Don't use with boiling water! – Rating 4

Posted by Jim Duff – 31st Mar 2010

I really like my 2l widepack but I messed it up a bit by putting boiling water in it this winter. Still usable but its gone a bit crinkly. Apart from that, they are really easy to clean because of the wide opening top, which is import if you're using energy drinks.

Make sure you run plenty of warm water through the tube to clean after use too.
