How to choose the best waterproof cycling jacket

Main features of a waterproof jacket

Before choosing a cycling rain jacket you will have to carefully evaluate different aspects, comparing the various models and the technologies and materials with which they are made. Here are the essential features a good waterproof jacket should have:

• high waterproofness: this is the key feature of a rain jacket and is typically measured in millimeters of water column. This value indicates the pressure the fabric can withstand before the water begins to penetrate: for example, a fabric with 10,000mm of water column can withstand the equivalent pressure of a 10-meter-high water column. The best-performing jackets - such as those proposed by Nalini - are made with DWR (Durable Water Repellent) materials or treatments, or with technical membranes that completely block water droplets, keeping the body perfectly dry even in case of heavy rain. 
• Optimal breathability for sweat management: a waterproof jacket should be just as effective at expelling internal moisture as it is at blocking external moisture. The best technical fabrics integrate microporated membranes or advanced coatings that allow (smaller) vapor molecules to escape while preventing (larger) water droplets from entering. Some models may feature ventilated panels strategically placed under the armpits or on the back to further increase air circulation.
• Ergonomic design: the design of a waterproof cycling jacket is different from that of a casual jacket. The tissue must be longer on the back than the front to effectively protect the lumbar area when assuming a bent, aerodynamic position. Instead, the front must be shorter to avoid annoying creases and ensure maximum freedom of movement while pedaling.
• Heat-sealed seams: seams are the weak points of any waterproof garment. In quality cycling rain jackets, all seams are heat-sealed through the application of waterproof tapes that completely seal the holes created by the needle during sewing. A good waterproof jacket should feature heat-sealed seams on all critical points, including sleeve joints, hips, shoulders, and pocket areas.
• Low weight and compact construction: the ability to easily store the jacket when not needed is essential for road or gravel cyclists. A quality rain jacket should therefore feel lightweight while maintaining high performance. The best jackets are those that can be folded and easily stored in a back pocket of the shirt or in a small saddle bag.
• Reflective inserts for visibility and safety: Riding in the rain often means facing poor visibility conditions, with overcast skies, fog, or even darkness on morning or evening winter rides. Cycling jackets should therefore incorporate reflective inserts strategically placed on the shoulders, back, arms or chest. The most safety-conscious models can also have high-visibility colors or entire sections of reflective fabric that works even in the absence of direct light.
• Functional and accessible pockets: the pockets of a cycling jacket must be designed to be accessible even on the go and to protect the contents from water. Many models feature at least one waterproof zip back pocket, large enough to hold smartphones, keys, or energy bars. Some jackets also feature side or chest pockets, always with protected zips. It is important that pocket zips are easily accessible and openable even with one hand.

How to choose the jacket based on the type of cycling practiced

Road cycling and gravel, while sharing many similarities in clothing, have some specificities that can influence the choice of the ideal rain jacket. In road cycling, where the position is more aerodynamic and the speeds higher, racing-cut jackets are preferred, with a tighter but non-constrictive fit, which do not create resistance while pedaling. 

The ideal jacket models for cyclists training on the road are the ultralight and compressible ones, which can be easily stored in a back pocket of the shirt when not needed. When traveling long distances, it's quite common to go from dry to rainy conditions and vice versa during the same outing, so a jacket that takes up little space can become a valuable ally. 

For those who practice gravel, however, the approach may be slightly different. Dirt road adventures expose the cyclist more to mud and splashes, so a jacket with a sturdier protection at the bottom can make all the difference. Additionally, since gravel often involves riding in remote areas and on off-road trails, some cyclists may opt for slightly heavier jackets, sacrificing practicality for greater protection. 

Cyclotourists and cyclists who mainly travel on urban routes have even different needs. Those who use their bike for daily commutes, for example, might appreciate jackets with additional pockets for storage and a less racing, more casual style that allows you to wear the jacket even once you get off the bike. Furthermore, in these cases, the possibility of folding the jacket is less of a priority than resistance and ease of use.

