The Sierra T by JACK WOLFSKIN is a light, elastic functional shirt made of recycled material with active moisture management and freshness function.

Jogging, trail running or speedhiking - you love everything where you can really power yourself up. The Sierra T by JACK WOLFSKIN keeps you performing all the time.

The elastic shirt has a loose, sporty cut. It absorbs moisture particularly well from the skin, wicks it away to the outside and dries quickly again.

The other properties of the Hydropore-material also ensure that you enjoy your ambitious tours all around: It is super-elastic and gives odours no chance.

    • Function shirt: Moisture-regulating, lightweight, elastic, odour-resistant, main material 100% recycled, Uv-protection
    • Hydropore Ecosphere Q.M.C. S.Fresh Uv: lightweight: Elastic and 100% recycled knitted fabric with smooth surface, active moisture management, freshness function and Uv protection factor 40+
    • Quick Moisture Control: The Q.M.C. (Quick Moister Control) fibre technology provides active moisture management for fleece, functional shirts and underwear. This means that it absorbs excess sweat and quickly guides it away from the skin. The result: the material dries quickly and at the same time protects against cooling down!
    • Uv Shield: Jack Wolfskin only uses materials for its UV-protective clothing in which UV protection is not achieved by chemical finishing. Instead, it is created, for example, by the use of special yarns and/or by the special construction of the fabric (e.g. extremely dense weaving). This has many advantages: The function is anchored in the material itself - so the protection is permanent and cannot be removed by sweating or contact with water. The UV protection factor is also suitable for strong solar radiation (UVA + UVB protection).
    • S. Fresh: S.Fresh is ideal for longer, strenuous tours. It describes the treatment of garments with the active substances titanium and silver chloride, which inhibit the proliferation of odor-producing bacteria. The deodorant for your clothes, so to speak!
    • Hydropore: Hydropore is the epitome of versatility. As a double-knit material, it has good insulating properties, is also abrasion-resistant, breathable and elastic enough to withstand any movement. Together with its odour inhibiting properties and UV protection, it is the ideal material for long, intensive trekking tours or other endurance sports.
