    When the mountains are dripping wet, your pack will be nice and dry inside its Mountainsmith Rain Cover.

    Nothing is worse than crawling into a wet sleeping bag inside a wet tent and opening a soggy book. Keep your pack dry with the Mountainsmith Rain Cover. These waterproof covers feature full-circumference drawcords, hook-and-loop closures, and integrated stuff sacks.

    Waterproof it all

    • Familiarity: I've used it several times

    I have a favorite Pacsafe backpack for traveling (and daily use) but it isn't really "waterproof" so I got one of these to keep the rain or snow off my gear. Win Win!

    sweet stuff!

    • Familiarity: I've used it several times

    This cover is awesome, super simple and held up well in what I experienced. (just a consistent light drizzle for a few hours) Very abrasion resistant which I loved cause I am not cautious. The only downside to this is I felt that the drawchord was pretty weak, but still enough to get the job done! snag one asap!

    Great backup rain cover!

    • Familiarity: I've used it once or twice and have initial impressions

    My other rain cover tore so I picked up this one to replace it. So far it seems to protect from the rain (I have not used it in super heavy rain yet) and the large fits my Osprey 80L well enough. It's not super expensive and it gets the job done.

    Great for light to medium rain.

    • Familiarity: I've used it several times

    Pretty handy for hiking in the Pacific Northwest. Keeps my gear dry and it's light. Its held up to light to medium rain.

    I haven't been caught out in a storm or even just heavier downfall to know how well it will protect my pack. I've had this for a couple years now so far so good.

    Get the Job Done

      Although there is nothing particularly spectacular about this rain cover, it does exactly what you need it to, keeps your pack dry when you're out in the rain. I have only tested in a light drizzle that lasted for a couple of hours, but it kept my pack and more importantly, the gear inside, completely dry.

      I bought this for use with my Osprey Aether 70 (the Osprey Rain Covers in that size were out of stock) in the size L, which fits great!

      Pretty Solid

      • Familiarity: I've used it several times

      I put this pack cover through the ultimate test when backpacking in Alaska this summer. The first trip out we got caught in a torrential downpour that would have left my gear completely drenched had I not had this pack cover. The nylon taffeta material is fantastic and held up well to abrasion from bush whacking (hello Alaskan backcountry!) The only downside to this pack that I've found is the drawstring cord doesn't keep the cover very secure and was slightly irritating to adjust. That was really my only qualm with this cover. I used it on my Deuter 60 liter when it was fully expanded and purchased the size large. The fit was pretty spot on. Lastly, the integrated stuff sack is a nice feature with this rain cover (never lose another stuff sack again with this!)

      Keeps the rain off

      • Familiarity: I've used it several times

      I purchased the small size rain cover for my Golite Jam 50 Liter bag. The cover is just fine. It doesn't fit perfectly over my bag, and as such, though it has kept my bag dry during several drizzles of rain, I wouldn't expect it to hold up to an especially heavy or windy storm. As others have noted, the material doesn't feel as durable as some pack covers I've seen, but has held up well with some initial use and will work just fine in light rain.

      Great raincover

      • Familiarity: I've used it several times

      I've used this cover on several backpacking trips and it always keeps my gear totally dry, very easy to use and folds up into its own little pouch.

      Keeps your gear dry! Seams.....

      • Familiarity: I've used it several times

      I have only been caught in the rain and needed this cover 3 times this year since I bought it.

      So far it has held out even torrential rain when I have needed it.

      So far I have not had problems with the seams but they do not look the best, and I am a bit of a seam stickler so I have to knock of two stars because I highly doubt this is going to last as long as my osprey rain cover.

      Keeps bag dry, but breaks easy

      • Familiarity: I've used it several times

      I used this in a few rainstorms on my backpacking trip. My stuff stayed dry, but the plastic on the drawstring broke after just a few uses. I would spend a little extra money to buy a better made product.

      Seems good

      • Familiarity: I've used it once or twice and have initial impressions

      I haven't field tested this yet and won't for some time, but I thought I'de share my thoughts on the sizing, as that seems to be one of the biggest ambiguities prior to purchase.

      I have a 65-70 litre pack and ordered a Large because I wanted to have some extra room available for things tied externally. Large was a good choice. There is ample room for a few items to hang on the outside of the pack, yet not so much that the tarp is obnoxiously big when there is nothing attached to the pack or when it is only three-quarters full.

      Overall construction seems good- taped seems, feels durable, nice stash pouch.

      Good Bag, Bad Clip

      • Familiarity: I've used it several times

      I use this bag to protect my backpack during extremely heavy east texas rain storms. The bag keeps my backpack, containing school books and a laptop, completely dry. The only complaint I have is that the clip used to cinch down the bag, broke the first time I put any strain on it. I now just make a slip knot to hold the clip, and it works fine. I wish the clip would have lasted longer, but again, the slip knot works.

      Backpack cover

      • Familiarity: I've put it through the wringer

      Didn't work that well. Fell off as I was hiking a hard trail with it. Straps (of course) got soaked during normal wear. The part that was covered was well protected and it folds up compactly. The material is sufficiently rugged. But I will try a poncho next.

      way too small

        WAY TOO SMALL!!!

        i have a vaude 45 + 10 Liter pack, and i bought small (which is supposed to fit up to a 58 liter pack), but i had a hard time putting the rain cover over my pack when the pack was NOT that full (closer to 45 liters of volume at the time).

        Otherwise, the cover looks good.. but it doesn't fit. ORDER A SIZE UP!!! (or two..)

        Would the Extra Small fit a Maxpedition Lunada?

        the Lunada has an aprox. overall volume of 390 cubic inches. the xs is designed to fit packs at least 4 times that size. yes this rain cover would fit over it, but you'll end up with lots of extra material, and not a good fit.

        Do these fit well on a pack that has nothing sticking out above the shoulder straps? I'm running a 5.11 Tactical Rush 24 and I'm concerned the cover won't stay on.

        define well. the elastic will hold it on to the bag, but it can be pulled off and the shoulder straps will cause there to be a small gap between your back and the rain cover where rain can get in. my wife's 5.11 tactical backpack has some velcro on top, so i imagine you could modify a raincover with some stick on velcro and engineer a better system.

        I have two packs, both 30L, which seem to be inbetween Small and Xsmall. The dimensions are 24" x 12" x 6" and 21 x 11 x 6 inches. Any suggestion on which size to go with. I won't be lashing any equipment to the exterior of either bag. I would prefer a snug fit without having to cinch drawstrings, I'm just paranoid that Xsmall will be too small. thanks in advance. Also, the dimensions and capacity listed here are not the same as those listed on the manufacturer's website.

        I'm contemplating buying this for a school backpack in a rainy climate. The knapsack in question seems to be roughly 20x14x12...will a Large cover be unhelpfully loose on a stuffed knapsack, or will the Small/Medium somehow cover enough to keep all the papers/laptop dry?

        Are these really "waterproof" or the same...

        Are these really "waterproof" or the same material as the rain covers in the Mountainsmith Lumbar Packs? If so, why no lumbar pack sized covers? Fed up pre-guessing the weather and packing the contents of my Cairn 2 in poly bags to keep out the British rain.
