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.

• Caring for your cycling gear properly will extend its life and maintain its performance, fit and quality. It’s important to consider these instructions carefully. While we stand behind the quality of our apparel, not adhering to these instructions will void our warranty against manufacturing & defects.

  We strongly recommend washing your new gear before wearing it. You’ll find that your apparel will soften, and fit & comfort will improve after washing - especially with bibs & shorts.

  Machine wash cool, 86°F (30°C) with like colors: Cooler temps maintain better longevity for your apparel. Like colors, especially lights, will remain more vibrant when washed with like colors.

  Use mild detergent. Do not bleach or dry clean: Strong detergents & bleach can break down the fibers and elastane in the garment, dramatically reducing its life.

  Close all fastenings: this goes also for other garments mixed in with your cycling apparel. Velcro closures or clasps can catch on stitching or trim and damage your garments.

  Lay flat to dry. Do not tumble dry: Do not put your cycling apparel in the dryer. Even on low heat. Don’t do it. Heat can damage fabric, elastic and heat transfer logos very easily. Lycra (Elastane) is used throughout our garments to provide compression and support and is susceptible to damage from heat and can irreparably damage your apparel.
