Osprey Packs UL Raincover (Large)

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.)

Reviews - Osprey Packs UL Raincover (Large)

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!

Osprey Pack Cover Atmos 65
This pack cover works great. It does the job by keeping the rain out. Suggestion; buy the next size down. They run very big. My son's small fits my large pack just fine, even when full!

Sizing Chart

All Osprey packs, save the transit bags, are available in multiple sizes to fit a range of torso lengths. To find your torso length, have a friend measure your back along the spine from the level of your iliac crest (the top of your hipbones) to your C7 (the knobby bone at the base of your neck).

To determine your hipbelt size measure around your hips, not your waist. A properly fitted hipbelt rides centered over the hipbones and needs to be very snug; after all it will be carrying the bulk of the pack's weight. The padded portion should wrap well around your hips, leaving a gap of 3 to 6 inches between the tips of the pads when securely tightened.

Nearly all Osprey hipbelts use an exclusive ErgoPull design. It creates mechanical advantage to provide extra leverage in cinching down the hipbelt. The ErgoPull design also draws tension along the top and bottom of the belt, not through the center, so it distributes pressure more evenly over the padding and relieves direct pressure on the hipbones.

Step 3 - Harness

Osprey Crescent & Luna, Aether & Ariel and Waypoint packs offer interchangeable shoulder harnesses. Harness sizing usually corresponds to pack size, but your best bet is to try one on. A properly fit harness should terminate 2 to 3" beneath the armpit. Webbing should not touch the body. By breaking the hook and loop connection and sliding the harness up and down the backpanel the torso length can be adjusted up to 3". (see illustration).

Once you have the correct size pack, harness and hipbelt, and the torso length set properly, it's time to put some weight in the pack (20 to 30 pounds of well distributed weight will do) and dial in the fit. First, snug down the hipbelt and harness. Connect the sternum strap (A) - position it about 2 inches below your collarbones and snug it down lightly. Finally, tighten the load lifter straps to draw the load solidly against your back. The lift straps (B) should come off your shoulders at a 45 to 60 degree angle in Osprey's ReCurve and Ethereal Suspension packs. In other models these straps serve more as compression straps and ride flatter; they may even angle downwards.

In a good fit, there should be no pressure points and no gaps between your body and the pack. With Osprey's ReCurve packs, final tweaking may involve custom fitting the aluminum stays to your back.
