Look great

Outstanding heat retention!

I bloody love this flask.

Firstly, it doesnt leak - you can throw it around, turn it upside down. It's got a great seal.

Secondly, it has a great lid with two simple steps to take apart and clean. This seems a robust and hard wearing mechanism, that's simple.
(I bought another brand prior, and took it apart, leaked ever since - this does not!)

Thirdly, last night at just before 10pm i made a cup of tea in it as I am staying away from home.
Fell asleep before I'd even made a start on it and at 8.15am this morning it was still hot!

And finally, it feels nice to hold, slight texture on the sleeve makes it easy to hold and not slippery (I drop things a lot!)

Absolutely worth the price!!

Also I would like to mention how great Sea and Stream are with delivery and returns as I have used them for several items.

Brilliant flask

I absolutely love this mug. Mostly as it is genuinely leakproof; I can chuck it in my pannier for bike/swims and not a drop escapes. It replaced one that claimed the same protection and lied! Alternatively, if I’m walking I can use a clip with the handle to keep it handy on the outside of a rucksack.
It’s mildly depressing (and shows my age?!) that I also like the fact it easily comes completely apart for cleaning (so hot chocolate is an option 🙂). It feels really robust, is the perfect size and a great colour (a welcome bright spot on some grey days), it should be the last one ever need.
Not the best pic I’m afraid, cold hands!

What I really wanted to say was how impressed I am that the whole package is plastic free, really great to see and wish more would follow your lead.
