Size A 210 denier but thread measuring over 230 denier, very strong with about 60 oz. breaking strength; good for jigs, poppers and saltwater flies. 100 yd. spools.
This 210D thread is very strong and the color choices are really good. I use this exclusively on larger Clousers where you really need to tie in the eyes and finish the heads with a firm, strong tie. You will not be disappointed.
