How often do you do that though on a typical road ride. Maybe if I was doing some long cycle tour, but for most rides of a couple of hours or so I’d never bother (other than maybe taking off arm warmers) but then I hate stopping on a ride.
That’s the great thing about the Gabba. Seems to cope with a decent variety of spring/autumn conditions without getting too hot or cold, and can cope with a bit of a shower without getting too wet and cold. Means you can get away without taking layers to put on and take off as conditions change. Remember a ride earlier this spring where it started out relatively warm and sunny, then halfway through the ride the wind picked up, got chilly and started to tip it down, a bit of hail too, then brightened up and got warm again. My Gabba with a thin base and some Sportful NoRain bibs kept me comfortable all ride.
Anyway, in answer to your question, probably a Gabba 🙂
