I use this jacket for my occasional fair weather work commute or when I expect to be in traffic. After 5 months and somewhere around 1,000 miles I noticed my jacket was a little lumpy in the back. I took it off to find the back pad collapsed down on itself and broke into 3 pieces! I certainly didn't expect that out of something I purchased for the sole purpose of protection. I now have zero confidence in this back pad to actually hold up and provide any protection in a crash. It was never mistreated; I always hung the jacket in the closet or draped it over the seat of my bike and was never subjected to extreme temperatures (I live in Hawaii so 60-90*F).

Wore it in my jacket for a month; removed it to wash the jacket and noticed that it was torn in two places. I take good care of the jacket, so it appears that the insert is just not durable.

A previous reviewer compared this to the Klim D3O back protector. They are not rated to the same CE level. The ICON D3O is rated to CE level 1 (the KLIM D3O is rated CE level 2). As CE level 1 protection, it's great. I replaced the foam pad in my First Gear Kathmandu jacket with the ICON D3O with some modifications. It's a great fit and no more noticeable than the foam pad it replaced. It's about the same thickness and weight but with substantially better protection.

I also have the KLIM D3O version that I modified to fit the jacket. The KLIM D3O version is substantially thicker (about 2x) and noticeably adds bulk, weight and stiffness to the jacket. I may end up using the KLIM D3O - it's a level of protection versus comfort decision. I will be trying both versions over the next few months.

Because I apparently cannot resist a good sale or closeout, I have too many motorcycle jackets. 1a & b) 2010 vintage Revit Cayenne Pro, and somewhat later Revit Everest; 3) Icon Leather Accelerant; 4) Alpinestars mesh, and 5) Roland Sands Leather. The Revit's and Icon came with cheap, worthless pieces of foam for "back protection," while the Alpinestars and Roland Sands came with none. The Alpinestars didn't even have a pocket to accept upgraded, "real" back protection.

I added the recommended SAS-TEC upgrades to both Revit jackets. I believe SAS-TEC provides the best possible protection. I also upgraded the Accelerant with this same SAS-TEC, although it had to be cut to fit with a box cutter.

SAS-TEC could be cut it fit the Roland Sands but since the pocket isn't designed to accept such thick armor, the SAS-TEC would distort the shape of this good looking, on-or-off the bike, jacket.

I purchased the Icon D30 Back Protector for the Roland Sands. With careful box cutter trimming, it fits perfectly. As other reviewers have noted, this is light armor, which is needed if the Roland Sands is to maintain it's trim fit. I don't know if it is superior to the Forcefield armor that is designed to fit the Roland Sands. The fact that it is $10 less than theForcefield is not the reason I chose it. Rather, I believe it is as good as the forcefield armor, and appears to be even lighter and more flexible. I think the Icon D30 Back Protector would be a good upgrade for any trim fitting leather jacket in which improved protection is desired, without harming comfort or fit. It's not track quality armor, or even good sport riding armor. If at all possible, I'd go with a Level 2 back protector for those uses. However, it is far better than no back armor, or than the cheap piece of foam that came with the Accelerant. If the jacket has no pocket for a back protector, a good seamstress can sew the D30 Back Insert into the liner.

Personally, I believe in doing whatever is necessary to avoid hitting the ground without back protection. This piece of armor fills the gap between no armor (or a piece of foam) and really substantial, Level 2 Back Protection.

I bought a whole set of these pads for a leather jacket.
They are not bulky, they fit perfectly (I measured…twice), and I hope I never have to test them! Whatever pads you choose, may you never have to use them either!

I bought this as back protection for my Roland Sands Design Ronin jacket. It was slightly too big for the back pocket, so I needed to trim it down to size.

The D30 material is lighter, breathes easier, and is less rigid than the stock armor that RSD sells.

Haven't been in an accident with it, so I can't speak to that aspect, but so far, so good.

I bought the women's size as an upgrade to the foam back pad in my girlfriend's Icon Contra Speed Queen jacket. She wears a Medium.

It definitely fits in the provided pocket, but it is about 3 inches too short top to bottom. Unfortunately, this leaves a large unprotected area approximately down to between her shoulder blades.

We have decided to use both pads at once for now and to hope we never have to test it in a crash.

I have attached a picture with the D3O back pad over top of the foam pad inside the jacket. The foam pad is placed where it would be if it was inside the pocket in the jacket.

Dropped directly into my Icon Overlord jacket. I've also used it in my Rev'It touring jacket, and it also fits in the back of my Rev'It one piece track leathers.

Inexpensive, thin, and protective. What else can you ask for?

Replaced the expanded foam pad that came in an Olympia mesh jacket. Seems to fit in just fine. Being thinner than the original, it also loosens up the jacket a bit for me, which is good since it was a tad on the tight side. Heavier than the original, but not even noticeable to me when wearing.

D3O at a great price. Fits well and well designed.
