For those of you planning summer training retreats or off-grid survival camps, don't overlook your shelter. I’ve found that a wall tent is the only way to go if you're staying for more than a couple of days. I’m currently using the 17.2 model from Coody, which offers a massive 185 square feet. It’s an inflatable "house" style that doesn't have a center pole, so you have a completely open floor plan for gear, weights, or cots. It’s built to stay for seasons, and the air-beam frame is incredibly rigid. If you want a basecamp that feels like a fortress rather than a flimsy bag, this is the top tier of gear for serious mountain training.
