CAMELBAK CRUX 3.0L RESERVOIR £40

Hot because: The Crux replaces the Antidote Reservoir at the core of CamelBak’s hands-free hydration systems. They claim that it supplies ‘20% more water per sip’ than the Antidote through its Big Bite valve (which includes a satisfyingly chunky on-off lever). But users are equally likely to appreciate the new cap and opening (the widest on the market, apparently), which makes filling and – just as importantly of course – cleaning and drying the reservoir significantly easier. We say: The industry leader – new and improved for 2017. www.camelbak.com
