I had bought this combo from amazon @2.6k . Later I came to know that this can be bought directly from here.
Pros--
1) Durable & Lightweight material
2) Padding & Back support
3) Ergonomical Design
4) Free Daypack & Raincover.
5) A few loops to attach my stuff with carabiners.
6) Adjustable shoulder strap
7) Bottom Opening
Cons--
1) Where am I supposed to put my water bottles (1000ml) in the bag ?
Overall a VFM product.
P.S. Why can't I find any colonel series rucksack of Sea-Green colour ???
