OR – Ventra Gear – Main Frame

Ventra Gear’s patent pending Main Frame adapts to many frameless packs and offers some breathing room between the wearer and the pack’s bag thanks to the mesh back. Inventor Mike Wright is a Mechanical Engineer who created the Main Frame specifically for this reason, commuting to work each day on his bike and arriving with a sweaty back.  

I saw it and immediately thought “jungle” but this easily removable frame could also give some structure to otherwise floppy assault packs or be adapted for use as a frame sheet for odd sized loads. In fact, the Main Frame is rated for use up to 60 lbs loads yet weighs only 333grams/11.7 oz for a size Medium. It uses the shoulder straps from the attached pack and Mike offers an optional waist belt for those packs that don’t have one, The frame is offered in Small Medium and Large and will be available soon.

    At the risk of sounding sexually attracted to a backpack… that is fucking hot. Or specifically not hot, therefore amazing.

    I need to dig the pack out but that looks a lot like an old sierra designs DCU day pack I have sitting in a box in the garage

    You gotta love us. Dude made a product for bike commuting and our first thought upon seeing it is “jungle warfare”.

      As well it should be. I don’t care as much about what it was made for as what I’m going to use it for!

      The Camelbak was originally developed for cyclists, too.

    First thing I was wondering was if you could put an LC-2 ALICE on it…

    I can see the SEALs rigging their Yotes up to these. Looks really promising

    Looks, to me, a little further off the back than may be optimal for walking. Bent over on wheels, great.

    Someone let us know.

    I tested this on my Spec Ops pack and hiked up Bishop’s Peak in San Luis Obispo, CA. As a former Marine and now Wildland Fire Fighter, I was interested in the durability of the frame, so I packed it with 50lbs of weight and did a death march up and down the mountain. This not only supported my back it provided a nice cool airflow that would otherwise be a hot from the contact with the backpack. The waist strap it came with me really secured the frame to me when running and jumping from rock to rock. I’ve yet to try and attach a sidearm to it but might be a good conceal spot when hiking in wilderness and national forests.
