I am very happy with this bi swing back. It recloses perfectly. There is no elastic pulling it closed. and it is so easy and comfortable. I will post a video of its performance tomorrow. Sleeves are in also . It fits me perfectly so if my customer dose not want it ( he can't wait ) I will happily wear it forever. Look for video.
( I missed the plaid on the center seam , as you can see , but I took it apart and re-sewed it. All for less than an eighth of an inch. But it matters )
