Although most backpacks feature waterproof fabrics, they all have lots of seams and zippers where water has a tendency to work its way in. The Osprey UL Raincover (Medium) blocks this seepage with ultralight silicon impregnated ripstop nylon and fully taped seams.


  • Fabric: 40 denier silnylon (silicon impregnated ripstop nylon). Fully seam taped
  • Drawstring closure with toggle tightener for a secure fit
  • Built in storage bag
  • Fits packs ranging from 2400-4300 cubic inches (40-70 l)
  • Weight: 4.25 oz. (0.12 kg.)

Purchased this cover to fit over a 3400 ci. pack and it does that with room to spare (no gear attached to outside pack). Hiked through a moderate rain storm for several hours and only sign of moisture seepage was from sitting the pack down causing contact between the bottom of pack and the wet cover. Very lightweight and stuffs into a fixed pocket on the cover which gives you one less thing to lose. Drawstring and snap closure keep it in place on the pack. Alternatives: if you are willing to sacrifice weight for durability purchase a cover with a reinforced bottom (100D+). This 40D will not withstand too much dragging across rough surfaces.

Pros: Great design, Build quality, Ease of use, Great value, Cons: Wears quickly

Even if I'm not that dry, at least all my stuff will be!

I like the way the Osprey raincover looks and functions at the same time. I got a medium and I have a 60Liter bag. There's some extra space yet, so I can strap on my sleeping pad and my shoes outside my backpack and I know everything is gong to fit and stay dry in the rain.

great waterproof cover

Medium fits my Osprey atmos 65~! It does its job. It also stretches a little bit and most of all keeps my stuff DRY~ I would definitely recommend this product.

Pros: Build quality, Performance, Ease of use

Kept My Stuff Dry Multiple Times!

This pack cover is great, it's lightweight, packs small and the material is durable enough that it won't easily tear on branches, snags etc. It also cinches tight around the pack and buttons on to keep it around your pack. I had a friend who lost a pack cover in windy conditions because it didn't strap around the pack! This cover saved my belongings from getting wet on multiple hikes in serious downpours. I use a size medium with my Osprey Aether 70 and it fits great. I like the fact that it is a little roomy because I keep my sleeping mat on the outside of my pack and it fits around no problem.


Another great Osprey product.

A great design that has the ability to stretch over lashed on gear. Osprey products have been consistent winners.

Fits Great Looks even better.

This rain cover was a great fit for my Atmos 65 pack. And whats better it looks great too. Its also rather simplistic not difficult to use.


Medium Fits my Aether 70 Fine

Does what a good pack cover should. Major upgrade over a garbage bag. Packs down small and is lightweight.
