Alpinestars Andean 2Dry starJacket purchased to install RSThailand Ji Tech CellChest protector. The Snap button is uneven, the NylonTape's Length is different, making is not complicated. Barely, since only the interval of Snap buttons was available, I decided to use it as it is. Sewing to Jacket was done without problem. When installing Protector, the Snap button is a bit hard and difficult to enter, but it may be partly removed during wearing (I think that it is a problem of this product because there is no problem when installing RSThailand Ji Protector to Honda's Jacket). Thanks to this product, it will be appreciated as Jacket and Protector will be more selective.
