Product Description

The goal when Castelli started work on the ROS Alpha Jacket was to create a winter jacket that is good as it can be for cold days. A jacket offering supreme comfort and breathability, a jacket that can adapt to changing temperatures and conditions.

Additionally, they wanted a jacket that if you did get caught in a heavy shower or the day turned for the worst, you would make it back home warm and mainly dry. A jacket designed for winter riders with you not having to take a cape out with you. As close to a one box solution as modern fabrics and technologies allow.

 

Please NOTE. The Castelli ROS Jacket is not intended to replace a full shell jacket for prolonged heavy rain. It’s a bit like the way a Gabba works (on warmer days) so for 90% of the time it’s all you will ever need this winter. And for nearly every cyclist that is enough.

 

ROS - Rain or Shine engineering provides insulation and breathability for cold dry conditions with great protection during wet rides.

 

The Castelli Alpha Jacket is the perfect UK winter jacket for most riders, with great weather protection and adaptable insulation & ventilation. It’s not fully waterproof but do you need it to be?

  • Articulated Collar for better fit

Windproof Jackets Guide

 

Windproof Jackets Guide

When the mercury drops most people turn to putting to layering up to keep warm. However, when you’re cycling the last thing you want is to feel like the Michelin man, bound up, inflexible and uncomfortable. As you ride you’ll get warm very quickly, wearing all those layers will make you sweaty.

Why not choose a windproof cycling jacket instead? They’re ideal for cold dry winter days with most offering some type of light rain protection as well. Windproof jackets tend to be lighter than a waterproof model and are much more breathable.

You can also check out our waterproof cycling jacket guide if you’re planning to ride in the rain. By the end of our windproof cycling guide, you should have all the info you need to buy the right jacket.


Types of Windproof Jacket

Packable Windproof Jacket
| Spring & Autumn

For cool rather than cold rides, a packable windproof jacket may be all you need to keep the chill off. These jackets are very lightweight and are usually made of a single layer of fabric. They’re only a simple barrier between your skin and the elements.

However, these jackets usually have good breathability to stop you from feeling clammy on the inside. Even if it rains, a packable will dry quickly. Most can be rolled up into a small package and will fit in a spare jersey pocket.

Lightweight windproof jacket

Softshell Windproof Jacket
| Spring, Autumn & Winter

Softshell windproof jackets have been gaining popularity for a few years now. They’re heavier than a packable to block more wind and are smooth against your skin for a comfortable feel.

Softshell jackets can be worn over a base layer or a jersey on colder rides without the need for multiple layers to keep you warm. Many are treated with water resistance for light rain protection making them a practical jacket for a wide range of UK riding conditions. You can also pair a softshell with a lightweight packable waterproof jacket for maximum protection.

Fabric

The fabric is key to performance. Generally, the more you spend on a jacket the lighter and thinner the fabric will be. Breathability will improve as well, letting your sweat evaporate quickly.

Gore Windstopper is popular fabric laminating a lightweight membrane to the fabric. It’s designed to keep the wind out and will also help shed light rain too.

Other systems will include an inner lining, middle windproof membrane and then the outer layer, usually treated with DWR water repellency. This design keeps the wind out while staying breathable.

We’ve put together a technical fabric guide for clothing detailing the key fabrics from some of the biggest brands in the industry.

Gore Windstopper Jacket

Fit

Windproof jackets come in many styles, so choose the type best suited to your riding. If you plan on training or racing, then a tighter fit with minimal excess fabric will help prevent drag as you ride.

If you’re commuting or riding off-road then a loose cut with more freedom of movement is a good option.
