Cool to cold, primarily dry conditions when light weight and breathabiliy are the priority.


Using the latest and most advanced version of Polartec’s renowned Alpha insulation, by adding merino wool, the Alpha Merino Air jacket punches way above its weight in terms of warmth, breathability and performance. Alpha Wool is used as interior insulation on the sleeve, front and collar, while Pertex Quantum Air provides an ultralight wind and water resistant barrier to help trap heat while maintaining class-leading breathability. The back panel of the jacket is made from fleece-backed italian milled recycled polyester to aid in breathability and mobility.

Likely our most technical riding jacket ever, the Alpha Merino Air uses our proprietary 3D patterning and carefully engineered on-bike fit for a super streamlined fit and covering a wide range of temps and conditions.

"Velocio's Alpha Merino Air Jacket might just be the best winter jacket we have tried."
- Dan Chabanov, Bicycling

  • 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:

  • Find your weight along the top of the table.
  • Look down the column to find your appropriate size.
  • Each size has a height range based on weight.
  • If you find that you are on the upper or lower end of height and weight for a given size, the garment will have more or less compression respectively.
  • Use the Dimensions Details chart to further dial in your fit.

    INCREDIBLY warm! I can finally ride in the cold!

    To start off- I run very cold, and because of this, winter riding is usually a no-go for me. I got this jacket after hearing great reviews, and can't believe how warm it kept me, without needing to layer. I rode in 35 degree weather no problem, without even a mid-layer! I even got caught in the rain and the water resistance held up plenty long enough for me to get home. So happy with this jacket, and the fire red is a gorgeous and highly-visible color! So excited to be able to keep riding throughout the winter, and without needing to reduce my mobility in tons of layers. I can't recommend this enough!

    The best!

    This is simply the best winter cycling jacket I’ve tried. It’s crazy warm, with only a base layer underneath. The fit is also perfect and it is so lightweight. The only improvements I could imagine would be to add ‘pit zips’ for extra ventilation on climbs or on days when it’s over 40°, and to include a small zippered pocket for valuables.

    Bring on the cold weather!

    Winter cycling is one of my favorites. And it just got infinitely better with my Alpha merino air jacket. I'll admit I was a bit nervous going out in just a base layer under it. I decided to give the jacket a go as it’s meant to be worn on a recent cold day (packing an extra windbreaker for backup.) At mile 4, I was taking off the neck gator I thought I would also need. I was toasty warm and the mobility gained with reduced layers is fantastic! Wearing is believing!

    Great Jacket!

    This jacket is surprisingly warm for its weight, even in the low-mid 30's I found it warm enough with a single base layer underneath. It feels like you're wearing a long-sleeve jersey. However, it also breathes well and allows much more mobility than other winter jackets I've worn in the past. Absolutely no complaints, would highly recommend!
