The Basecamp provides excellent insulation even in damp conditions. It is filled with 650+ fill power duck down treated with Ultra-Dry technology. The EN comfort rating of -4°C ensures cosy nights in chilly weather, while the innovative Free Flow Zip System allows for multiple configurations to suit varying temperatures and personal preferences.
Key features include an oversized hood accommodating a full-sized pillow, a relaxed fit for unrestricted movement, and an eco-friendly recycled polyester shell. The bag's versatility shines through its ability to convert into a blanket by removing the hood.
