Plus, it’s made with Honeycomb Insulation™ to keep drinks cold up to 24 hours or hot up to 12 — no matter what the weather’s doing outside.


  • Compatible with all Wide Mouth bottles
  • Honeycomb Insulation™ helps keep cold drinks cold and hot drinks hot
  • Durable, stainless steel pivots allow the strap to move easily
  • BPA-Free and Phthalate-Free

Care & Cleaning

  • All Hydro Flask caps and lids are top rack dishwasher safe. If you prefer handwashing, we recommend warm soapy water and a Hydro Flask Straw and Lid Cleaning Set. If scrubbing is not your thing and a dishwasher is out of the question, our Natural Cleaning Tablets are a great natural way to clean your bottle accessories with almost no effort. Just fill a bowl with warm water, add your items (disassemble if needed), and drop in one tablet per 32 ounces of water. Let stand for 15 - 30 minutes and rinse.
