With feedback and testing of our ZERO HL jacket, we created a two-piece system jacket and mid-layer. This highly versatile combination covers an unmatched temperature and weather range, critical to riding here in New England, where summer rain showers in the 80’s can dip to -15F snow drifts in the dead of winter, we sought to minimize the number of pieces in our closet. Take the guesswork out of finding the ideal combination for the changing seasons with the Alpha System.
Inspired by alpine climbing and ski mountaineering, the Alpha Long Sleeve is designed as a mid-layer piece to extend the range of our jackets. Polartec’s Alpha Direct insulation is placed in strategic areas to maximize warmth without weight. The Alpha creates airspace on all leading panels (sleeves, chest, collar) to trap warm air. This construction allows for exceptional breathability and a quick dry layer through a wide range of temps and dynamic and highly aerobic riding.
The sides, back and lower sleeve are made from our Merino 210 - a merino fleece-backed fabric that’s exceptionally soft, thermoregulating and abrasion resistant thanks to the polyester face. A half zip keeps bulk and weight to a minimum and a slim silhouette allows enough room for a base layer, while fitting trim under the Ultralight Rain or Signature Softshell jackets. Three back pockets promise real storage capacity for long base miles.
