Solid accessory. Lightweight construction with a good waterproof membrane on the material. Packs up pretty small in its own pocket. Reflective logo on the front so people know who you carry. My only gripes which are smallish ones and sort of depend on the user. If you plan on carrying a tent or pad on the outside of your pack, you'll want a larger sized cover to go over those extra pieces of gear. If you're using the cover on a pack at the maximum size, it will be difficult to strap anything else on the outside of your pack. But that allows you to learn to pack more efficiently. The material is of great quality but it does tend to snag on branches and rocks. A couple holes here and there after 6 uses is no big deal. I just slap a little Tenacious Tape on there and call it good. Lastly, the rain cover does not cover the area between the pack and the user. That frame area is exposed and I have found water to find its way into the main compartment through this spot. No Rain cover is entirely waterproof but if you're worried, I would suggest a pack liner of sorts for extra protection. Overall, I really liek the color and reflective tones and the lightweight pack protection for most wet weather. I would defintely buy another one in the hi Vis style for Bike Commuting.
