What Our Gearhead(R) Experts Are Saying: "The Stream Cap is perfect for high-output trail runs. It's super light, breathes well, and the fit is super comfortable thanks to the elastic back. The ponytail opening is a nice touch for longer hair days-and it packs flat in my vest when I don't need it." When we're chasing vert and dodging sun on the trail, the La Sportiva Stream Cap keeps our focus dialed. Designed for mountain running, this ultra-lightweight cap features breathable mesh construction that keeps airflow high and sweat low, even on exposed ridgelines and steep climbs. An elastic back band offers a secure, comfortable fit that stays in place through every stride, and the integrated ponytail hole helps manage longer hair without compromising coverage. Whether we're racing peaks or logging training miles, the Stream Cap delivers cool-headed performance with a minimalist feel.
