The standard mouth Hydroflask has a new trick up its sleeve in the form of an insulated sports cap, we put it to the test
hydroflask 18 oz with sports cap
Overall Score
Sports cap makes it oh so versatile
Heavier than plastic alternatives

Hydroflask make their flasks in a range of sizes and colours, as well as several mouth and lid options. On test is their 18 oz (532ml) insulated flask with the optional sports cap accessory.

Although we love Hydroflask for camping, hiking and travel we wouldn't have normally considered taking one on the bike until we discovered the optional sports cap.

Like the flask with its double-wall 18/8 stainless steel construction., the cap is insulated so your drinks stay cold for up to 24 hours and hot for up to six.

The cap is much more premium than that of your classic cheap-as-chips sports bottle with a soft rubbery teat from which to suckle your chosen beverage from and a very clean but solid interface with the flask itself.

You can chuck the Hydroflask about a bit without worrying about it getting damaged and we think it looks a lot nicer than your standard see through polyethylene effort thanks to a powder coat in a range of nicely judged colours and an overall feel that reminds us of a classic Sigg.

Ok it's heavier and more expensive than the usual cycling alternatives but it's worth it to get a flask that you can fill with your favourite beverage, whether hot or cold, and take on your bike, camping, hiking, travelling, to work or anywhere else you fancy.
