Thermal type bottles often disappoint, but this one certainly doesn't, keeping drinks hot (not warm, hot) for up to 8 hours (I haven't tested beyond that). As far as cold drinks go my only experience is that I put ice cubes inside and they were still solid after 6 hours. Just be wary of the drinking spout with hot drinks, liquid comes out quite quickly and could burn the lips of you're not expecting it.

Wonderful product


During social distancing, it is nice to have a coffee break. Keeps a hot drink for over 3 hours.

Only thermos bike bottle available on the internet, or so it seems. Keeps coffee piping hot for 2 hours. Great product, bit heavy though.

Andy Stock

Bottle works well but after one use in a plastic bottle cage the print starts to come of. Now after a couple of weeks the bottle looks tatty.


Great insulated bottle, keeps the contents warm for a very long time. The sports cap isn't great so I would advise sticking with the insulated one.

Robin Puplett

Best day-to-day bottle I have. Keeps drinks cold seemingly forever and totally bomb proof! Awesome product.


I used for my lovely coffee and the bottle keeper warm for more than 8 hours. Really good product


Submitted the following review on this product 7 days ago. Bought Thermal Deboyo bottles primarily to use on the bike, although the Bottle keeps liquid warm, the “flip” cap for sports (and therefore for use on the bike when cycling) is flimsy and weak and after one use looks worn and ready to snap. Received the following response from SIS, however, no email received from SIS. Please do not respond via Trustpilot telling a customer that you will be in touch “shortly” to discuss the product And then do not contact within 7 days, this is not good customer service. Hi there Mark, I am sorry to hear that you are disappointed with one of our products on this occasion. Thank you for your feedback, we very much appreciate it and will pass it on to the relevant team. We will have a member of the CS team send you an email shortly to discuss this further.
