(Brand new) Lululemon Back to Life Insulated Water Bottle (Black) (32oz / around 1 litre)

This was given to me as a gift so it's brand new. Retail price for this size is currently £48.

32oz is just shy of 1 litre, which is a good amount of water for one person during hot summer days. 

The insultation is pretty good on Lulu bottles - they can keep ice water cold for almost the whole day especially the wide opening allow you to use slightly bigger ice cubes.
