Mochila extensible multiusos - OD [8FIELDS]

A good product for the price. The sholder straps can be detached via clips. It also has a chest strap. It has a small pocket on the top and a bigger one under the top one. And there is the main compartment, that can be expanded (unzip the zipper that runs on one side, on the bottom and on the other side. In my oppinion it's big enough for a one -day mil-sim event (so 12 hours of play). It also has MOLLE straps on the front and the back of the backpack.

I travel a lot by train to my games and wanted a 2-bag solution. One weapon's case, one bag with all of my gear, as light as possible: This was my choice.

So here is what I manage to pack inside it:
Helmet w/ earpro, kneepads, GoPro, 2L waterpouch, batteries, 2 protein bars, 2 bags of BBs, Green gas, towel, Energy drink and a Speedloader w/adapter with a tiny bit of room to spare.

You might be wondering, what do I do with my rig and belt? While the buckle-up system doesn't interest me in turning my backpack into the harness for my chest rig what I can do with the system does.
Using the harness and belt I attached the rig backwards and slung it over the backpack, making it essentially another pair of pockets on top of it. I then looped the belt around the armbands of the harness and slung it over too. It all hangs securely and doesn't press against your back. Just make sure not to pack any mags, holsters, gun-ho patches or grenades on your chest rig as it will be visible to the public. The backpacks armbands are durable but do not tempt fate and overload it, think about your poor back!

If I'm playing a milsim or a game with a far-away spawn; I size it down and strap the chestrigs waistband to the backpack and unclick that if I need to get something from it. Being able to downsize it is a wonderful convenience and imperative to be comfortable during play. If it's a CQB or a sunday game, I suggest you downsize it and leave it in the safezone.

Don't get me wrong, It is a cool feature that you can make it a back panel to your rig, it's just not a practical one like with all back panels unless it's there for your teammates. But that is one redundant feature amongst a hundred other useful ones.

Highly recommend it, even more so if you run a chest rig like me.

I was struggling to get a decent solution for hydration pouch for my split front chestrig. This is it though! Since you can attach it to the molle at the shoulder back panel and it has buckles to attach it at a belt level, it fits very well and the adjustable size makes it easy to plan your load for shorter or longer games.

8Fields the best!
I was looking for backback-hydration bag for a while.
This is 2 in 1 combo!
It fits a lot of accessories as a bag when is extended, multiple pockets.
If you use it as hydration back it has the perfect size!
Also it can be carried as a rig if you only attach on the front magazines pouch!
I personally use it as hydration bag attached on my plate carrier and full with my accessories before and after the games, for transport.

This is a big boy!

The amount of space that this backpack has is huge, you can even use it for trekking or other outdoor activity, you can fit a lots of things inside and is expandable!
With some "engineering" you can even attach it to a big plate carrier

Very good and lightweight backpack I use when I play without a chestrig, i store some bbs in the back alongside with a radio on a molle ouch and a hydrationpack. Very lightweight and good. Straps can be flimsy but tightening them down sorts that out. Great little hydration-backpack hybrid.
