I know this is designed for the Fisherman in mind but i bought this product primarily to compliment my new hobby of nature watching. Two side pockets carries my flask and water. A front pocket carries my field book, first aid kit, map etc. whilst the main compartment has plenty of room for my waterproofs, field scope, pack lunch and just about anything else i want to put in there. Totally waterproof lined interiors. when packed up ready for walking the rucksack looks and feels like a framed rucksack, comfortable and airy to the back and actually reduces build up of sweat down the back by letting air circulate around your body. The seat is comfortable enough, you can have it in the stool position, which i use when out walking and with the back rest up which comes in handy for those longer periods of sitting. weighs in at about 6lbs which causes me no probs, i usually carry about 20lb on a normal day out anyway. all in all a very good buy, i'm really pleased with it and it beats sitting/kneeling in the wet grass on an early morning outing. There are cheaper alternatives and you can tell they are cheaper. Fully recommended
