A:Sure, Casey. There are lots of good tents out there that will work well for you. Probably a solid three-season is the ticket.
If you want a fair amount of ventilation (not a bad idea with four people), then a good choice might be Sierra Designs four-person Lightning XT 4 ($450). Its big advantage is weight. It comes in at just over seven pounds, which means you can spread it out nicely into loads of around two pounds (canopy/fly/poles and stakes). It includes a full-coverage fly for wet weather. But the canopy is mostly mesh, so not the warmest tent. Comfortable in humid weather, though.
For something a little more buttoned-down, take a look at the Marmot Halo 4P ($399). Another four-body rig, it has a canopy with good ventilation but also a generous amount of ripstop nylon, so it will keep drafts out fairly well. I like its vertical walls, which create a lot of head space and a real feeling of roominess. The sturdy design sheds wind and rain like a turtle, too. The extra protection does extract a price, however. The Halo 4P tips the scales at around 12 pounds. Not terrible when split up four ways, but still a heftier tent than the Lightning.
If a three-person tent is adequate, take a look at Black Diamonds Oasis 3 ($360). It offers a nice mix of light weight (just over six pounds), good weather protection, and adequate size. Not quite as beefy as the Marmot, but a solid tent.
Lastly, if you can afford it, just be done with it and get a Hilleberg Keron 4. Its a big tunnel-style four-person tent made in Sweden, where they know a little about crummy weather. The Keron is admirably light (nine pounds), super-tough, and extremely weather resistant. I especially like its twin vestibules and doors, so there are lots of options for getting in/out and stashing boots and other gear. OK, it costs $825. But youll love it.
