The Robens Chinook Ursa S is a roomy shelter designed to give campers a solid basecamp on outdoor trips. Spanning 375 by 390 cm and standing 245 cm tall, it offers enough space for groups to relax, cook or store gear without feeling cramped.
Its outer tent is made from Robens’ HydroTex Polycotton, a 65/35 polyester–cotton blend that combines toughness with natural breathability to help reduce condensation inside. The groundsheet is 210T Oxford polyester with a 10 000 mm waterproof rating, so you’ll stay dry even during prolonged rain. It comes complete with pegs, guy lines and a carry bag for straightforward setup and transport.
HydroTex Polycotton blends polyester’s tear resistance with cotton’s ability to improve airflow, keeping the interior more comfortable. The 10 000 mm figure refers to the hydrostatic head of the groundsheet—essentially the height of a water column it can withstand before leaking—so it holds up well under sustained showers.
