Decent fathers day gift idea assuming your dad can carry 80L on his back. If you have spent much time looking at rock fishing in Sydney you'll know who Alex is, and this is the bag that he uses for his trips. The capacity is overkill for what I do but if you carry big bulky items (ie Alveys) or carry for multiple people/days this seems like a decent bag. I havent used it myself but Alex is no doubt doing it tough ATM given his charter business is probably not too busy.
Description below & i think he has a video of what he puts in it either on his instagram or youtube
This Backpack is a minimum size of 80+ litres. At full capacity it is approximately 100+ litres.The two large detachable side pockets are large enough to use as a practical day pack for your food, drinks, camera gear, spare clothing or whatever you need to put into a 15+ litres size pack.
The side pockets are easy to detach from the main pack with the double sided zipper and easy to zip back on again. How convenient is that! You can be at your camp site, hiking, fishing, hunting or when you at your hotel / motel, backpacker, hostel and just unzip the large side pockets and it will be practical as a day pack. I find it very useful as I do not need to have a smaller bag or pack to add as it is part of the main backpack anyway. One less bag to have!
The seven pockets allow you to have designated spots for your tools, gear, cloths, so convenient compared with those annoying packs that have far fewer compartments. No more emptying your backpack to find that small item. You will find this backpack very convenient with stacks of room.
this is a decent sized backpack for the money and decent quality,
