The arms on my specs are fairly uniform in cross section. When I use a
traditional neck cord it tend to slip off the arms. If I use sports
neck cord , the arms are attached to the cord using a neoprene sleeve
with the cord ( with a boot lace end fitting ) pushed one end of the
sleeve and the arm of the specs in the other, this again relies on
friction and again tends to fail with the cord pulling out of the
neoprene

Anyone know of a better solution ? The right sort of glue in the
sleeve perhaps ?.
