Replaced foam pad on my Macna Geo. Thankfully thickness didn't affect jacket fit too much and I feel I have more substantial protection. Was a very quick, easy swap. I hope this doesn't get too hot in summer. I bought at closeout for $19 so I should state that I consider this a 4.5 star rating.
3. Knox 106 Back Protector
Posted by Howard on 9th Oct 2017
This is actually the second Knox 106 back protector I've bought from STG. As always, the order was handled with speed and accuracy. This particular back protector fits the back pocket in jackets made by Triumph, and matches the Knox shoulder and elbow CE armor already installed. Fit has been perfect so there's no trimming required.
4. Knox 106 Back Protector Pad
Posted by Howard on 30th Sep 2017
Knox is probably the premier manufacturer of CE armor. Their part 106 fits the back pockets in most Triumph jackets perfectly, with no trimming required. The shoulder and elbow armor originally included with these jackets is made by Knox, as well.
5. Fits perfectly, could be perforated
Posted by Kyle D. on 1st Jun 2016
I bought this back pad to fit into my Scorpion SJ2 I purchased on this page. The part number 65 fits perfectly into the jacket pocket for those who are reading this or have that jacket and wanted the upgrade from the cheapy thin foam pad that comes in the jacket.
The pad is nice and thick and fills the hole well and seems sturdy. My minus 1 star comes from the fact that it is not perforated at all. That would be a benefit for the long hot riding days especially at 6000+ feet altitude and wearing all black leather for my jacket. Having some perforations in the pad would help to let my back not sweat as much and air out better.
Otherwise the pad is of good quality!
6. Excellent Jacket Upgrade!
Posted by J.Hall on 23rd Mar 2016
I've bought several of these KNOX back protectors to replace the standard ones in my jackets. It is a bit large and doesn't always fit the pockets, as someone else mentioned, but a good pair of scissors/shears can trim it to the right size for each jacket. I have yet to "test" one (thank God) but it is very thick and stiff and way better then that "dual density" crap.
7. doesn't fit in pocket
Posted by Unknown on 29th Jan 2016
I tried to order the SAS-TEC upgrade for my Scorpion Yosemite jacket, but it was back ordered. It was suggested that I try this, but it would not fit the pocket- too large. With the bubbles, trimming it down to size wasn't an option for me.
