I took advantage of Rapha's deal on a 3 pack of merino wool base layers. In the past I've been using synthetic base layers, and they did there job. Kept me warm in cool weather, but when it got hot it was not the business. Come in merino wool base layers. One word: TRUTH. It regulated my body temperature by adding warmth when it was cool but not so much to overheat me when it warmed up. It felt like I was wearing nothing and didn't restrict any of my movement. And the most important part, I didn't wreck like ass after the ride. I'll never go back to anything else. Rapha base layers saved my ride.
Drop that extra dough on quality base layers. Don't cry and say it's too expensive when you're dropping money on your bike like you have a golden goose in your backyard. You'll thank me later.
You know the drill. Cop hurrr.
