>>201980I do, however rain pants and a rain parka will never keep you as dry as you need to be if you need to shelter in place. I usually wear a full gore-tex setup if I'm actually doing SAR, but for dayhikes I just wear my normal hiking clothes (all synthetic or wool) and carry a bivy. At first sign of a viable threat in weather if I'm more than 3 miles from the trailhead or other shelter, I stop, shelter up, and wait. Better to be late getting home than to try hiking back out right as a storm hits and take truly un-needed risks.
Whereas if I'm working, unless the weather is truly insane, you have a safety net of a full team, communications, and all the other trappings, so you throw on your gore-tex and keep searching.
People kind of think I am too careful when it comes to being outdoors, but having done SAR and seen how easy it is for even experienced outdoorsmen to end up in the shit, I would rather take too many precautions.
But back on topic for OP, look at 1 man tents. I use an REI Passage 1, and have found it a great tent. I hiked all of the AT in MA and VT using this tent.
