Customer Reviews
Just got the mainframe with the Vapor 7500. Very satisfied with the quality and functionality of the whole system. Did a 15 mile overnighter loaded with about 60 lbs of gear for myself and my kids and the frame held the weight beautifully. Very comfortable and stable.
Well worth the money took a hike up the mountain about 2 miles somewhere around 45 pounds on, very comfortable love it.
The frame is great and matched with a vapor pack it’s on point!
Bought the F1 mainframe with 2 batwings as a base for a daypack/meat hauler. Very comfortable and rock solid even under a heavy load. Tons of versatility. Only downside I’ve noticed is that there is a loop to hook the zipper on one side and not the other, noticed the zipper coming down on the one side after stuffing items behind the batwing a few times. Easy fix and can rig your own d ring as a fix but would have been nice if it came set up already.
A great gear and appears to be robust, however, it needed a little bit of exposure to actual field use ie bushcraft, in order to have a thorough and honest review. But for now it could really get a little bit of longer straps to really strap items that were shown in the prom videos.
I decided I was going to start pack in hunting on public land as an alternative to my standard lease hunting I’m used to. Buddies told me the first thing I need is a good pack. After some research, I settled on the Eberlestock F1 Mainframe. I outfitted mine with two batwing packs and am absolutely impressed with the construction. The M1 Mainframe allows for many different pack configurations and I can’t wait to add to mine. I highly recommend this pack.
Have not used it yet but very happy looks like it will work out well
Best mainframe I’ve ever bought
Great product. Can’t wait to take it out in October.
so i have had the F1 for several weeks.
been using it as EDC catch all for all my daily gear...along w/also trying to cram anything I can get to fit in current configuration i have found to be most useful for daily use.
hard daily use dragging to sawmill in SE/Ark every day...thrown on the ground / on the floor...carried in front seat of truck & goes everywhere I go...I'm intentionally hard on it
first 2 days of use the coating was peeling on bottom w/just my thumbnail scraping off...had I continued I'm confident i could completely flake off the entire thing w/just my thumb...it's aluminum so it's not gonna hurt to have exposed metal...but the coating is a mark against the frame
the strap / hook up system i'm not completely crazy about...you absolutely have to roll up excess strap or it will slip...or strap at angles that will bind the strap better.
would really really like to be able to have access to frame...feels like missed opportunity / potential to only be able to use hook up points & not be able to put a zip tie or bungee around actual frame
other than just minor complaints the frame is stellar & has far more untapped potential that what i have been using it for...looking forward to many kayak / backpacking trips as well as many more days as daily carry.
so here is a personal request to eberlestock...I affixed a old NIKE drawstring back pack w/grommet corners...when empty weighs nothing and lays flat against frame...but when zip tied to frame makes for an incredibly useful pouch...then w/the laser cut panel you can secure all bigger things...I can also reach over into pouch while driving or parked...reach into pouch & fish out anything I need w/out having to zip/unzip a anything
but a draw string type pouch made out of same kind of material as laser cut panel would be incredible...ability to un hook your panel pouch w/all your smaller items throw it on & go...
