Rocksolid guarantee

Shop with confidence. If it’s not working out, you can return it (consumables, electronics, undergarments and swimwear excluded).
Really. If it's not up to snuff after you use it (a couple times) you can still bring it back. It lasts longer than 30 days, but not forever. We'll be fair about it.


On its own, paired with a vest, or layered under a shell, this thermal jersey has the versatility to keep you warm on chilly rides, and downright frigid rides. Constructed from a lightweight microfleece with a smooth outer layer and soft, wicking inner layer, the Sinergia 2 is a solid addition to your cold weather kit.

  • Warm and wicking microfleece has a supple stretch
  • 3 rear drop-in pockets for a familiar jersey layout
  • Reflective details help keep you seen
  • YKK® Vislon® zipper rolls smoothly, even after hours of being peppered with road grit
  • Trim fit stays close to the body while still leaving room to layer
