It will protect against dents and scratches even if the water bottle is dropped. It has been pre-washed, so there is no shrinkage after washing, and it is also durable for washing. This is a handmade item made by an amateur. There may be some distortions or double stitching, so please only purchase if you understand and appreciate handmade items. This is a finished product, so you can purchase it immediately. The price is set for a finished product. Water bottle Water bottle cover Entrance Admission Thermos Thermos 600 Dinosaur Blue #MaiiaMfinishedproducts
