Made from Gore-Tex with fully taped seams, the Cosmo keeps out even the heaviest rain.
The fabric is impressively breathable but temperature control comes only from the front zip. This often left us needing to take the jacket off as soon as the rain stopped, and it doesn't pack down small enough to fit in most jersey pockets.
The cut is generous for a bike jacket but a waist draw cord stops it flapping while the effective dropped tail can be clipped inside for non-bike use. You also get elasticated and Velcro'ed cuffs, lots of reflective trim and zipped pockets on the sides, chest and arm.
