That is my criticism of the DCC bag too. It’s designed for a harness for Comms kit. I find it works less well than a cheap MTP lookalike daysack for general use. So I stick Comms to in it. For a weekend away I grab the PRI/Predator which fits smock, warm kit even a sleeping bag without much hassle.
Will be interesting to see what the Virtus bag is like, it sounds like there are different models of it out there.
I’ve only seen the 17L at displays. Looks like it would fit water rations an ORH and other odds and ends. A possibility if you’re dumping most of your kit in a Bergan at the patrol harbour or leaving in a vehicle. But they sell for silly money!
For some reason there are lots of the 90L Virtus Bergans on fleabay.
There’s all sorts of fancy kit out there these days at varying prices, though I have to say that for the few occasions that I’ve needed it I’ve never gone far wrong with my old issue OG infantry bergen (gained for free of course from a friendly storeman over the years).
For small carrying I just use the cheap issued black daysack (free also).
I can count on one hand the number of times I’ve worn the two bergen side pouches zipped together on the daysack yoke.
Despite of all the Gucci stuff, my favourite daysack is my Berghaus Munro, it’s simple and does the job. Just a little too small for anything substantial unfortunately.
Someone is flogging a Predator 30 on fleabay - personally I think it’s too small for a CFAV out for the day a training area - but it might be worth keeping an eye on…
I have acquired several over the years and the one I go back to / use most is the issued PLCE Infantry daysack / patrol pack. It simple, flexible and versatile, plus in my view at least, ally.
Only drawback is lack of small compartments for admin, so I have a molle pouch on mine.
If you want to wear it with belt-kit, then Dragon Supplies do superb pack that looks like a Munro but is shorter and wider. Entirely custom built - utility pouches, mesh side pockets, lid pockets, whatever you like.
If you don’t want to use it with belt-kit, then go for a Munro. You can get them in Multicam, personally however I’d go with a green one.
