CAMELBAK PODIUM ICE
£22.99 (610ml/145g)
This had marginally the best thermal properties of our four cooling bottles, keeping our water colder for longest (7°C-11°C). It has a lockable top that you twist to close, a wide opening and the BPA-free bottle keeps your riding refreshments tasting fresh. It’s easy to squeeze too, and we think its extra cost will be justified on hot summer rides.
