Castelli Cold Days 2nd Layer Womens Long Sleeve Base Layer
This Womens Long Sleeve Base Layer by Castelli is ideal for freezing cold days, and makes an ideal 2nd layer, over a base layer. Polartec® Alpha® 90 high-loft active insulation is key to the warmth, and is soft, stretchy and breathable while keeping weight to a minimum.
The half zip keeps bulk down while still allowing some adjustment, and it's slightly offset so doesn't clash with zips on other garments. A high collar prevents draughts, and the base layer has a close-to-body fit that can be tucked into a pair of tights or worn over the top.
Features
- Polartec® Alpha® 90 fabric high-loft active insulation made from recycled PET
- Maximum breathability
- Asymmetrical zip
- High collar

If you're unfamiliar with your Castelli size, we recommend you go up one size to obtain the best fit possible. Note that you do not need to size up for the jackets or vests, please select your normal jersey size.
Castelli clothing is designed for its intended use and should be comfortable when on your bike in a riding position. Your garment should be snug to provide you with moisture-wicking capabilities, as an aerodynamic aid and prevent any fabric from flapping in the wind.
If you require any advice on Castelli sizing, please do not hesitate to contact us.

About Castelli
At the front since 1876.
Castelli has been at the front of cycling apparel since 1876, founded in Milan as the original maker of pro race kit. From the first cycling jerseys to today's WorldTour-proven aero garments, the brand has spent nearly 150 years putting innovation onto the backs of the fastest riders in the world.
Castelli outfitted the first organised cycling teams in Italy and has been a constant presence in the pro peloton ever since. The Scorpion logo appears on more WorldTour podiums than almost any other apparel mark.
