Shoulder Span:

Measure the distance between the tips of your shoulders to check compatibility with the armor's width.

Armhole Fit:

Measure the circumference around the widest part of your shoulder and upper arm to ensure mobility and comfort.

Adjustments:

If the armor feels too tight, scale the model slightly larger during slicing.

Design accommodates optional strapping holes for fitting customization. Use leather or elastic straps to secure the armor.
