      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.

      This pack is Awesome

      Bought this pack for packing out meat, but in the meantime, I have been using it to pack out wood from a remote area. It's sturdy and fits well on the back. Straps are solid and has Velcro to tie back the excess, so nothing is dragging. After using it a couple of times I ended up buying the batwings also. I packed a chainsaw on it while I rode a horse out on the trail to cut a fallen tree. Surprisingly the pack fit perfect on my back while sitting in the saddle. Something I don't normally do but it's nice to know I can comfortably ride wearing the pack if needed. If you are looking for a frame pack, this is the one to buy.

      F1 is THE frame!

      Love this thing! This is one of the core reasons I've converted to Eberlestock, the modular design and durability are other reasons. The frames ability to quickly be adjusted on the fly, makes it leader of the pack. I'll likely be picking up a secondary frame after this season. Don't second guess it, drop it in your basket!

      Thanks for the prompt product delivery. It looks good and I’m looking forward to trying it out in a few weeks during elk season.

      Fits a lot better than I thought it would. Being an over 50 former infantry soldier I believe this frame with the scabbard and pack will serve me well on my upcoming New Mexico elk hunt. It’ll perform better than I will! 😎

      This is my second F1pack. I was very impressed that I bought this second pack for my son. I’m still waiting for the dry earth batwings to come off of back order so I can order those for him as well.

      Versatile and light.

      Versatile and light, just as promised. The modularity feature allows me to reconfigure for the style of hunt I’ll be doing. I haven’t just set-and forget- with this, with the ability to dial up or down with components is impressive. Have yet to get the vapor addition, so far the bow sling works great. Have yet to use the rifle scabbard as it’s early in the season.

      F1 initial thoughts.

      I recently got an opportunity to use the pack along with the 2500 vapor bag assisting on a hunt. I transferred everything from my old pack and loaded as I would for a normal day hunt. After hunting all day I was very impressed with how much lighter my pack felt even though I hadn’t changed anything. I was using an old badlands 2500 and the difference was night and day. It fit great, wasn’t bulky, and I had no problem sneaking through the north Idaho brush. It’s hard to not give it 5 stars, but a reverse tightening system on the hip belt would make this thing perfect. Looking forward to getting it bloody shortly.
