The 22mm are on the left and the 20mm are on the right. Parachute and 2 piece nylon/nato straps. I prefer them over traditional natos, less bulk. I’ve got one too many, willing to sell as a package or individually. The parachute straps are 10 Canadian a piece, The 2 piece nylons are 20 a piece. Most of them never worn. 2 or more parachute straps get 1 free. Pm with any questions or comment below. Cheers!
