I am sharing my personal experience with the purchasing of buffalo jeans and t-shirts from big bazaar at GIP Mall noida.
I purchased a Jean and t-shirts 1 year back and I still wearing it in regular basis. so you can imagine its durability.
This might look costly but as compared to other products this is nice and comfortable in every body type. if I am talking about customer service, yes its good. if you want to replace your stuff, you can replace it any buffalo store. they use to update you with there new collections. staff is also good at their stores.
