Berghaus
Berghaus Paclite 2.0 GTX
Waterproof jacket with a Gore-Tex Paclite membrane (around 330 g). Fully waterproof with taped seams, fixed adjustable hood, storm flap behind the zip and cuff adjustment. Packs down small in a vest. Heavier than a pure running hardshell, but it meets the waterproof-breathable membrane requirement in race rules and is the affordable route into Gore-Tex.
Brooks
Brooks Cascadia 20 GTX
The Cascadia 20 with a GORE-TEX membrane: stability and protection for rocky mountain terrain, keeping the foot dry on cold, rainy days.
Gore Wear
Gore Wear C5 GORE-TEX Glove
Glove with a fully waterproof, windproof GORE-TEX membrane and light insulation. The pick for running in snow, sleet or heavy rain while keeping your hand dry.
Gore Wear
Gore Wear M GORE-TEX Thermo Glove
Warmer variant of the Gore Wear C5 GORE-TEX: the same fully waterproof, windproof membrane, with extra thermal lining for intense cold on top of snow or rain. The pick when the problem isn't just water, but water AND hard cold at once.

Chaqueta cortavientos impermeable ultraligera (135 g). Costuras selladas, capucha ajustable y ventilación trasera. Se pliega en su propio bolsillo.
Salomon
Salomon Speedcross 6 GTX
The Speedcross 6 with a GORE-TEX membrane: the same aggressive 5 mm lugs for mud and soft ground, now waterproof for winter, rain and snow.
