Lowe Alpine Morning Star 75L+

Large single compartment, no frills, no extras, water resistant pack. Does the job well but offers little in access points.

Fit: Fits well and fits a variety of sizes. I've lent the pack to others over the past several years and everyone has said that it was a good ride.

Comfort: I find the pack is very comfortable. The hip and shoulder straps don't look like much but they have a pretty firm closed cell foam core that works pretty well. 

Capacity: This pack holds a surprising amount. It expands very well. I've had the pack carrying around 90L on several trips. I can't for the life of me find a capacity for this pack on it proper or online. I'm guessing 75 + 25?

Organization and accessibility: This pack is built to be a fortress. Things are not easily accessed but they are safe and dry. The lid is sewn on sealing out any weather from the top. Double draws on top. The pack does have 2 side pockets but they are difficult to use (straps are in the way and the zippers don't work well)

Ride: I've used it on 2-week long trips and it was a pretty nice ride both times. Lots of elevation changes, scrambling, etc. A bit heavier in the shoulders. 

Compression: The bag compresses very well, you can make it into a weekend pack without problem. 

Ease of Use: Some accessibility issues but the bag keeps your things safe and gets them from point A to B.

Construction and durability: The bag is very durable. I've beat the heck out of it and it still has plenty to give. The water resistant coating on the interior is finally giving way. The plastic extra strap mounts are starting to crack. The plastic drawstring stoppers cracked a while ago (no problem to replace them though). Weighs less than my Osprey Crescent which is 7lb. 1oz.

Conditions: Picked it up at a thrift store for a song and it's been a pack mule over the last several years.
