Lightweight shells are one of the most versatile pieces of clobber around. The Exit's pre-articulated and stretch-panel fit works well on the bike, with its adjustable strapped cuffs and dropped hem to keep draughts out.
The fabric looks and sounds a bit like medicated toilet paper, but it shrugs off wind chill and light showers for a while without soaking you with sweat from the inside.
Pit zips, a full length front zip, fleece collar strip and velcro attached hood also give plenty of ventilation or heat level control. It’s nothing miraculous, but it compares well to most of the plastic bags you get at this price.
It packs down pretty light and small for taking out with you ‘just in case’, and the chest pocket even gets an internal headphone port for your mp3 player. Be warned that the shell suit style tends to be a love or hate splitter though.
