If you are looking for an extra set of handles for your GSO-4.1 you are in the right place.  The handles come in 3 different materials:

-Canvas is a medium cotton weave, impregnated with a phenolic resin. This coarse fabric based material has good texture, for a secure grip even in wet conditions.
-Linen is a fine cotton weave, impregnated with a phenolic resin. While not as textured a canvas, the fabric based material has good texture, for a secure grip even in wet conditions.
-G10 is a glass woven fabric, impregnated with an epoxy resin binder. The glass woven fabric itself is almost clear, so dyed G10 material exhibits very vibrant colors. Unlike Canvas and linen, the G10 handle surface is smoother and can feel somewhat slippery if your hands are oily or bloody.

Disclaimer:
-There are often variations in colors between each lot of materials.  This is especially true of the natural brown canvas and camo canvas options.  We cannot guarantee what shade you will receive with your order.
-Handle orders do not include fasteners unless you choose to add them to your order.
