I've been hesitant to buy this jersey due to cost but with a big ultra ride coming up this year every piece of kit is critical. There is a reason the Gabba is the standard for tough weather conditions. This jersey has been great for my winter training rides. The Gabba, a merino base layer, along with arm warmers has been fantastic for cold mornings with drizzle. Once the day warms a little the arm warmers come off and I'm good to go. Great jersey!
