"I've had my Yukon for a year or two.
It 's an external frame with only 3200 cu. in, which I always think is too small. It is a great pack for young backpackers, in size, price, and quality. The only thing I don't like about it is that it's small."
"I hike mainly in the Olympic and Cascade mountains in Washington State. I still love the ever-reliable external frame backpacks. I just bought a Yukon 3500 and I love this pack. If you know how to pack and don't have a lot of big, heavy, gear, then it's just right for 3-4 days of hiking. Anything more and you will need a bigger pack. It is very comfortable to wear with thick padding on the waist and shoulder straps. It has an internal hydration pouch with two holes right behind your head to run the water tube out, and the gear separator is great because it lets you pack stuff in the bottom of the pack for easy access from the outside without having all of your other gear spill out the bottom of your pack. If your planning on 3-4 day hikes, then this is your pack."
"good for young backpackers. i used this pack in boyscouts for the backpacking metit badge. i had problems with it but that was because i was way to skinny. just about anyone but me could have used it and be just fine. i eventually grew into it and it was great, especially for heavy loads. i remember being the packhorse and having to carry close fifty pounds in the pack (heavy for a 12-13 yr old) and i was fine. Kelty in my opinion is the best backpack maufacturer out there. they make extremely durable products. however, this pack gets a four because of comfort not being extremely great."
"Do some hiking and notice that the people who've kept their old packs are the people with Kelty packs. The Yukon frame is adjustable to fit one's back and the load size is underrated. With the current fad being ultra lite a new hiker will likely overlook the comfort of a Kelty. In the long run, or walk, the Kelty is more comfortable and kind to one's body. I've done about 550 mi. with mine - I've tried other packs but missed the Yukon. I'll be doing 770 mi. this spring with the Yukon!"
