Take a short-sleeved Gabba and add removable sleeves, and you end up with quite possibly the only jacket you need; the Castelli Gabba 2 Wind/Rain Convertible Jacket. Severe cold? Put a thermal jersey underneath and go. Cool conditions? Just use a Flanders base layer and go. Rain? Just put it on and go. Moderate conditions? Zip off the sleeves, throw on some nano flex arm warmers and go. Castelli have improved it for Winter 2014 with the updates from the short-sleeved Gabba plus an improved closure around the removable sleeves.
