"What Our Gearhead® Experts Are Saying: ""I use this layer anytime I’m dealing with full sun and high output. It dries incredibly fast, never feels clammy, and the UPF protection is a huge plus on long days outside. The half zip makes it easy to dump heat, and it works just as well on the water as it does on the trail."" When the sun is relentless and the days are long, we reach for the Helly Hansen HH Lifa Active Solen 1/2-Zip Jacket. Designed for adventures with extended sun exposure, this lightweight layer keeps us comfortable whether we’re hiking exposed ridgelines, spending hours on the water, or pushing through warm spring ski days. Part of the Solen collection, this top blends two performance-driven technologies. S. Café® infuses the fabric with recycled coffee grounds to deliver UPF 50+ sun protection without chemical treatments, while also enhancing durability and quick-drying performance. Inside, LIFA® Active technology uses a hydrophobic polypropylene layer to move moisture away from the skin, keeping us dry and comfortable as output increases. With a breathable construction, half-zip ventilation, and clean, low-profile design, it’s a dependable layer for staying cool, protected, and focused under the sun."
