At 6-person scale, outdoor durability matters more than ever. Hardwearing Douglas Fir exterior cladding provides natural weather resistance — resisting moisture, UV damage, and temperature variation without compromising on appearance.
The extended roof overhang gives the C2 a commanding presence while providing practical protection from rain and the elements — shielding the structure and improving energy efficiency even in colder outdoor conditions.
Maximum Outdoor Presence

Built to Handle the Elements
