Wind jackets are four-season items, in our opinion. When done right, they're a thin, stowable exterior layer that extends the temperature range of your clothing. On a summer afternoon, it's enough to ward off an evening chill or give you some protection from cool air after summiting a 2,500-meter peak for the drop back to earth. On a winter morning, it can go over a thermal jersey until your body is warmed up or the thermometer has started reaching upward. The Triseason Wind Jacket from Giordana is, despite the name, a four-season jacket.The jacket is made from Giordana's Sentry Light material. It's similar to their waterproof Sentry fabric, but thinner, lighter (a mere 35g per square meter), and more breathable. That doesn't mean it can't be used as a rain jacket, just as one that can keep light drizzles at bay (doesn't have taped seams, doesn't have the extra membrane), and will remain windproof when it's wet. There's a school of thought that when riding hard, the extra breathability of a wind jacket is preferable, as you're less likely to overheat. The jacket, beyond its material selection, vents by design. There are exhaust vents on the shoulders, and the front zipper has a rubberized pulltab that is there to remind you to adjust the zipper as necessary. The jacket is finished with light elastic at the wrists and waist, along with Ametista stretch hip panels that keep the jacket on your body and not flapping around. There are also reflective strips sewn into seams behind the neck and alongside the hips for better visibility. There's a tiny pocket in the inside back that doubles as a stuff sack. Look closely at the White version from the back and you can see it under the Giordana logo. The Giordana Triseason Wind Jacket comes in Black and White. The Giordana logos are made of rubber and stitched onto the garment. Sizes run from Small to XXX-Large.
