I agree with the previous comments about this tent.
Light enough for one to carry, it will be luxurious; do-able for two, it will then be ultralight. Four season version of the already good performing Hogan Ultralight 1 (read the article), the Argon is even more waterproof, versatile and simply top of the game.
