I prefer one long length rain jacket, rather than a short jacket and weather pants. As realistically it's more difficult to stop and get on pants and it's an extra item to carry and negotiate in your pack. Luckily I'd read a review that said this was cut a little on the small side, and I ordered one size larger. (I'm a standard medium and I ordered a large.) This was a good idea, as you will also likely have layers underneath, so even aside the slightly small fit to size - it's also that you want room to be able to wear a puffer jacket or anything underneath for insulation in cold weather. In the size up, it was perfect. It's ridiculously light, packs down small, very versatile - I love it.
