The gun dealer in NB also carries Pilla kits. The Outlaw 6 series is for larger frame heads...the Outlaw 7's are for smaller featured people, women and youth.
After 15 yrs of shooting shotgun sports, I finally got my Pilla's 2 years ago. A fellow shooter got hit very hard in the face ( working on a trap machine in the bunker )The pc of clay hit his pilla lens so hard that the bottom of the lens cut his cheek...bloody it was. Swelled up his face..blackened his surrounding eye area...NOT a scratch on those glasses at all !! Sold me right then and there !!
**personal experience here**
Also had the Tombstone glasses / 4 lens kit for 6 yrs. Gotta say, they are one tough shooting glasses !!! Couple yrs back, while at a sporting clays shoot, mine fell off my hat while walking(unnoticed)...the guy right behind me walked on them...heard the SNAP, looked down and grabbed the 2 pcs and called to me saying UH OH...when I looked at them, the arm had popped off (snap sound). I put it back on..wiped the grass and dirt off them and continued on. My SIL now uses them and loves them.
There's a lot of cheaper options out there, but, when you look thru the Pilla's...the difference is night and day for color, the enhancement and the definition in the detail !
