klinjo hi.I just use heavy duty snaps from the local Joann Fabrics.Cost $5.00 for 7 pairs of heavy duty snaps.I attach them to the back armor with J-B KWIK Weld.It sets in 4 minutes and ready for heavy use in 24 hrs or less.When attaching only velcro I use Indutrial strenth velcro and use contact cement by DAP brush it on both sides,leave it set for 5 minutes then attach the two pieces together and they are STUCK!!!!! I took my armor off to show how I did mine hope this helps,Jeff
