Have used the half sleeve in 15-30 minute summer showers and it kept me dry. takes up so little room, it is easy to just leave in your bag. also nice to take on hikes as it takes it little room in a daypack or fanny pack.
Not sure how it would hold up in a all day rain.
Material is lightweight and seam tape is fragile appearing--not sure how well this would hold up for frequent use, but it quite good to have for the occasional shower.
