      What is the Sport Berkey Water Bottle made of?

      Made of safe, non-leaching, and BPA/BPS-free LDPE.

      The Sport Berkey Water Bottle is made of safe, non-leaching, BPA/BPS-free low-density polyethylene (LDPE recycle code #4).

      • The cap is made of high-density polyethylene (HDPE recycle code #2).
      • The straw is made of polypropylene (recycle code #5). 
      • LDPE is used for the bottle for its "squeeze" properties. LDPE (Low-density polyethylene) is a very effective moisture barrier and is widely used for bread bags, trash/leaf bags, mustard and honey bottles, frozen food bags, tote bags, clothing, furniture, dry cleaning bags, and carpet.

      The number on the bottom of the bottle is not to be confused with the recycle code. The bottom of the bottle will be labeled with the die-cast (molding) number. This will vary from 1 to 4.
