Marmot designed its Women's Frequency Hybrid Jacket for active endeavors in the mountains. Wear it by itself when you're trail running in the shoulder seasons, and pair it with a hardshell for winter skiing. Its Polartec Power Dry High Efficiency lining moves moisture away from the skin to dry quickly, so you won't feel sweaty. The mini ripstop shell brings the durable wind protection without the weight, and stretch knit side panels ensure a full range of motion. Marmot also added thumbholes to keep your sleeves from riding up, a drop tail hem for enhanced coverage, and reflectivity for visibility in low light.
