Salzmann Reflective Backpack Cover | High Visibility, Waterproof & Weatherproof | Ideal for Cycling, Running & Hiking | Made with 3M Scotchlite

I was worried this would fit on my giant under armor backpack but it does. Makes me feel safer and keeps my stuff dry.

Can I give this 10 stars? I got this to put over my FENRUIEN 17.3-Inch Hard Shell Laptop Backpack just in case I got stuck in a downpour or had to walk home in the dark in the winter. Wow is the white triangle cover really, really, really reflective! It picks up any light and just glows like you’ve got some alien light on you! I was standing at an unsafe dark bus stop on the side of an extremely busy street and normally buses just whiz by you if they don’t see you and don’t flag them down first. Every bus stopped without me even flagging them (even buses I didn’t need!) & asked if I needed the ride because they could see this reflection at this very dark stop. I also had to walk a mile in the dark up a dimly lit street with cars driving by, and I could tell they were actively avoiding me once their headlights hit the reflective cover. It’s easy to slip on and off and stays on with two adjustable snaps straps and elastic opening, but depending on the backpack’s style it might conflict with the straps (but if it’s rain you’re worried about, the top of the backpack will be covered if you strap it criss-cross maybe). It’s easy to scrunch or fold up and tuck into your backpack when done (about the size of a med-lg coffee paper cup). It should fit over a soft baggy backpack easily, fits my hard shell perfect. If you need one for a bike/scooter ride or jog or fishing - If you want to be seen, I cannot recommend this one enough! The best thing is it doesn’t need batteries like some LED harnesses or bike lights do (obey state laws on bicycle lights please, this is not a replacement for lights that help you see or others see you, it just REALLY helps others see YOU. It does not give off light like a flashlight.)

I got the silver triangle one in standard size (up to 36L) and it has super high reflectivity. I feel seen at night! It has protected my backpack from light drizzle and moderate rain. I have a Fjallräven Kånken 17" laptop bag (20L) and the standard size rain cover fits perfectly. My laptop and iPad were protected when I walked short distances, up to 10 minutes between classroom buildings (never tried walking longer than that in the rain with a laptop).Silver triangle version doesn't have the mesh pocket, but it has the Salzmann logo which can be used as a loop for carabiner attachment. There are two elastic straps that can be buckled and tightened to keep the rain cover snug against your backpack. There is a loop that you thread the top strap through (if you want) to keep it extra, extra secure. If I want easy access to my backpack, I leave the top strap unthreaded so I can just stretch the elastic around the cover and pull the rain cover back to expose the top of my backpack.This is a very cheap investment that protects my expensive electronics from the elements without having to buy a fancy waterproof backpack. Added bonus that I am very visible at night when returning home at the end of my commute. Highly recommend using this reflective rain cover even when there's no precipitation!

Good water protection and night visibility safety. Perfect fit. Keeps backpack content dry.Must remove top half of cover to access backpack content as cover has no openings.Recommend if you don’t have a waterproof back pack. Needs visibility items for front view at night. Back view is good

This has been great for walking in the rain.

It is completely made of reflective material, giving great visibility on cloudy days or at night.

Covers a range of backpack sizes - including a smaller day pack- without being ungainly or coming off. Just test run it in the rain the last three days and it certainly met the water proof claim handily! Makes biking a safer and more viable commuting option

For safety, this backpack raincoat is stunning. In normal daylight, it doesn't appear reflective or bright. I could not imagine it could be seen, but in dark with light on it, it is bright! The size is very good too, easy to put around my backpack.
