The Katabatic Tarn is a well-regarded, premium ultralight down jacket highly rated for its warmth-to-weight ratio, high-quality materials, and packability. It is best suited for 3-season, high-output outdoor activities, but users should be aware that it features a very slim, trim fit and small pockets. It is considered a legitimate and high-quality product from an established Colorado-based outdoor gear company.
