Leather Guitar Strap. This is a handmade and totally unique guitar strap made by myself at One Off Leather. I have used black calf leather and different coloured calf and kid to create this unique look. The lining of the strap is a beautiful red soft sheep akin (not woolly!) The strap is totally adjustable for your comfort from 44 to 54 inches. The strap is 2 3/4 inches wide and under 1/8 inch thick, giving it a slimmer feel than most ready made leather straps but still is very strong. Leather softens with use and age and this strap will last for years and feel like an 'old friend'. All the leather that I use is a bi-product of the food industry and no animal has been farmed just for their skin. As a vegetarian animal lover, this is important to me.
