SKY RIDERS' FAVORITE JERSEY? Team Sky riders asked for a mid-weight jersey for training and racing in cool weather. We worked hard to find that balance between warmth, moisture management and comfort. We just happened to make this great aero-fitting jersey that's insanely comfortable and instantly became a rider favorite. Wear it with just a base layer on a slightly cool day, or add arm warmers and a vest and you have a super-comfortable outfit for cooler weather. Or even layer it under a Gabba in cold weather. It's a surprisingly versatile addition to your wardrobe.
