This Spyder Eiger top is the ultimate mid-layer for cold weather adventures. It's crafted from a premium blend of merino wool and Sorona polyester, which gives you the best of both worlds: the incredible softness, natural warmth, and odor resistance of merino, combined with the durability, moisture-wicking, and quick-dry performance of a synthetic. The full front zipper makes it super easy to put on over a base layer or to vent quickly if you start to heat up during activity. The t-neck (or mock neck) design provides extra warmth around your neck without the bulk of a full turtleneck. It's designed as a technical layer, so it's breathable and moves with you, making it perfect for skiing, snowboarding, hiking, or any winter outdoor sport. But it's also stylish and soft enough to wear as a casual sweater around town. Spyder's quality is top-notch, so this is a piece that will last for seasons. If you need a versatile, high-performance layer that keeps you warm and dry without the itch, this is a fantastic choice.
