Norrona Falketind Thermo 40 Shorts - Men's

Our most versatile and flexible insulation shorts.

Providing windproofness and water-resistance, the main fabric is a lightweight recycled 20D nylon. It’s also highly packable, and durable for its weight, making it perfect for bring-along insulation shorts. The main insulation is a recycled thermo40 with a thermo60 in the seat. The thermo40 insulation provides great insulation even when it is damp, has a high warmth-to-weight ratio, and is the most packable insulation product in our range. 

The shorts are the sibling to our falketind thermo60 Hood, providing the perfect balance between insulation, lightweight, and packability for your lower body. It’s an all-season, windproof insulation garment that works great as an outer layer or underneath a shell pant. With a full zip solution, these pants can easily be put on and taken off without removing your shoes/pants, and the zippers on the side are coordinated so you will not use valuable time trying to match them up. It compresses into a packable pocket on the thigh, which makes it super easy to bring along. 

The shorts have a technical fit yet fit over pants or shorts. It has an above-knee cap length and a quilted front around the hip flexors to lock the insulation in place in this area and achieve natural folds.
