I currently have a demo flex vest but I can not find a comfortable fit.
I have made a scribble to help explain. I am used to operating my U2 vest so this is completely alien.
At the moment it feels like (when loaded) it hangs on to the top front curve of my hip bone area. When the vest is closed, there is no more space left on the ratchets to close further. It has a slight bias to angling the top towards in instead of out. I have worn the vest for a few hours tops but I have been told that it is not uncommon to tighten up as the day continues because of foam warming. I have all supplied foam in the vest.
When I was wearing the vest I was also curious of where the back section foam/frame should be in contact with you. It seems like its the two hips + the lumbar area as I feel the sides are only slightly away from my sides, is this the same for you?
