Flip Top Flask
Keeps your drink hot when it's cold outside and cold when it isn't.

Double walled, vacuum insulated stainless steel holds temperature for hours and handles the knocks of an active outdoor life without fuss. Leak proof, durable and refillable, a simple step away from single use cups.

Questions, answered.
How much is delivery?
Free tracked UK delivery on orders over £60, so it ships free with any robe. Your estimated delivery date is shown under Add to cart.
How long does it keep drinks hot?
Hot for 6 hours, cold for 8 and iced for 30. It's double-walled, vacuum-insulated stainless steel, so your post-swim drink is still hot when you're dressed.
Can it go in the dishwasher?
No — hand wash only, and dry it fully before storing. Don't put it in the microwave.
Will it leak in my bag?
The flip-top seals tight, so you can throw it in the bag with your wet kit and nothing ends up in your towel.
What's your return policy and guarantee?
Two things, so you're covered either way.
60-day free returns on unworn items. Taken it out for a session and it's still not right? Get in touch anyway.
