Solution for thin people to tighten the vest

I can associate myself with the previous reviews. The processing of the vest is very high. She is with me (1.7m; 68kg; 85-90cm girth) good on the shoulder, has no pressure or scratch sites.
My point deduction is based on the two fastening straps, where the manufacturer has room for improvement (improvement needed).

I think it is generally impractical, that you have to tighten the jacket at the back, with a little practice, however, this is feasible.

I also had problems, the vest to tighten properly because the counterparts of the Velcro fasteners were on the "wrong" points (ie, the velcro has overlapped only slightly). To use the vest still useful, I have center back reingemacht each a figure eight knot at the fastening straps. This has the belt as far as shortened with me that the Velcro fasteners good overlap. The node does not interfere and can be hidden under the belt guide (between the rear weights).
