Functional Jackets - Spring & Summer

What is a transitional jacket?

A transitional jacket is designed for the period between seasons, when the weather changes quickly and temperatures typically range around 5–15 degrees. It must be able to handle cool wind in the morning, light rain during the day and milder temperatures later in the afternoon. Unlike heavy winter outerwear, the construction is lighter and more flexible, but with a greater focus on weather protection than a very light summer jacket.

Transitional jackets for women are therefore often designed with technical materials that protect against wind and moisture without making the jacket stiff or warm like a winter model. Some variants are completely unlined and function as a protective outer layer, while others have light insulation that provides extra comfort on cool days. What they have in common is that they are made to perform in unsettled weather and for everyday use, where freedom of movement and temperature regulation are crucial.

What distinguishes a transitional jacket from a classic spring jacket?

A transitional jacket primarily focuses on protection against wind and rain, while a classic spring jacket often strikes more of a balance between style, light warmth and the season's silhouettes. While the spring jacket may be lighter and more style-oriented, the transitional jacket is typically constructed with technical details that make it more robust in wet and windy weather.

If you are primarily looking for a light jacket for mild spring weather and layering in dry conditions, it may be relevant to view the full collection of classic spring jackets in lighter materials.

If, on the other hand, you need a model that can better withstand rain and changing conditions, the transitional jacket is the more functional choice. It is designed to be worn both in early spring and in autumn, when the weather is rarely stable.

Waterproofness and breathability – what do the numbers mean?

When it comes to transitional jackets, technical measurements play a significant role. A water column pressure of 5.000 mm indicates how much water the material can withstand before it penetrates. In practice, this means that the jacket can handle ordinary rain and showers without becoming soaked through.

Breathability is often measured in grams per square metre per 24 hours, for example 5.000 g/m²/24h. This figure indicates how effectively the material can transport moisture away from the body. A transitional jacket with this balance between waterproofness and breathability is well suited to commuting, cycling and days with varying activity levels.

The construction also matters. Taped seams prevent water from penetrating through the stitching, while a TPU lamination on the back of the fabric can increase both wind and water resistance. Overall, these elements are what make a transitional jacket more technical than a traditional light jacket.

Long transitional jacket or short model?

The choice between a long and a short transitional jacket largely depends on the need for coverage and movement. A long transitional jacket for women provides extra protection over the hips and thighs, which can be an advantage in rain and wind – especially if you walk a lot or wait outdoors for transport. The extra length can also create a more cohesive silhouette and feel warmer on cool days.

A shorter model, on the other hand, provides greater freedom of movement and may be more practical for an active everyday life. It takes up less space, is easier to combine with layers underneath and may feel more flexible when temperatures fluctuate throughout the day.

The right choice therefore depends not only on style, but on how and how often the jacket will be worn during the transitional seasons.

When should you choose insulation in a transitional jacket?

Not all transitional jackets need insulation, but during periods with low morning temperatures or cool wind, a light insulating layer can make a noticeable difference. If you often head out early in the day or spend extended periods outdoors, a model with light padding can provide extra comfort without feeling like winter outerwear.

Light insulation works particularly well at temperatures close to 5–10 degrees, where a completely unlined jacket may feel too cool. It is all about balance. Enough warmth to keep out the cold, while still focusing on breathability and freedom of movement. For the coldest transitional days, it may also be relevant to take a closer look at lightly insulated down jackets for cool transitional days.

These models combine low weight with effective warmth and can be an alternative if you prioritise insulation more highly than full waterproofness.

Transition from spring to summer

When temperatures begin to rise steadily, needs change. A transitional jacket that was previously perfect at 8–12 degrees can quickly feel too warm when the sun grows stronger. At this stage, lighter materials and thinner constructions become more relevant.

The transition from spring to summer therefore often involves moving from technical protection to more minimalist solutions. If you primarily need a light layer for cool evenings or windy days, you can take a closer look at light summer jackets for milder temperatures. Here, the focus is typically less on water column pressure and more on comfort, flexibility and lightness.

Fit and freedom of movement

A transitional jacket must be suitable for movement. That is why fit plays a central role. If the jacket fits too closely, it can restrict layers underneath and reduce comfort, especially when temperatures fluctuate. Conversely, a model that is too roomy may feel heavy or less structured.

For commuting and cycling, it is important that the shoulders and sleeves allow room for movement, and that the length suits your daily use. Some prefer a more fitted silhouette, while others prioritise extra room for knitwear or light insulation underneath.

Trends in transitional jackets

Although transitional jackets are functional, they still follow the season's lines and colours. Many models combine technical materials with clean cuts, subtle details and colours that are easy to incorporate into the wardrobe. Classic shades such as navy, sand and olive recur, while seasonal colours can create a fresher look.

The cuts often range between minimalist and more sporty styles, with practical elements such as a hood, adjustable cuffs and concealed pockets forming a natural part of the design.
