There's not much sense in carrying a rain coat without rain pants to go with it. You know that feeling when the rain is running off your jacket and straight onto your pants and whatever is in your pockets? Yeah, we don't like it either. So pick up a pair of ultralight Rab Tempo pants, the perfect companions to any ultralight rain jacket. At just nine ounces, they're a great just-in-case rain pant for day hikers or a go-to pant for lightweight enthusiasts.
