I ordered the Approach and the Palisades dog packs as I wasn't sure which one would be best. I am actually returning the Approach bag, but I have to say it's not because it isn't a great bag.
Reasons why the Approach bag is great:
*It holds a ton of stuff, (about the same volume as the Palisades)
*The same sturdy harness system as the Palisades
*Same great quality and construction as the Palisades
*Same great reflective piping as the Palasades
*Two nice storage sections per bag
*Same great fit and lots of adjustability as the Palasades
Why I chose the Palisades dog bag over the Approach:
1) I'm a gear/tech junky and I super love that you can remove the bags from the harness (The bags don't come off the Approach.)
2) I live in the PNW, where it rains literally 8 months out of the year, so the water proof zippers are a suuuper nice bonus, (though ruffwear does make a nice waterproof cover you can put over the Approach pack.)
3) I love that the Palisades has an extra interior pouch that you can put the water pouches in (The Approach does not come with two water pouches for your pooch like the Palasades does.)
Honestly, I think both the Palisades and the Approach packs are really great bags and you can't go wrong with either of them, I just love the ability to remove the bags from the harness and love the water bottles/water bottle pouches.
I purchased the size medium and small to try on my 50 lb pit/boxer/something mix as he's sort of between sizes being a leggy, skinny boy who isn't muscled like the average pit. The small fit, but didn't leave any room for my two year old to grow as the stomach straps were maxed out. The medium allowed for ample room for him to get fatter, or possibly fill out more, (he's two.) I kept the size medium.
We've been on three walks that had weight in the bags and the bag stayed in place very well, and my dog seems to be pretty excited about putting the pack on each time!!!
