Underarm cutaways and extensive mesh sections make this the coolest armour on test. The chest protection is nicely contoured to protect the ribs.The backplate is removable and has routing for a hydration bladder (you can run both if you want). Detach some of the padding and stuff some spares in the two rear pockets and you're ready for a pack-free enduro or big ride, so it's effectively two garments in one.
There's no long-sleeve version, but you can always add a set of elbow pads for extra protection.
