Description

The Tern Ultralight Merino Wool Hoodie is built to give you the comfort of natural fibers with the performance of modern technical fabrics. Using an ultralight merino blend and advanced NuYarn™ construction, it delivers breathability, odor resistance, and temperature regulation in a layer that works across a wide range of conditions. Whether you're hiking in cool mornings, exposed sun, or changing weather, the Tern adapts without needing constant layer changes.

Designed as a versatile base layer or standalone hoodie, it keeps you comfortable longer by managing moisture, resisting odor, and maintaining its shape over time. It won’t dry quite as fast as a synthetic, but it offers a more balanced performance for multi-day trips, travel, and extended outdoor use—making it one of the most adaptable layers you can carry.

How The Tern Keeps You Comfortable

Stronger Than Traditional Merino

Built For Multi-Day Wear

How The Tern Keeps You Comfortable

The Tern is designed to regulate temperature rather than trap heat. The ultralight 115 GSM merino blend allows airflow while reducing direct sun exposure, helping your body stay more stable in changing conditions.

Compared to synthetic sun hoodies, it may feel slightly warmer in extreme heat, but it excels in variable conditions where mornings are cool, afternoons are warm, and you need one layer that adapts.

Stronger Than Traditional Merino

The Tern uses NuYarn™ technology, which wraps merino fibers around a synthetic core to improve durability, stretch, and shape retention. This makes it significantly stronger than traditional merino wool while maintaining the natural comfort and performance of wool.

It’s built for real use in backpacking and outdoor conditions — not just casual wear.

Built For Multi-Day Wear

Merino wool naturally resists odor-causing bacteria, allowing you to wear the Tern for multiple days without washing. Combined with improved durability from its blended construction, it’s designed for extended trips where washing isn’t an option.

This makes it a reliable choice for backpacking, travel, and long outdoor use.
