2-in-1 running shorts are the simplest choice for getting started. The built-in tights prevent chafing, while the loose-fitting shorts keep your legs free. The SpectraRun and TopoRun have three pockets and an adjustable double-cord belt. If you prefer lighter, form-fitting bottoms, the TerraRun Tight weighs 88 g.

The Performance Max Short 2 in 1 has an elasticated front pocket designed for a 250 ml flask or a bar. The Trailxplorer Short 2 in 1 goes further: its 360° carry belt has a wide mesh tunnel pocket all around the waist, for multiple flasks and nutrition. For more volume, add a hydration belt.

Yes for the ZipRun Short 3 in 1. Its zippered back pocket features a waterproof membrane that protects your phone and documents. The other models have a standard zippered pocket or a pocket in the cycling shorts: your phone stays in place, but it is not protected from water. In heavy rain, also slip it into a small bag.

The construction is the same: 75 GSM outer shorts, 180 GSM mesh liner, 3 pockets, jacquard waistband and double drawstring. Two things change. The sublimation-printed graphic matches that of the t-shirt from the same series. The concealed zip pocket is on the front left side of the SpectraRun and on the back of the TopoRun.

The Trailxplorer 2-in-1 Short is the only one in the collection with a pole carry system: an elastic band with silicone grip on the back holds the poles when you are not using them. Its cut is longer than that of the Performance Max and it weighs 225 g in size M.
