The Giordana Sport Vintage Merino Wool Short Sleeve Jersey is a hybrid of our own heritage and style combined with a modern spin on wool fabric. All About The Fabric. The entire jersey is constructed of polyester/Merino wool blend fabric which is soft against the skin, breathable, and keeps the body cool or warm depending on the temperature, as only natural wool fibers can. A fabric like this is necessary to get maximum performance out of a jersey that isn’t designed to have a skin tight fit. That’s right, this jersey is designed to have a more casual relaxed fit, utilizing minimalistic paneling that harkens back to the days of wool jerseys and steel frames. The fabric also provides UV protection and antibacterial properties. Rich Details. The rich details of the jersey include zippered pullover design, three rear pockets with contrasting color bar tacks, Giordana shield patch logo, elastic free sleeve cuffs with accent color, light elastic at the hem featuring the original Giordana Sport Made in Italy fabric tag, and flocked vintage logos.
