Thumbs Up:
- The feature I like the most about this is easy access points to your pack. No matter where you stuffed it, you can get to it in matter of seconds. Good for organization-freaks as well as messy-campers!
- I have used this pack in snow, in heavy rain as well. I use Gregory rain cover, but even without it, it provided pretty good waterproofing.
- Adjustable shoulder straps are very comfortable and I didn't feel the pack even when I was carrying a week-long worth stuff in it.

Thumbs Down:
- Side water-bottle holder is not convenient. My Nalgene kept falling out of it and I had to just stop using it.

Overall:
But overall, I am pretty happy with this pack and I definitely recommend this to any serious hiker. It's pricy of course, but you get what you paid for.

This is an extremely comfortable pack that carries heavy weight extremely well. The numerous access panels on the pack are a real plus....no need for dumping out everything in your pack to find something. I love the separate pocket for a sleeping bag, but even better the fact that the bottom of the pack is made of rubber, which is essential if you’re carrying a down sleeping bag that has to stay dry. From the hydration pocket, to the rubber bottom, to the numerous access panels, this is well thought out pack. This bag is ideal for anyone traveling long distances, or with lots of weight. I Love my Whitney!!!

Whoa! Comfortable, comfortable, comfortable. I just purchased the Whitney and although I thought it was kinda pricey, now I can see why. The waist belt, shoulder harness, and shock absorbing chest strap are all designed with comfort, and more importantly, support in mind. The only reason this backback didn't get a "5" in my book is because the barn door side pockets are kinda funky. I don't understand why Gregory put the compression straps over the tops of the side bags!! Also the front panel pocket is smaller than I anticipated. However the comfort trade-off is more than worth it (note: I'm an organization freak). Highly recommend this pack primarily due to comfort/support; I could have hiked double the miles I'm used to just because I couldn't feel the Whitney on my back!!!! I can tell after just one weekend in the Smokies that this puppy will last forever!!!!

So far I say this pack is awesome. Lots of pockets. I wish a more detailed owners manual came with the pack. It would be cool if they told you why it was designed the way it was. What they intended everything to hold.

Excellent pack and features. Pricey, but you get what you pay for.

Having a tall and lean body type, I found that I needed medium length belt pads (recommended for a 34 inch max waist/hip measurement) vs. the large length belt pads (recommended for a 34 inch min waist/hip measurement) that come standard with the large backpack frame size. Gregory Customer Service was helpful and very quick in replacing my (slightly used) belt pads with the smaller size.
