Training or simply logging miles in the shoulder seasons can be a real pleasure and valuable for year round fitness. Pearl Izumi offers some great products for every season, but there seems to be a true knack for shoulder season apparel from the Colorado-based company. Make the most of the shorter days of the year with their well-designed apparel system. The Interval AmFIB® Lite Jacket provides the warmth you need to enjoy cold weather rides. The designers employ Pearl's three-layer windproof, water-resistant AmFIB softshell fabric on the chest and the leading edges of the arms to shield you from biting headwinds. Thermal fleece fabric on the back of this jacket balances insulation with breathability, so you can ride in comfort without chilly sweat build up. Tune this jacket's warmth to suit the days conditions by adding a light or heavyweight base layer underneath. A zippered chest pocket holds essentials and three bellowed rear pockets are large enough for winter gloves, a neck gaiter and other cold-weather gear. It is a must have piece for enjoying the cycling experience beyond the summer.
