Durable high-mileage shorts with fixed inner tight and stable storage
TEMPO! ONE Run Shorts are the solution for those who want the storage options of tights but the freedom of shorts. We have combined an ultralight outer short and a supportive, functional inner tight in one product that works equally well for marathons and high-volume training.
The challenge with many 2-in-1 shorts is often that the inner tight is too short or loose. This results in "riding up" during the run, or the shorts starting to sag as soon as you put a phone in the pocket. We solved this by reconstructing the inner tight from scratch.
We have extended the inner short to "True Tights" length. This means it reaches far enough down to grip under the large thigh muscle. This positioning ensures that the tight is fixed on the leg and does not move, no matter how fast or far you run. The material is fine-knitted and powerful, providing a firm, supportive feel – exactly as you know it from our long tights.
The firm structure of the inner tight is crucial for the pockets. Because the fabric is strong and sits close to the thigh, you can carry your phone or gels in the side pockets without them bouncing. Combined with the adjustable drawstring in the waist, this ensures the shorts stay exactly where they should, even when fully loaded. The outer layer is an ultralight shell that provides the airy feel and look many prefer on a run.
Details and materials
-True Tights length (fixed under the thigh muscle)
-4-way stretch
-Quick-drying and moisture-wicking inner tights
-2 x thigh pockets on inner tights (for phone/energy)
-Sewn-on FUSION flag logo
-Elastic waistband with adjustable drawstring (Essential when pockets are full)
-Powerlock lock seams (increased durability)

Technical, lightweight and ventilated run singlet
Lightweight comfort for training in warm weather
This sleeveless running top is technical, lightweight, and highly ventilated, built for both everyday training and competitive racing. Its performance fabric actively pulls sweat from your skin and dries rapidly, meaning the singlet won’t get weighed down or stick to you during hard efforts. Even in the summer heat, it helps keep you cool and dry.
The cut is a race-oriented athlete fit, which in this case is a medium-to-tight fit that sits close to the body without restricting breathing. By hugging your torso, it prevents excess drag from flapping fabric, yet it’s stretchy enough for complete freedom of movement. Whether you’re doing intervals on the track or lining up at a marathon, this singlet’s minimalistic design lets you focus on performance. It’s recommended for use in warm conditions (15°C to 30°C), perfect for summer runs.

Lightweight, breathable performance fabric
Quick-drying material that efficiently wicks sweat away from the skin

Your Daily Running Sock – Upgraded
TEMPO! TWO Run Sock is made for runs where comfort has to last all the way home. It adds extra cushioning under the foot and reinforcements in the areas that typically wear first.
On longer runs it’s rarely the legs that surprise you — it’s the feet. TEMPO! TWO is a classic running sock with a little more underfoot comfort and extra durability where running socks usually fail first.
We’ve added extra material under the foot for a more comfortable contact with the shoe and to take the edge off the load on longer distances. The toe and heel are reinforced for improved longevity. The fit is tuned to sit close and smooth on the foot, helping prevent bunching and friction.
The leg is mid height and slightly higher than our previous Run Sock, giving a bit more coverage around the ankle.
Made in Portugal as part of our European value chain.
-Versatile running sock for training and racing
-Reinforced wear zones at heel and toe
-Slightly higher leg for improved coverage and protection

Merino Wool
We exclusively use a mulesing-free top-quality wool from the German company Südwolle, which guarantees world-class handling of Merino wool for the European market.

The wool is easy to keep and is machine washable on a wool / delicates setting at 30 degrees. Do not tumble dry. To achieve the best results, the garment should be dried in a flat position to maintain its original shape.
Heat Regulation
Wool functions as a natural regulator that keeps you warm in cold conditions and cool in warm conditions. Merino wool transports moisture effectively which keeps the skin comfortable and dry.
