Like the Rapha Stowaway and Pearl Izumi Octane, the CP Storm is a minimalist, straightforward jacket aimed at racing whippets who want a close fit with zero flappage.
All the non-critical features such as draw cords on the neck are absent to keep it light and easy to stuff in a pocket.
There’s a pocket on the rear as well as an inside vent for added airflow when putting the hammer down. This is a good thing, as the Climaproof material isn’t as breathable as some on test.
We like the waterproof elasticated shoulder panels that help with the fit while providing plenty of restriction-free movement. All the seams are sealed, and the natty inner arm cuffs seal things in a simple and light way. The back panel is pleated to expand over a back pack.
Wearing it over a bag improves the average breathability slightly as the back yoke flap still works (although you lose the shirt-to-shell direct wicking effect). The jacket is cut large so we'd advise trying a size down for a snug seal at neck and wrists.
The diagonal asymmetric zip is smooth in use, even when filthy, and the mesh neck and one-handed hem drawstring stop draughts.
The chest logo hides a port for a drink pipe and there's a zipped pocket on the other side for keys, etc.
Weight is impressive at 248g but you've got to really like the bag features and brand for the price.
