Each of the refastenable side seams is a dual side seam that includes a standing butt seam formed between a front lap seam and a back lap seam.

The topstitching of the felled seam will be sewn in two stages, from the sleeve, and when this is no longer possible, from your hem.

Accordingly, the line of stitches in an overlapped sewn seam will not define the edge of the respective components [see Appendix C (3) and (4)].

Each of the refastenable side seams includes a lap side seam, which puts the seams under shearing strain during use, as opposed to peel forces.

Note that the felled seam is quite possible on an armhole, if you opt for a Japanese style: in other words, you sew your sleeve, and then you close, on the same seam, your sleeve and side.

Their construction is solid and very durable.Danner uses a stitchdown construction, which increases stability for your feet and makes the boot recraftable(again something I should probably do with my boots).
