The basic technical jacket block has been created to eliminate seams in the yoke / overarm area.

The basic yoke line is straight and easily tape seamed. The basic collar can be adapted as for casual wear to suit the intended use.

If a hood is to be inserted into the collar, allowance must be added. The detail of the development will relate to the identified requirements of the end user. See examples of developments shown.

For maximum movement the garment should be tailored to the shape of the body with sufficient length calculated for sleeve, cross back and under arm, with links in extreme positions.
