All-weather protection meets freedom of movement

Lightweight, windproof, waterproof & breathable dog jacket

Many lightweight dog jackets are designed only as raincoats — SportWarmer is much more than that. Its advanced technical fabric features a windproof membrane that prevents cold air from penetrating, helping your dog stay warm even in cool, damp conditions. At the same time, the jacket offers excellent breathability, allowing moisture and heat to escape from the inside. This keeps your dog comfortably dry and prevents overheating during activity.

Whether you’re training, walking, or adventuring together, the SportWarmer keeps your dog warm, dry and comfortable without restricting movement. This jacket offers:

• Reliable protection from wind, rain and chill — perfect for cool weather walks (+10 to −5°C), and even colder conditions for dogs with thick coats or high activity levels.
• Breathable and stretchy comfort — the innovative multilayer Tekseries® technical fabric moves with your dog, comfortably accommodating every twist, turn and sprint.
• Membrane technology that blocks cold air while allowing heat and moisture to escape, keeping your dog dry inside.

Every detail is designed around how dogs actually move and perform – warm where it matters, flexible where it counts, and exceptionally comfortable for all-day wear.

Comfortable fit & free movement – Dogs love wearing it

The fabric is exceptionally soft, elastic and quiet, ensuring maximum comfort for your dog. Unlike many shell jackets, SportWarmer does not feel stiff or noisy, making it suitable even for dogs that are usually reluctant to wear jackets.

Many dogs happily wear SportWarmer for long periods thanks to its lightweight and barely-there feel. Thanks to its great cut, light fabric and excellent stretch, your dog will hardly notice that it’s wearing a jacket.

The jacket’s design is also perfect for sports: tailored to fit dogs of all shapes and sizes, covering all the big muscles and staying in place even at full speed, while still allowing complete freedom of movement. The soft materials are nice and stretchy, so your dog can move freely. The high multipurpose collar can be worn up to provide protection from rain and wind, folded down to the length of your choice or worn as a hood to keep your dog’s ears covered.

• Ergonomic fit designed for dogs of all shapes and sizes.
• Tailored cut that covers major muscle groups while allowing full freedom of movement.
• Versatile high collar — it can be worn up, down or as a hood to protect the dog’s ears and head.
• Reflective edging for excellent visibility from all directions.
• Curved tail opening ensures a comfortable fit for dogs with all tail types, including upright ones.

When is the SportWarmer the right choice?

SportWarmer is ideal when you want a lightweight dog jacket that protects against wind and rain but is cold-resistant and breathable.

For very cold winter temperatures (below -10°C), we recommend switching to a warmer insulated jacket version, the ProWarmer winter jacket.

Product & care instructions

• Machine wash (delicate wash at 30°C), but do not use fabric softener or tumble dry.

What size will fit my dog?

Only when the jacket is the right size for your dog it shows all the best qualities and works as designed.

Choosing the right size – important notes

How to measure your dog, back length (measurement A)

To ensure the best possible fit, please pay special attention to the following measurements:

• Measurement A (back length) is the most important measurement. Measure from the withers to the base of the tail.
• Measurement C (chest circumference) is also important. For this jacket, it is measured approximately 5 cm behind the dog’s front legs. The size chart shows the length of the adjustable waist strap.
• Measurement B (neck circumference) is especially important for dogs with a heavier build or a thick coat, to ensure the neck opening is sufficiently roomy.

When trying the jacket on your dog, it is important to put the leg bands on to ensure that the rear section stays firmly in place and does not push forward when the dog moves.  The fabric stretches about 14% to allow complete freedom of movement.

At the bottom of this page, you’ll find a separate size chart with example breeds and tested sizes. Please note that this chart is intended as a guideline only. Always compare your dog’s own measurements with the size chart — and remember that back length (Measurement A) is the most critical measurement.

Please note that these are approximate example measurements for dogs. If your dog, for example, has short legs or an especially long back, these measurements may not match your dog exactly. There is also great variation within different breeds. The most important measurement is always your dog’s back length.
