With feedback and testing throughout the harsh winter months, 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.
Our jerseys and bib shorts are intended to be form fit, providing compressive support, maximizing performance of the fabrics, and reducing fatigue and chafing. Due to the compressive nature of the fabrics, you will be able to fit into more than one size. Please use the charts below to help determine your optimum size:

I love the alpha long sleeve! first it is a great piece to look at and performs as well as it looks. I had searched for something that is warm but not hot and this has wool in it which is one of my favorite material to ride in. Can’t wait to wear it as an outside layer. I hope you make more pieces similar to this. Maybe to work as a ride or off bike piece.
Finally got an alpha base layer, well worth the wait. This one of the warmest base layers I have worn, it really is worth the price. Can't wait to try it in colder weather.
Fit was true to size. This is a great layer for cool to cold weather.
Best piece of gear for Colorado winter weather. Use this with many jackets for various conditions (snow, rain, cool, or cold).
I live in MN. The alpha jersey under the shell jacket is perfect for cold winter days.
