Combining a base layer with a 2.1-litre drinking bladder, CamelBak’s Racebak is a highly effective way of taking ﬂuids on board while riding.
The vest's close ﬁt gives the pack a more natural feel than other drinking systems – which simply hang from straps on your back – while the Quickwick fabric helps take the sweat away from your skin.
The drinking tube hangs down in front of your chest but is easy to grasp and provides constant, convenient hydration through the blue Big Bite valve.
And as well as keeping you hydrated, the Racebak has another advantage: it reduces air disturbance around your back for an aerodynamic beneﬁt. Result.
