Standard Mouth Flex Cap

Your water bottle's original cap could be anywhere from Acadia to Yosemite, and instead of searching every rock on each peak, you're going to opt for Hydro Flask's Standard Mouth Flex Cap. Its stainless steel construction includes Honeycomb insulation to help you drinks stay cold or hot longer. The flexible loop is durable and convenient for hikes and bikes to summer concerts.

  • Water bottle cap fits Hydro Flask Standard bottles
  • Stainless steel construction with Honeycomb insulation
  • Flexible loop ideal for outdoorsy adventures


  • Familiarity: I've put it through the wringer

I got this lid as a replacement to one of my hydroflasks. The handle makes it even more portable for me. I carry it everywhere now.

Better than the last ones.

  • Familiarity: I've put it through the wringer

I really like the new caps. The old caps were made from a rigid plastic that seems to be brittle and had a fixed loop on the top. The new plastic is flexible and the loop on top is as well.

Great Handle!

  • Familiarity: I've put it through the wringer

I like the flex handle on this a lot. It's a bit easier to carry around than the traditional cap and gives you a little extra room to clip it to your pack with a carabiner. This cap fits standard mouth hydro flasks only (the smaller lid).
