Since receiving the Giro Insulated Vest, it’s become a staple layer for me on both city and mountain bike rides. Even when I wasn’t wearing the vest I carried it along, as its small pack size makes it a great option for these days of unpredictable weather.
The vest is nylon with a water-repellent finish and a very light, synthetic insulation. On high exertion rides, I wore it in mid-30 to mid-40 degree temps with a wool baselayer and into the 50’s for everyday hanging out. Overall, it only adds about a quarter-inch of thickness, but considerable core warmth, and its close-fitting nature makes the vest a great layering piece. When temps dropped below 35 degrees I layered it under a lightweight jacket. A grippy front zipper makes it easy to take the vest on and off with gloves on.
All of the exterior pockets—two front hand pockets and a rear pocket—have low-profile zippers, which are integrated in the vest’s side panel construction. The rear pocket is accessible from both sides of the jacket and is compartmentalized into three smaller pockets within a full, mesh back lining. This allows you to use the vest zippers for ventilation without losing anything from the pockets.
While $160 is a bit of an investment, the Giro insulated vest is a well-constructed and versatile piece that I’ll wear for years to come. giro.com
