Castelli Fondo 2 Jersey FZ - Military Green/Silver Reflex
(Product No.: CG-4521513.075.MS)
This core layering piece, warm and with a neutral fit and reflective details, is designed to look great whether you use it on its own or under a vest.
- Made from 100% polyester fleece for extra warmth and wicking
- Easy-sliding YKK® Vislon® zipper
- 3 rear pockets
- Silicone gripper elastic at waist
- Large reflective panels on both sleeves and center pocket
We designed this jersey with the idea that you'll wear it half the time on its own and half the time under a vest in cooler conditions. So we made it look great no matter which way you use it. We made it highly functional using our Warmer fabric, which is thickly brushed on the inside, yet the 100% polyester composition means it doesn't hold sweat. The bands on the sleeves and the vertical stripe on the pocket are reflective for low-light visibility.

How to Measure
- Chest: measure horizontally under the arms around the fullest part of the chest.
- Waist: measure horizontally around the natural waistline, keeping the tape slightly loose.
- Hips: measure horizontally around the fullest part of the hips with feet together.
- Inside leg: measure a well-fitting pair of trousers from the crotch seam to the ankle.
- Hand circumference: measure around the hand using a tape measure or a piece of string and a ruler.
- Bra: measure bust at the fullest point and underbust directly below the bust.
Fit: Castelli specialises in performance cycling apparel and many garments have a close-to-body fit. The manufacturer's general rule is to choose the larger size when your measurements fall between two sizes. Product-specific fit guidance always takes priority.
