At Alpha Designs we focus on function over form without compromising on design. So we went back to the drawing board and developed the ultimate water bottle. The Alpha Bottle XL is made from FDA approved 100% food-safe PET plastic, unlike a lot of similar bottles on the market. The Alpha Bottle XL features a silicone seal which ensures the Alpha Bottle XL is 100% leak-proof, combined with a heavy duty rubber strap and it’s huge 1600ml capacity, the Alpha Bottle XL is the ultimate accessory to keep you hydrated. Grab the ultimate accessory for your Alpha Bottle with one of our high quality Alpha Armour neoprene bottle sleeves! The high quality neoprene keeps your bottle condensation free, your drinks cool and also protects your bottle from some of the knocks and bangs that can happen with everyday use.
