Late fall or early spring weather can be unpredictable, and sometimes it's these transitional days that are the most difficult to dress for. The De Marchi Contour Light Transitional Long Sleeve Jersey is made expressly for layering so that you'll have a modular system that can accommodate a wide temperature swing as the day progresses and you tick away the miles.The Contour Light Transitional Jersey is lighter than their Contour Plus Insulator Jersey. For this reason, it's sometimes a better layering piece. On its own you can expect it to be comfortable between 65? to 72? F (18? to 22? C). Of course, this can vary depending on your preferences and whether or not you wear a base layer underneath it. The tight knit is stretchy and light so it's comfortable, and it has a smooth finish so it won't snag as you pull on a jacket over the top. De Marchi employs their Dry3+ Extreme Titanium polyester fabric because it has excellent wicking properties and dries so quickly. It's perfect for rolling terrain that has you alternately sweating up the climbs to coast down the other side in a cold breeze. It has a titanium dioxide finish that works to combat the buildup of odors. The panels are cut to provide a form conscious fit. You'll appreciate this when you spend the day bent forward in the drops and you won't hear or feel the jersey flapping in the breeze.The De Marchi Contour Light Transitional Long Sleeve Jersey is available in five sizes from small to XX-Large and in two colors -- Black and Red. It has three patch pockets on the back and one zippered pocket to keep essential items from bouncing out.
