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.

“Made from a lightweight, stretchy mesh that draws excess moisture away from the skin and aids heat regulation, this lightweight base layer is perfect for mild and warm weather riding. It's been tailored to be close fitting, with minimal seams, so that it feels both comfortable and discreet under your jersey. The length on this base layer has also been specifically cut to sit at the same height as our jerseys, in order to avoid visible bunching that can often happen when your base layer is tucked into bib shorts.”

Emily Childs, Managing Director and Product Developer at Attacus

Size Guide

Attacus size guide

The technical fabrics in our base layer are designed for movement, and will naturally stretch. It's why you may find you fit into more than one size bracket. So to help you find the best fit for you, we recommend you follow the steps below.

  1. Start by measuring your chest all the way around at the fullest part. Then use this number to see which size options you fall into from our size charts below.
  2. Use the number in the torso column to work out how each size will fit on you, and make sure you're happy with the length.
  1. Consider how you want your kit to fit. Do you like it quite close fitting? Or prefer it a little looser? Make sure your chosen size reflects how you like to wear it.

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.

Care Instructions

Open tab

All of our garments are made with high quality technical fabrics which, with a bit of TLC, have been designed to last you many seasons of riding.



Machine wash on a low spin with similar colours at no higher than 30°C (86°F). Use non-biological detergent only and avoid fabric softeners and bleach.

Close all clasps and fastenings on your cycle kit – and any other garments mixed in with your kit – when washing. Velcro closures and clasps can catch on stitching and damage your garments.


Do not tumble dry. Hang up and leave to dry naturally away from direct sunlight to prevent wear.


Wipe clean with a warm damp cloth. Do not machine wash or tumble dry.
