Question: Is it a pack of two covers?
Document: I purchased these two backpack covers with the intention of using them to cover two carry-on suitcases. (I thought the regular suitcase covers were too expensive.) I cut holes for the 4 spin wheels and sealed the holes with black duct tape (completely unnoticeable) and they covered the suitcases splendidly. I used them to cover the suitcases that we travelled with through big cities, crowds, subways, buses, etc., to keep wandering hands away from our suitcases.
Great cover at a great price. I use this on my Deuter 45 10. It fits very well and is easy to get on and off. The fabric is much denser than I thought it would be. My fellow climbers suggested that I use a garbage bag to put everything into and then put it inside my pack. Seriously? The quality of this cover is as good or better than all of the other covers I researched. It is a steal!
Fits my 65 pack nice. Great addition to the pack. Should hold up well in the wet forest in Washington.
Simple design -- its just a bag. It does the job & fully and properly protects my backpack when biking, its compact, and as such is ready for use at any time. Saved me having to spend a lot of money on a waterproof back pack
We just took them off (easy off and easy on drawstring & lightweight to store) when going through customs on an airplane. I highly recommend them. We'll use them again on our next trip.
This item fits perfectly on my North Face Overhaul 40. I traveled in dusty, rainy, hot/cold environments overseas and this product was more than equal to the task. I highly recommmend this product!
This is the product i was looking for my 35L backpack for the rainy season. In fact on the high mountains you do not have to wait rainy season for rain! This is a good quality and comes with a nice logo so surely the company must have made it with quality.It has nice finishing and light in weight. This is also generously big size in Medium and the material is good. If you travel and track on mountains with your backpack you must need this.
The sizing and fit of this cover is exactly at as stated in the description. A good purchase! It fits very nicely in a side pocket.
So, this item is too big for my 15&#34; laptop backpack. I'll be working in working in a region with random summer showers and wanted to have this handy to protect my bag and computer. I'm actually going to scotch-guard the backpack too, but wanted this as a main protector. I ordered Medium, and it is wayyyyy too big. Way too big. If you want this for a standard sized backpack, you should probably go for small or ask the seller first.
Otherwise, I'm sure it's a great product and I will still try to use it. I'll update it if I get to use it.
Answer: yes
