This style of gambeson from GDFB has leather  strap and buckle front closures and semi-open armpits, providing mobility and ventilation without over-compromising protection. Crafted in heavy-duty padded quilted canvas, it has excellent blow-absorbing properties when worn separately and provides superior protection from cuts when worn under mail or plate.
