## Description

ThermoFlask 40 oz Double Wall Vacuum Insulated Stainless Steel 2-Pack of Drink Water Bottles, Midnight/Stone

Review: Really useful bottles - Having just done a review of the wide mouth replacement lids (that you suck through rather than pour) felt it necessary to review the bottles themselves. Bought my first pair at Costco and they were so so useful tried to get two more but Costco don't do then now so tried and succeded with desertcart UK. More robust than plastic bottles and keep the water really cool. I use my for squash as plain water not to my liking but you do need to wash out bottle and lid frequently as the squash can leave residue which will tiant the taste, especially black currant and apple.
Review: Hits the spot - Bought this for my son to take to school, we have been using on trips outside home all summer. I took off the straw, and it works perfectly well and maintains the temperature for a good 5-6 hours. Easy to clean, easy to use and the lids are interchangeable. What’s not to like!
