First off, let me say that there is NOTHING light about either one of these packs. They are not super heavy for what they are (A large daypack and an expedition/extended trip pack) but they do not fall under the "light" category either in my opinion.
That being said, Kelty continues to be my favorite backpack company. I bought the redwing 3100 about two years ago to use as a 3-4 day pack. It is practically indestructable. I have put that backpack through the ringer and it barely has any signs of wear on it. While hiking in castle craigs, CA last year, I lost my footing and slid down the side of a craggy/rocky hill for about 20 feet on my back. I ripped my *ahem* ripstop pants but to my amazement, my pack didn't have a scratch on it! Ever since, Kelty has been my favorite pack company.
The red cloud is a monster! It's not very lightweight (about 6.1 lbs) but considering how much it can hold, it's not bad. I'm 6'3 and 320 lbs myself, so I require a little larger of a pack to both fit my frame and hold my larger clothing. Weight of the pack doesn't concern me as much as the load I'm hauling. My wife bought me this pack for our anniversary. So far, I've only used it once for a trip to furnace creek, CA. The suspension system does a suprisingly good job balancing the load so it doesn't feel as heavy. I havn't had alot of experience with this pack yet, but I can tell it has the same trademark craftsmanship that turned me on to kelty packs in the first place. It's a real quality pack.
I've never had to use kelty's customer service but from what I've heard, they have so much confidence in their products, if you were to break/ruin a kelty product, they will refund/exchange it no-questions-asked.
