## Questions & Answers

**Q: Will these work in alpinestars t faster air jacket?  i don’t see any dedicated pockets for chest pads?**
A: Yes they do...the zipper on the bottom  of your jacket leads to 2 little velcro openings. 1 for each chest pad. You may have to almost pull the jacket through the zipper slot to find them, but they are there.

**Q: Would these work with alpinestars t-gp plus r air jacket ? i'm having a hard time accessing the stock foam chest pads to replace with these new ones**
A: For anyone with a mesh Alpinestars jacket with the foam chest inserts: Look below the 3/4 zip strip of zipper material (bottom, beneath back protector and inside of jacket) and you should find an additional hidden zipper that extends across the lower back of the jacket. Open the zipper and reach to the lower pocket where the foam chest insert is located and open the Velcro fastening to remove and replace the chest insert. This was the exact procedure for the Alpinestars Amok Drystar jacket and should be similar, if not identical to most of their mesh jackets.

**Q: What is the CE rating? 1-2-3?**
A: CE level 2.  Certified to prEN 1621-3:2013

**Q: I have the alpinestars t-gp r air v2 jacket in large, do i buy the medium/xl chest pads?**
A: Yes medium-XL fits all jackets in that range

Fits nice into the RV2 Mesh Jacket., The weight added to the jacket is very less than I expected at first.On placing these small things I feel more confident and the jacket even shows up nice structure on wearing.I wish amazon should insist the sellers to display the pictures of product in package., so that customers could be more confident while purchasing.
