The best beach bottle ever

Just received this email (un-edited) from a friend on holiday (by the way can you guess what his business is called?).

"Chilled water added at 10am is still chilled at 5pm in 38c. Astounding and perfect for beachside hydration. Make up what you'd like with those facts and sentiments.  Will try for better photo using better model.

Seriously Mike this is a great bottle - but you know that."
