First & foremost, The way 'The Humbl Co' connects with the present day youth with quotes such as 'I Am Humbl' and 'Always Real' does make sense.
Secondly, 'The Humbl Co' isn't only trendy but also very much affordable. Branded T-Shirt for anywhere around Rs 500 is a steal any day and you can't expect anything better than it at that price point.
Thirdly, Simplicity is one of those traits of Mahesh Babu which made him a favourite of millions of people. Even the 'The Humbl Co' Apparel are as simple as it can be with decent looking colors, a nice quote and few stripes.
