Iam using a travel back pack of wildcraft worth rs.6500. Its very good.i love it.I use to go for trecking and long rides using this bag.
It has an adjustable strap which is ideal for bike riders.so I always recommend wildcraft bag.iam using the model gangotri.its green color.actually I brought it because I have seen that bag in many movies the hero is using this bag as in vikramadhithyan and abcd.since its so stylish.
