Damian Hall gives the verdict
The Hurricane by Compressport is a pleasingly light windshirt, similar to the New Balance option (see here), but aimed at racing on trails (hence no effort at visibility), and with more features.
The 3D Back Extensor is a great concept. It’s a panel of stretchy material, designed so you can pop the jacket on over a pack, rather than stopping to faff about and get cold. The back panel is really breathable, too.
The main zip is slightly diagonal, so designed apparently to improve freedom of movement. Thumb loops are welcome and the hood has a peak of sorts and good adjustability. Two things let it down. The pocket at the back means your keys or phone are constantly bouncing into your rear end. And do we really need the manufacturer’s name emblazoned all the way down the arm?
Shouty design and an odd pocket, but a super lightweight, clever windshirt for racing.
