If you're spending all day trying to tackle a FKT of one of those brutal hilly rides with plenty of climbs, you'll want to keep your load minimal and hydration plentiful. Look no further than the Evoc CC 2L Plus 2L Bladder Hydration Pack, which offers the space for hydration (included), a tube, and a multi-tool, and nothing you don't. This compact pack is lightweight, adding less than a pound to your ride weight, and comes with a 2-liter bladder for instant use right out of the box. For those ultra-demanding days, the CC 2L expands to hold the 2-liter included Evoc bladder, which is designed with a full-slide top for fast and easy filling.
