We believe the foundation of any good piece of cycling kit is comfort. So we’ve created a collection that puts comfort at its core. The culmination of almost three years of research and development, this collection has become a trusted go-to for multi day endurance athletes and casual cafe spinners alike. Expertly tailored to be comfortably close fitting, these cycling wardrobe staples really are the perfect all-rounders.

“Whether you call it a vest or a gilet, this packable windproof layer is a godsend for spring and autumn when temperatures can vary from hour to hour. The front is made with a lightweight, windproof fabric, allowing warm air to continue circulating around your core. The back is made of a lightweight stretch mesh which helps with ventilation. We also added pockets to make this super functional. It’s a great piece of kit to stick in your jersey pocket and call on when the temperature drops.”

Daniel McClen, Director and CEO at Attacus

    SIZE GUIDEAttacus size guide

    This vest is an outer layer, and has therefore been designed to fit slightly looser than our Foundation Jerseys in order to accommodate full pockets and layers being worn underneath.

    Sizing changes as of December 2020

    We're always striving to make our products the very best they can be. Part of that process is about listening to feedback from the people who buy and wear our clothing week-in, week-out. To see what changes we've made to our men's vest sizing, please click here.

    1. CHEST: Start by measuring your chest all the way around at the fullest part with your arms by your sides. Don't rely on your shirt or suit size. Then use this number to see which size options you fall into from our size chart below.
    2. BELLY: Next, measure your belly/waist all the way around at the fullest part. This'll usually be around your belly button. Don't rely on your jeans or trousers waist size. Then use this number to see where you fall on our size chart. If your chest and belly measurements put you in two different size brackets, we'd recommend opting for the larger size.
    3. ZIP LENGTH: Use the number in the zip length column to work out how each size will fit on you, and make sure you're happy with the length. Keep in mind that our Foundation Vest has a high collar, so the zip will start just below your chin.
    4. FIT: Do you fall into more than one size bracket? Then we'd recommend considering how you want your kit to fit. Do you like it close fitting? Or prefer it a little looser? Make sure your chosen size selection reflects how you like to wear it.

    STILL IN DOUBT? GET IN TOUCH: If you're still unsure, email us on and we'll be happy to assist you. We'll always start by asking if you've measured yourself and where your measurements put you on our size chart, so it's definitely worth doing this first. We may then be able to offer a bit of extra guidance on how it'll fit.

    While we do our best to accurately display the true colours of our garments in all photography on our website, sometimes the actual colour may vary in real life. This is because every computer/phone monitor has a different capability to display colours, and that everyone sees these colours differently.
