– Travel Coffee Flask 473 ml (16 oz) - Vacuum Insulated Stainless Steel Travel Mug with Leak Proof Flex Sip Lid - Wide Mouth - Trillium

I've used various insulated coffee mugs over the years and all of them have had the same problem - leaks. Apart from leaks, most other insulated mugs are very large considering the amount of hot or cold drink within. HydroFlask have completely changed the game with this insulted flask as it doesn't leak at all even when you turn it upside down! It also solves the size issue by being very small, more in line with the size of the contents. This also helps it to fit under the spouts of our coffee machine. The good news is that the size isn't at the expense of performance as the contents are kept hot for hours. I've found tea in particular stays hot for a long time. Travelling to a venue to watch some sport and having a hot drink for the duration is absolutely achievable. A points to bear in mind is that assembly and disassembly of the lid section can require some strength and so would not perhaps suit people with strength issues. Also, the red silicone seal needs to be fitted the correct way round (match the lid moulding with the cut outs on the seal) during reassembly as other wise this leak proof flask will leak! Personally, I think this flask is completely worth the cost for the high quality of the item. It's literally a game changer 😀

Best coffee flask I've bought to date. No leaks, and easy to carry. I have a pile of useless travel cups in the cupboard. This is the first one I've been able to consistently use. It's easy to wash as the lid comes apart. It also keeps my drink hot for hours which is handy when you work in the NHS as I never get to finish a cup of tea. Highly recommend.

Decent water bottle, fits in my new Loungefly, doesn't leak, had hot chocolate in here and it didn't cool down, I would say it’s worth the price 👍

Great product..like the twist top opening and carry handle . Keeps liquids warm for some time

Bought this for hiking as my camelbak cup handle broke and they don’t make replacements and I wanted a cup that was completely dishwasher safe. Fab colour, bit fiddly to take apart completely but I’ve been impressed with how long it keeps hot drinks warm, and cold drinks cold. It fits in the side pocket of my osprey bag for easy-ish retrieval. Really impressed and glad I purchased.

Good size , keeps coffee hot but leaks constantly if tipped

Good quality and keeps things cold or hot for much of the day. At least 4-6 hours without issue. However, I haven't had it a year yet and it now frequently leaks badly. Not reliable in the long term.

I have tried many travel mugs and so far this one has been my favourite. Pros: -Leak proof. -Small enough to fit in a bag. -Twist mechanism to open and close the drinking lid. -It does keep the heat retained for a good few hours. Cons: -The lid mechanism does need to be taken apart in order to clean but intructions are clear. I mainly use this for coffee so a quick rinse is enough. I recommend buying this and the brand itself are quality.
