Layer Three: Cycling Jackets and Vests
An outer shield against the elements: gusty winds, rain, snow, and temperature drops. Learn when to reach for an ultralight vest in your pocket, when to reach for a 20,000 mm jacket, and when to reach for insulated winter armor.

Why is layer 3 crucial for your safety and health?
When you're riding at 30 km/h in a temperature of 10°C, the wind's momentum causes your body to feel only about 4°C (the so-called windchill factor). A wet chest exposed to such cold guarantees rapid hypothermia, a drop in performance, and a cold.
The purpose of the third layer is to keep wind and water out, while allowing water vapor produced by the body to escape through the pores of the membrane. In the INONI range, layer 3 is divided into three key categories:
1. Cycling Vests (Gilets)
Lightweight and packable into a small roll that fits into a pocket, they protect your chest from cooling down on descents and on cool mornings, while the mesh back prevents your back from overheating.
2. Windproof and rainproof jackets
Membrane models (Ittai, Event, Zero Wind) feature a DWR Aqua Repellent hydrophobic coating, while the flagship 307 2.0 model features 100% welded, thermo-adhesive seams for protection against downpours.
3. Deep winter jackets
A combination of a windproof armored membrane and SuperRoubaix internal insulation. Designed for riding below 5°C, in frost and snow.
The most advanced rain jacket in the INONI range. The three-layer Ittai Event membrane offers 20,000 mm of waterproofness and ≥20,000 g/m²/24h breathability. Version 2.0 features full tape-sealing, eliminating the only point where water could penetrate through the machine needle.
Thermo-welded seams: Guarantee 100% tightness even during long hours of heavy rain on the road or gravel.

A featherlight windbreaker with an Ittai membrane (10,000 mm / ≥8,000 g/m²/24h). It easily fits into a jersey pocket. The Aqua Repellent hydrophobic coating repels drizzle and tire spray. Essential for windy days in spring, summer descents, and early autumn.
Proven over the years, this construction features an Italian Zero Wind / Montreal membrane (17,000 mm / 17,000 g/m²/24h). It offers an excellent balance between thermal insulation and rain protection. Ideal for temperatures between 5 and 15°C as a top layer over a T-shirt or sweatshirt.
If you had to choose only one outerwear accessory for cycling, it would be the V85 vest. The front, made of dense, windproof material, protects the chest from the wind. The back, made of stretch mesh, wicks away excess heat generated by the back. When rolled up, it takes up half the size of a jersey pocket.
When to use: 10°C to 20°C. Put it on in the morning for a cool start, take it off when the sun comes out, and put it on again for a long, cold descent in the mountains.

Designed for cyclists training throughout the winter and after dark, the Zero Wind outer membrane blocks icy winds, while the inner microfleece retains body heat. Additional reflective panels ensure you're visible to drivers from over 200 meters away.

A clean, minimalist design with maximum thermal performance. The high, contoured collar protects the neck from drafts, while the extended back protects the lower back from the cold and water thrown up by the rear wheel. Perfect for pairing with Merino expedition base layers (layer 1).
A jacket is just the outer shell. The real magic of microclimate comes from working with base layers, a T-shirt, and a thermal top. Check out the rest of the guide and create an outfit for any weather.
