Strengths: Works very well for rain rides, keeping the feet dry, and on colder days down to 45F it blocks the wind very well.
Weaknesses: Zipper is slightly irritating, keeping the overall review to a 4.
Bottom Line:
Great for mid-range (45F to 60F) temps and rainy rides, it IS waterproof and does a great job blocking the wind. If you ride colder, you'll want to combine it with toe covers.
