After receiving the Mystery Ranch Metcalf pack through Guidefitter, I immediately started training with it as my number 1 piece of equipment in an Elk Backcountry Training Program. I loaded the Metcalf with a 25lb sand bag and went to work. During my training this pack has been tossed on and off several times with ease, handling all the stresses. I have been rucking several miles a week and the Metcalf has been extremely comfortable. I was concerned about how it would fit and handle weight because at age 56 I have had 3 back surgeries. With the Metcalf I have had no pain. I have been so excited to train and take it on my first hunt. Just recently I had an archery hunt in Arkansas and the Metcalf was packed and ready to go. I had it loaded down with my daily hunting gear and some survival gear and it was very comfortable. It wasn't fully loaded but I could tighten the pack with all the straps to keep it perfect to size and balanced well. With a few Zoid bags for my gear, it was very organized and easy to get to. I didn't have the opportunity to pack out a deer but I am very excited to pack out an elk this coming season from a spike camp. With getting older, the Metcalf allows me to keep up with the younger hunters on pack out trips. The Metcalf has given me extreme confidence I can get the job done.
