Question: Does the large size fit in a 32" liter backpack (a Deuter ACT Trail 32 ... 66cm high, 32cm wide) ???
Document: This works great, but the MULE size don't gives you a real idea of the size of the cover, so take this into consideration: if you can fit a 15" within your backpack then it's too big for this this cover, if that is you case pick the next one on size, that would be fine for backpacks for 17" and 15" laptops.
I have a fairly fat, moderately large Swissgear laptop packpack I need to protect on the way too and from work. This medium/large is just the right size. The quality is fine. It is designed for Camelback products, but it works well for other packs.
I got the Medium/Large Camelbak Rain Cover and it fit perfectly over my fully loadedMaxpedition Condor-II BackpackIt pulls tight and doesn't pull off when you don't want it to. It hasn't torn on any rocks or sharp edges yet. It is incredibly light and makes you visible when hiking or riding in poor weather conditions. Being simple and to the point... this thing is amazing for the price.UPDATE: Purchased a second one because I got tired of moving it from one pack to the other.
It's still as yellow as it first was. It has accompanied me on the Appalachian Trail and on Mount Olympus, as well as countless smaller trips and rainy commutes to class. It fits on a regular backpack or my 60L hiking pack. I am VERY happy with it.
This cover is does exactly what it should. Im a university student using the medium/large sized cover on a standard Jansport  backpack.
Ordered the medium/large version & it fits a standard sized backpack just fine. It's working great for my brother to commute to college by bus in the rainy PNW weather. I will be ordering one for myself too.
I initially bought this for a backpacking trip along a segment of the Appalachian Trail. It did a perfect job of keeping my gear dry during the rain.Then, when I returned to school, I started riding my bike to class. I rains a lot here, and I don't have fenders, so my backpack gets soaked and a little muddy in bad weather.
I bought this to my son who goes to high school by bus. He puts this on his big backpack during pouring rain. This keeps his backpack dry without damaging his bag and books.I ordered more for my summer mountian hiking in China.It is a good price and good quailty.Everyone should have one for their children's backpack. it packable into a very small bag.
I had this lying around and I was curious if it would also fit my Osprey Raptor backpack and it did like a glove.
This is an essential when bicycling in the rainy season with a backpack. Its basically required for me since I bicycle commute year round in Seattle.This fits a large backpack quite nicely and keeps the rain out. Since it has sizing cords, it can also adjust if you have to put more in your pack.Beware if you have almost nothing in your pack though, as it could fall off when the backpack is super limp (this is how I lost my last one).
Answer: yes
