Castelli Transition Air Vest
The Castelli Transition Air Vest is a lightweight, windproof cycling gilet designed to provide an extra layer of protection when temperatures drop or conditions become breezy. Ideal for road cycling in changeable weather, it combines windproof fabric with a tailored fit that sits neatly over a cycling jersey without unnecessary bulk. Whether you’re setting off on a cool morning, tackling an exposed climb or preparing for a long descent, the Transition Air Vest provides convenient wind protection without the need for a full cycling jacket.
Designed for versatility, the Castelli Transition Air Vest features a two-way zip for flexible ventilation, an elasticated waistband to help maintain a secure fit and reflective Castelli detailing for improved visibility in lower-light conditions. Its lightweight construction makes it easy to layer over your usual cycling clothing, while the streamlined design is suited to riders who prefer a close-fitting silhouette. With a recommended temperature range of 12C to 20C, it’s a practical choice for spring, autumn and cooler summer rides.

Windproof Protection for Changeable Conditions
The Castelli Transition Air Vest is designed to reduce the cooling effect of wind when riding in exposed conditions. Its windproof construction provides an additional barrier over your cycling jersey, making it particularly useful for early starts, cooler descents and rides where the temperature changes throughout the day. With a windproofness rating of 5/5, the vest prioritises protection from moving air while retaining a lightweight design.
Lightweight Construction for Easy Layering
Made from 100% polyamide, the Transition Air Vest offers a lightweight additional layer without the bulk of a full cycling jacket. Its 5/5 lightness rating makes it a practical option when you need extra protection but want to avoid unnecessary weight. The vest can be worn over a short-sleeved or long-sleeved cycling jersey, depending on the conditions and your preferred layering system.
Tailored Fit for Road Cycling
The Castelli Transition Air Vest features a tailored fit designed to create a clean, streamlined profile on the bike. Its elasticated waistband helps keep the garment securely positioned while riding, reducing unwanted movement as you change position. This makes it suitable for road cyclists looking for an additional layer that complements close-fitting cycling clothing.
Two-Way Zip for Flexible Ventilation
A two-way front zip allows the vest to be opened from either direction, giving you greater flexibility when adjusting ventilation. This is particularly useful when your effort changes during a ride, allowing you to release excess heat on climbs while keeping the upper section fastened if preferred. The zip also makes the vest easy to adjust when stopping for a break.
Reflective Castelli Details
Reflective Castelli scorpion and wordmark details help improve visibility to other road users when illuminated in lower-light conditions. These subtle reflective elements add a practical feature for early morning rides, overcast days and journeys home as daylight fades.
Recommended Temperature Range: 12C to 20C
Castelli recommends the Transition Air Vest for temperatures between 12C and 20C. This makes it a useful option for transitional weather, when a cycling jersey alone may not provide enough protection against wind but a full jacket could feel excessive. The ideal combination of layers will depend on your riding intensity, the weather and your personal preference.
Who Is the Castelli Transition Air Vest For?
The Castelli Transition Air Vest is ideal for road cyclists looking for lightweight wind protection without compromising their riding position or adding unnecessary bulk. Its tailored fit, two-way zip and elasticated waistband make it particularly suitable for training rides, weekend road cycling and longer routes where temperatures and wind conditions can vary. For riders who regularly head out in spring, autumn or cooler summer weather, the Transition Air Vest provides a versatile addition to their cycling wardrobe.
