On cold, dry winter days, considering heading out for a bit of real training may not be everyone's cup of tea, but if you are exploring the Double Espresso Jacket, you engage in heartier caffeinated beverages as you contemplate heading out into 25 degree weather. The brisk air and weak sun are calling, and for you to answer you must have the right jacket. The folks at Castelli are all about the right jacket, offering so many you can get lost in the process. Here's the bitter info on the Double Espresso. It is Castelli's warmest jacket for maximum comfort during cold-weather riding. Thanks to the two-layer construction featuring a full GORE-TEX INFINIUM™ WINDSTOPPER® 203 outer layer with a separate fleece inner layer, winter riding has never been so luxuriously warm.

The design team built this jacket to be warm and comfortable in those cold, dry winter conditions. If you are going to suffer on a winter group ride with hearty frenemies, it won't be because your jacket game is weak. Castelli partners with the leader in windblocking flexible textiles to deliver this lightweight, weather proof GORE-TEX INFINIUM™ WINDSTOPPER®203 Stretch fabric. This is supreme windblocking, which keeps the cold out, the heat in, and allows moisture to escape. They layered it over a separate brushed micro fleece insulation layer that holds in heat and releases moisture out to the GORE membrane. The outer fabric is moderately water resistant, and shrugs at light precip or road spray.

The cut is slightly larger so that it moves with you and you can add an extra midlayer for super-cold conditions. The design features built in articulated shoulders for greater ease of movement and a tall, shaped collar to close comfortably around the neck. You have three ample rear pockets plus a secure zippered pocket on the chest for keys or money. Heck if you warm up too much, rear side seam zips allow you regulate manually. The high quality zippers are all from YKK®, and there are even some reflective inserts in the rear so you buddy's bike light can catch you going off the front into the misty dusk.
