Rated 5 out of 5 by from Works Perfectly My brother and I each have one of these. We recently used them when hiking near Grewingk Glacier located in Kachemak Bay State Park on the Kenai Peninsula of Alaska. The trails there are pretty tough with rocks and trees and tall grass. It was raining most of a day and night and the pack cover endured branches scraping across it and all kinds of abuse. My pack and gear stayed dry, and the pack cover covered everything including the sleeping pad strapped to the bottom. Afterward I let it air dry and packed it right back in it's carrying bag, and popped it right back in my backpacks top lid for another rainy day or night. Great item.

Rated 5 out of 5 by from Excellent Ultralight Raincover My son used this on a weeklong backpacking trip in Sequoia NP and the Golden Trout Wilderness. It rained on us all of one day and part of another. This cover did a great job of shedding the rain and the size and weight are outstanding. Elastic cord cinches it around the whole pack easily. The buckle and strap it has connects just above the lumbar pad on a pack and really holds the cover in place, even in strong winds. The tradeoff is that you do have to unbuckle to get the cover off to access something under the bottom half of the cover. Also, over the long term, you probably need to be careful setting the pack down and picking it up with the cover on because the silnylon material may abrade more easily that a heavier cover.

Rated 2 out of 5 by from fragile and ineffective Got this pack cover for an extended Appalachian Trail hike and it didn't hold up well at all. After just a few days it had several tears and abrasions just from setting bag down on the ground. Also tears on the sides from brush and trees (and the AT is mostly a well-maintained trail). But worst of all, after several hours of heavy rain, the cover was completely saturated both inside and out. It doesn't fit the curved shape of my Osprey Aura very well; it's better for traditional-shaped (verticle) backpacks. It doesn't repair well because nothing will stick to it. I think I'd prefer a cover that weighs a little more but is reliable in the field. Or just stick with the tried-and-true trash compactor garbage bag on the inside of the pack.

Rated 5 out of 5 by from Lightweight, compact, effective The Medium-size cover comfortably fits over a North Face Terra 65 pack with gear lashed externally to both the bottom and sides. (Also works with the women's Terra 55 in the same configuration.) Rolls up into the attached sack a little smaller than a ball of socks, and stores easily in external pockets. The clips about 1/4 the way up from the cover bottom stretch nicely to add extra security around the "fat" area of the pack. There is an additional top clip which slings over and attaches to the pack carrying handle. Have had zero problems with saturation or leaks, even in the brutal downpours of Central America. I have not experienced any of the tearing issues that are reported in other reviews either. Maybe just lucky, but I routinely lay this cover out as a protective "table" on the ground to drop stuff on while I am setting up camp. No rips or scuffs to date. Definitely would recommend this cover to a friend.

Rated 4 out of 5 by from Great add to far! Father's Day Hike on AT...It wasn't raining at bedtime, but my son decided to cover packs anyway. Storm rolled in over night and this pack cover did it's job. Putting on the pack cover overnight will now be SOP.

Rated 4 out of 5 by from good to go... I have had regular back backs over the years that have been good good at protecting your gear.. about a year or so ago i Switched over to one of the specialized computer back packs by "outdoor products".. while I like the internal organization of the pack.. it has several shortcomings, one of which is it doesn't hold the wet back well.. which is deadly for a computer gear bag.. recently I got caught out in a bad storm and when I surveyed the interior it was wet enough to prompt me to look for a cover... when I went into the store there were about 4 types of bags. this was one of the most expensive... but the silicone exterior is what sold me in that it works beautifully with the stuff sack... strongly recommend it...

Rated 2 out of 5 by from Rips Easy I got this with my backpack last year. I used it a philmont boy scout ranch. I thought this would be a good choice because it is light and compact. The second day on the trail it ripped when i set my pack (with the cover on)on the ground. This was very dissapointing. I tried to patch it up but nothing stuck to it. I am lucky that it did not rain anymore that trek. I wish I got a more abrasion resistant pack cover.

Rated 2 out of 5 by from Fragile, Lightweight, Compact, and Spendy I used this cover on three rainy days of a month-long trip. Extremely lightweight and compact when stuffed into its own attached stuff sack. The strap at the bottom of cover and the clip at the top of cover helps to keep the cover positioned on the pack well. However, rain still gets into/on the pack through the sides where elastic cover sits close to pack edge. So, you still need put all gear you don’t want wet into separate waterproof bags. The cover is extremely fragile. Simply setting the pack on any non-grassy ground will result in abrasions and tears. I haven’t found a repair solution for the holes.

Hello- will this pack cover accommodate an Osprey 50 (Aura)? Ideally, I would like something to accommodate my 50 and 36 packs. Thank you.

Asked by: Brick1
The medium sized cover is designed to fit packs from about 51 to 70 liters. It would be too big for your packs, especially your small one. A better choice would be the small, item #757908, which is for packs about 30 to 50 liters. It would be a close fit for your larger pack, but would still work. To see the small:
