I might have been better off getting the 8K, but I will just get creative on the load out, and maybe not be so high maintenance on my backcountry hunt, lol. But the bag is amazing. The weight is so easily managed, it feels much less than it is, and I am able to compare this with my ( now ) training Mystery Ranch Beartooth 80. Lots of adjustability, which I am still playing with. I had also purchased the 3K, and have moved the bags around on the frame, which is easily achievable. And everything is so.....quiet. Lastly, great tutorial support on YouTube and site!!

I replaced my 4K bag with the new 5K bag on my Initial Ascent pack system recently. I love the new design with its Horseshoe front zipper, expandable front pocket, roll top and rifle side pouch.
I am 60 years old and the Initial Ascent Pack System has improved my hunting capabilities greatly, I highly recommend!
