Developed for all-seasons-in-a-day type hikes, the Modis Triclimate Jacket provides lightweight warmth, wind and rain shelter and full-on weather protection. The inner layer uses HeatSeeker™ insulation to effectively retain body heat even in damp conditions. The outer layer is made from waterproof and windproof DryVent™, delivering reliable and durable protection against wind and rain. It's also highly breathable, so when worn independently you can keep on trekking through the elements without getting too hot. Wear both layers together when at rest, or the rain is pouring and the wind is blowing for full-on protection and insulation.
