It was the pros who first asked for a Gabba that’s not as hot as the Gabba but warmer than the Fawesome Vest. So we started from the Gabba and made the back in Nano Light fabric — the same fabric as our Nano Flex tights but without the brushed fleece inside. This gives the piece a lot of breathability and keeps you from overheating inside. We further lightened it up by using a lighter weight of Windstopper® (a full 25% lighter than the one used on the Gabba) on the front.
