At only 4.5 ounces, the Osprey UL Raincover (Large) takes up very little space in your backpack yet comes up big when bad weather strikes. Taking a few moments to place this fully seam taped fly on your pack when the first drops fall is much better than spending a whole day post-storm spreading your gear out on rocks waiting for everything to dry out. On cold, clear nights, the UL Raincover (Large) also does a great job of keeping dew and frost off your backpack.


  • 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 3600 cubic inches (20-40 l) and up
  • Weight: 4.5 oz. (0.13 kg.)

It's a raincover
June 30, 2011

No better or worse than any other raincover on the market -- it fits my Argon backpack without any issues. When choosing a raincover, you want one that is large enough for your back at the lightest weight possible. Otherwise, they all seem to function about the same. It stuffs neatly into itself. My Stratos and Kestrel came with built-in raincovers, but for some reason, the higher end Osprey Aether and Argon do not come with raincovers.

Pros: Great design, Performance, Ease of use

well made cover

fits my Argon 85, lightweight, packs in its own attached bag

Works great!

Used this hiking the continental divide. Rained for two days straight with off and on hail. Pack cover stood up well. It was a little big for my Osprey Aether, but still functioned flawlessly. Everything inside my pack stayed dry, unlike everything outside of my pack. I was wishing I had a pack cover for myself! This works much better than garbage bags I have used in the past!

Great product!

Put off buying this for my Aether 85, but honestly shouldn't have, packs up super small and light. Couple this with something like a frogg togg suit and you have the most versatile rain system for the trail IMHO.
