Pro team insulated gilet, size L. In winter, wearing a fully insulated jacket can lead to overheating on climbs, forcing you to take it off. A gilet allows for easy temperature adjustment with its zipper. It has a double zipper, allowing you to open it from the bottom as well. The side panels are stretchy, but the front and upper 2/3 of the back are overlaid with Polartec material, making the chest width roomier than a standard lightweight gilet. With a chest width of 56cm, it should be suitable for mid-winter in the city when worn over a long-sleeved, mid-weight jersey. It's also recommended as a complete insulation layer under a windbreaker. I purchased this but found the chest width a bit too large, so I've changed to a smaller size and have only used it once. - Brand: Rapha - Color: Orange/Beige - Style: Sleeveless - Material: Nylon - Features: Zipper - Logo: Rapha Thank you for looking.