From a practical point of view, the Breva Wind jacket is equipped with a YKK® reverse zip with cam lock pull, zip garage and internal wind barrier, elements that prevent the entry of cold air and ensure optimal thermal insulation. Comfort is further enhanced by the soft fabric-lined neck and silicone gripper elastic bottom that keeps the jacket perfectly in place while pedaling. There is no shortage of three back pockets, essential for those facing long distances, nor the reflective logos to increase safety in low light conditions. The jacket also integrates the new ICE KEY DEVICE, an innovative system designed for cyclist safety. Despite its three-layer construction, the Breva Wind Jacket remains incredibly lightweight and easily foldable, perfect for carrying around at all times.

The Scirocco Wind Jacket, on the other hand, is a lightweight and highly versatile windproof jacket, designed to deal with variable weather conditions and to ensure protection without sacrificing maximum breathability. Windstopper fabric with microdesign ensures an effective barrier against the wind, reducing the dispersion of body heat and keeping the cyclist warm on descents or cool days. 

The presence of elasticized fabric side and under-sleeve panels improves the fit and promotes moisture management, offering a feeling of constant comfort. The Scirocco jacket is particularly appreciated for its packability: it can be folded and easily stored in a shirt pocket or backpack, becoming an essential item for those who don't want to be caught unprepared by changes in temperature or wind. Featuring a front zip with extended pull and internal windproof fin, it offers an excellent balance between protection and ventilation. The elastic bottom ensures stability in the saddle, while the refractive logos increase safety on evening outings or with poor visibility. 

The Storm Jacket represents the pinnacle of Nalini's rain protection, a jacket designed to tackle the most extreme conditions by combining comfort and performance. Made of completely waterproof materials and heat-sealed seams, it guarantees total protection against rain, while maintaining good breathability thanks to the presence of advanced technical membranes. The ergonomic design, combined with stretch fabrics at strategic points, ensures a snug yet comfortable fit, suitable for more intense outings. 

The Storm jacket integrates technical solutions such as waterproof zips, tight-fitting cuffs to prevent water infiltration, a protective raised neck, and strategically placed refractive details to improve visibility in extreme conditions. Extremely lightweight and easily foldable despite the high level of protection, it is the perfect choice for cyclists who tackle long rides or who want a reliable garment for winter and days of heavy rain. Versatile, durable and designed to last, the Storm Jacket completes the Nalini offering for cyclists seeking the greatest possible protection.

Fit and sizes: how to find the perfect jacket for you

A cycling rain jacket, however technologically advanced, will not be able to express its potential if it does not fit properly. Wereability is crucial: a jacket that is too loose can create air pockets and cause annoying creases and chafing, while one that is too tight can limit movement and compromise breathability by creating sweat storage points.

Technical cycling jackets are generally characterized by a fit called "slim" or "performance," meaning snug but not constrictive, designed to perfectly follow the lines of the body when assuming the saddle position. This is different from the "regular" or "comfort" fit of some jackets more oriented towards urban cycling or leisure. When choosing a size, it's important to consider that other layers will be worn under the rain jacket: in mid-seasons, perhaps just a long-sleeved cycling jersey, while in winter, a thermal underwear jersey can also be added.

Nalini offers a detailed size guide to help you choose, based on chest, waist, hip, and leg measurements. If possible, try on the jacket by simulating the position in the saddle: leaning forward as when holding your hands on the low crease of the handlebars will allow you to verify that the back is long enough and that the sleeves do not retract, exposing the wrists. Arm movements should be free, with no tension on the side panels or shoulders.

The art of layering also requires the ability to modulate: in a long exit where conditions can change, having the ability to remove or add a layer makes all the difference. A squeezable rain jacket can be stowed away when it stops raining, while an ultralight wind vest - such as the Scirocco Wind vest - can be easily added or removed as the temperature or intensity of the effort varies.
