      ULTRALIGHT SETUPS

      • Choose the Vapor™ 25005000, or 7500 for any adventure with ultralight, multi-day performance.

      • Use 2 Batwings when you plan to go in light and come out heavy. Stay quick, light, and mobile with the Batwings. They are intuitive to use and make packing out meat simple.

      MID-RANGE SETUPS

      • Pair the Super Spike Duffel™ or the Zip-In Dry Bag with Batwings for a 2-4 day hunt. Pack all of your gear into the backcountry and when you reach camp and drop your gear, unzip the duffel or dry bag and hunt in your ultralight Batwing setup.

      • If you like the organization and function of a backpack, the new Vapor 5000 is the ideal choice for a 2-5 day trip. This pack allows for top-loading or front-loading access and then can separate from the Mainframe for game bag carriage when it’s time for some heavy lifting.

      EXPEDITIONARY SETUPS

      • For a 5-10 day hunt, use the new Vapor 7500. Pack all of your gear into the backcountry and when you reach camp and drop off your kit, the Vapor series will collapse neatly against your F1 Mainframe so you can day hunt out of your camp.

      40 lbs easy

      Now I did get it for hunting but it's not hunting season yet but part of preparing is doing hikes here in wonderful utah. Well half way my 5 year old decided it was to much walking. Now she had a wonderful seat and then strapped to the frame as well. She made it half a mile before she passed out. So a 40 lb kid strapped to the frame with 10 lbs of other things thus thing felt great. Fits snug in the shoulders and high on the hips. Comfy and great airflow. Kiddo didn't complain much either. Here is to putting in all the extra miles.

      F1 Mainframe

      Initially ordered the tall, (6’1.5” 215lbs 19” torso for comparison) and it felt like majority of the weight was sitting on my tailbone even with the pack full adjusted up. The regular out of the packaged fit perfect for my torso. Weight sat right in the small of my back. Tall seems more for the tall tall folk. Recommend the regular if you’re right on the line like myself.

      Excellent quality and comfortable

      Seems extremely durable and comfortable. I can’t wait to put it and myself to the test on an upcoming moose hunt this fall. Combined it with the bat wings and the 7200 dry bag. Boatloads of room!

      Extremely comfortable, versatile, with quality construction. I've had many packs and many hunting packs in my life and this one is the best! Glad I discovered Eberlestock!
