Don't bother with the v4 aplix, it's the same as the v3
Can you have a look around for more bg aio's, they really are good. The organics last quite a while considering they look like a couple of bits of thin material, they don't seem to wick out the edges or anything even with the lack of anything there
but you do have to use a liner which I find annoying. Flips are good but if you're going from the AIO to these it's a big change and I don't think they're so great. Pockets are a good option really, you can stuff with anything and dry much quicker than the aio's and especially the organics.
