Review: Keeps cold! - Amazing - keeps cold for ages 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. ## Features - Stay Hydrated All Day: 2-Pack ThermoFlask Stainless Bottles ensure your drinks remain at the ideal temperature with double-wall vacuum insulation.

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.
