Let's keep pushing to ban all those plastic bags - which are literally killing our planet. Buy a Blu Bag or two and feel good knowing a portion of the sale is donated to support the Ocean Conservancy. These lightweight bags are 100% polyester and machine washable. They measure 19" x 24" and hold up to 50 lbs! Easy to take along since it rolls right up into its own carrying pouch that has a carabiner clip. They also make great, thoughtful gifts!
