In 1997, EXPED introduced an entirely new tent design to the world - the ridge-tunnel. It combines the generous space and low weight of tunnel tents with the stability and free-standing properties of geodesic tents.
The Carina II and IV tents are excellent examples of this pole structure's advantages. Because the ridge pole is placed at a 90 degree angle to the tunnel poles, it acts like a spreader bar and makes the canopy of the tent completely free standing. Continuous pole sleeves provide even tension along the entire length of each pole, creating a very taught structure. The Carina tents borrow this architecture from a long-running EXPED design, the Venus II/III. Those are 4-season tents that utililze exoskeleton (poles in fly), making them outstanding shelters in rough weather. In the Carina, the endoskeleton (poles in canopy) emphasizes ventilation and warm weather versatility, as well as star gazing! In the photos shown here, from sea kayaking trips in Baja, Mexico, the Carina II is set up without the use of stakes - very convenient!
But, of course, it's not all sun and calm weather out there in the wild world, so Carina has a very nice fly for when the rain and wind roll in. The two doors match up with two roomy vestibules for gear and dry coming-and-going. And notice the roll-up feature of the fly. If it's a nice evening when you go to bed, start out with both ends of the fly rolled up for star gazing. If it starts to rain in the night, simply unroll the fly, clip it into place at the pole ends and sleep tight. The roll-up fly also allows just one side of the fly to be deployed, creating a privacy screen on one side and expansive views on the other.
