The Mk2 / Mk2A is a lightweight flying suit made from linen huckaback. Itended for summer use or warm climates.
These suits are labelled as both Mk2 and Mk2A. The difference between the two designations is that when slots in the lower leg are opened up to pass leg restraint garters though (for ejection seat aircraft), the designation is Mk2A; when the slots are left stitched up, the designation is simply Mk2.
This suit has been modified by replacing the pocket buttons with velcro.
This interesting extract identifies the intended uses of the pockets.
