Mountainsmith Rain Cover extra small 

"I'm a full time student in upstate New York and it rains a lot here. I never leave without my Mountain Smith rain slick. It fits my North Face Surge pretty much perfectly and I'm thinking of getting another rain slick from Mountain Smith for my 40L pack. It keeps my things very dry, fits very securely, packs nicely into its attached mesh bag, and is made of very durable material. I highly recommend it."

"It's a nice little rain cover. Even this "extra small" is quite big and can very easily cover a medium-large backpack, so unless you're trying to cover a duffel bag, go with this size. It's a little tricky to get back in its little attached case though once you've unfolded and used it, but overall not too bad. It's also classier and nicer than bringing garbage bags with you! :-)"

"Does exactly what you want it to do. Easy and quick to cover-up backpack walking on campus. Never a wet book or paper to worry about. Great product!"

"This rain cover is perfect for protecting my backpack while walking around campus in the rain. I've only used it once so far but my books and laptop were totally dry inside my backpack. Great item and glad I got it. It should be on every new college student's list to get for college!"

"Fits my backpack well, for use in commuting and performing ecological research outside when the skies open up."

"This rain cover fits my Jansport book bag perfectly. I use this when making 100-mile trips on my motorcycle if it may rain. I used it twice through some light rain and some downpours, and everything was completely dry. It works great!"

"Really pleased with product"

"Great Product"

"Havent had a good chance to use it yet but it will serve its purpose once I do need it. It fit my bag nicely, and I'm quite confident that next time it pours on me while i bike to school, my stuff won't be wet this time."

"Very handy and practical item during rainy days. We use to cover backpack to/from school. Purchased two and one of the bags string ties broke after a few months. Wish they offered in different colors as black not a hit with the kids."
