Flexiflasks are triple walled and vacuum insulated to keep your drinks cold for over 24 hours or hot for over 12. The outer straw is soft which is gentler on teeth, and the inner straw is stainless steel, mould resistant and easy to clean. In fact, the whole thing is easy to clean, which is a must for all parents, let's face it.
The matte finish is scratch resistant and doesn't get covered in condensation, plus there's a strap to make it easy to carry. There's now NO EXCUSE not to choose to re-use when you're on the go.
Oh - and did I mention leak proof and spill proof? You're welcome.
