Your winters just got a whole lot warmer with a cycling jacket that's made to impress.

When the weather takes a turn for the worse, don't bother uncrumpling your ratty old jacket that barely keeps out the cold. Get incredible dry-weather breathability and comfort with an unbelievably high level of water protection with the Castelli Men's Alpha RoS 2 Jacket, and never settle for less.

A double-layer construction allows you to utilize the impressive outer wind-protection layer while keeping the insulation layer closed, allowing airflow inside the jacket to eradicate moisture while avoiding direct contact with the skin. On a long climb, a smart cyclist will completely open the outer layer to allow moisture to escape, and zip up that outer layer during a descent to remain completely dry inside. Water-resistant GORE-TEX INFINIUM™ WINDSTOPPER® fabric is utilized along critical seams around the shoulder to keep you dry through mist, wet roads, and even incessant light rain. Other seams are hidden out of direct water flow and, with the water-repellent treatment on the fabric, moisture is completely prevented from entering.

Featuring the brand new double-layer wrist opening, fit with an inner layer that goes under your glove to seal tight to your wrist, and an outer layer that goes over your glove so rain will roll down the outside of the glove — and not end up inside.

Prepare for your gear to get a cool new upgrade. Every detail in the Castelli Men's Alpha RoS 2 Jacket is designed to let you ride longer and in complete comfort throughout the cold-weather months — making this the ultimate winter jacket.

Features:

  • Rain or Shine engineering makes this our best jacket ever for dry conditions while also providing significant rain protection
  • GORE-TEX INFINIUM™ WINDSTOPPER® 150 fabric for wind protection with high breathability and effective rain protection
  • Reduced seaming with seam sealing on shoulders reduces chances for water to enter through stitching
  • Double-layer Alpha construction separates insulating layer from wind/water barrier to let you better regulate ventilation
  • Water-resistant YKK® Vislon® zipper slides easily for better regulation of airflow
  • Raw-edge waist with silicone gripper lies flat and seals out wind
  • Double-layer cuff integrates with glove to prevent cold wind or water from entering at wrist
  • Stretch fabrics with advanced patterning make for excellent close-to-body fit that still accommodates a wide range of body types
  • Back ventilation rear pockets with reflective laser-cut drain holes
  • Zippered secure side pocket for valuables
  • Heavy-duty 525 grams
  • -5°C - 10°C (23°F - 50°F)

    The best winter jacket
    by Anonymous

    Seattle, WA

    I live in the Northwest and this jacket fails to disappoint, having now used this almost one full winter season. Breathes well, superior wind resistance, and warm. I've ridden in the low 30's with only a mid weight base layer underneath, once when raining and remained dry. Versatile. Love the side zippered pocket for valuables/phone. I've have other name brand winter jackets, but this is by far superior to them. Buy it. You won't be disappointed.

    Excellent Cold Weather Jacket
    by Colnagolover

    I'm 6' 2" and 190lbs and the 2XL fits just right with a medium weight base layer underneath. A base layer thicker would make a tighter fit in the sleeves. The length is satisfactory with a person of my height. The jacket is form fitting. The dual sleeve at the cuff makes for an air tight fit with gloves and is a great addition. I've worn the jacket at temps from 3C to 6C and it is almost too warm. With a medium base layer it should be comfortable down to -3C to -6C. The zipper is more robust that on similar Gore jackets and has a zipper flap to help seal out air and comes with a long tie which helps when wearing gloves. I expect the jacket to last quite a few seasons. Having a winter jacket with three back pockets is a definite plus.

    Amazing piece of kit

    Very versatile. I have been comfortable at 45F with a sleeveless base layer and in the mid 20s with long sleeved merino wool base, and have no doubt I would stay cosy at even lower temps. Also very comfortable and a more racy fit than most winter jacket which I like. Finally sleeves are nice and long, avoiding the dreaded gap (something is a problem with the Castelli Espresso that I got a couple of yrs back).

    Only "issue" is the color fiery red is close to orange - something that it is hard to tell from a website picture.

    A great jacket for cold days
    by Anonymous

    This is a great jacket. It has kept me warm down into the 30s Fahrenheit. I have not yet tested it in the rain or snow. My arms have gotten chilly when not wearing a long sleeve base layer, but with a base layer it has been all I have needed.

    Quality made product. European fit. Means it's tight. But right. Refer to Castelli size chart. Performs as described.
