One of the primary base platforms for the EMOD™ system with a constantly growing number of accessories. Build it up to be a multi-day expedition pack, or go in light so you can come out heavy.

Tested to hold more than 700 lbs., this ultra-rugged frame utilizes YKK zippers to allow the attachment of a variety of packs and accessories to fit any backcountry hunt. The F1 Mainframe™ is fully adjustable and completely user configurable with endless combinations.

ULTRALIGHT SETUPS

  • The Vapor 2500, 5000, or 7500c.i. for any length adventure with ultra-light considerations. 
  • 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 and make packing out meat simple.

MID-RANGE SETUPS

  • Pair with the Super Spike Duffel or 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. Allows for top-loading or front-loading access and use the Mainframe when it is time for some heavy lifting.

EXPEDITIONARY SETUPS

  • For a 5-10 hunt, use the new Vapor 7500. Pack all of your gear into the backcountry and when you reach camp and drop your gear, the Vapor series with collapse nicely against your frame to allow you to day hunt out of your camp.

An excellent frame

If I am to mention a single backside, it's that the metal frame is hidden inside fabric and you cannot use it directly to strap things to it, but it's just a minor flaw of a great carrying system.

Nice Pack

Would be nice to have 4 anchor points on each side. Maybe 1 top and bottom also. Otherwise nice pack! Waiting on batwings to add.

Best Frame Pack Ever!

Haven’t had a chance to use it hunting but have been using for the MTNTOUGH 45-70 Fitness program to start getting ready for next year’s Colorado hunting trip. Extremely comfortable and the customizability of this pack is next to none!

Looks good and fits good. It seems comfortable and light weight. Hopefully I will get a chance to test it out soon.

Very versatile

To be used as a back-country hauler for my portable capstan winch, and primarily as a rifle pack for regular ski trips patroling the property. Excellent quality, fit and finish.

Great pack for a female hunter

Female hunting gear is difficult to come by. I purchased this bag as a gift for a female hunter after an extensive conversation with the customer service team at eberlestock. This pack fit my girlfriend who stands at 5'6" and 130lbs at best. I must point out that I don't own one of these myself and I was envious of how comfortable she was hauling gear in Southern Arizona.
