## Description

Durable stainless steel travel mug keeps beverages hot or cold for hours. Leak-proof lid, easy-grip design, and fits most cup holders for on-the-go convenience.

Review: Outstanding and no leaks! - 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 😀
Review: Great product.. - Better than my Stanley thermal cup!! Last longer hot, easy to clean even with more items in the lid to dismantle than my Stanley cup. I'll be purchasing another and removing the Stanley cup in the near future.

### ⭐⭐⭐⭐⭐ No leaks, keeps drinks hot and looks great.
*by E***A on 15 October 2025*

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.
