EXTENDED COMFORT RANGE
This is our most refined windproof base layer yet. We’ve improved the stretch and breathability of our SG0.6 Wind fabric, and dialed in the fit perfectly. We like to use it on those cool days that aren’t quite enough to pull out the winter gear yet.

• SG0.6 windproof fabric on front provides weightless wind protection
• Smooth shoulder layering
• Perfect for riding in cool, windy conditions
