f.stop bags are without comparison.my manfrotto veloce iii has the velcros strap, and fits roughly between the size of those 2 bags.
perfect for my 15.6" laptop, ipad mini, 5Dii, 70-200 2.8, 24-70 2.8, 50 1.4, EX580ii, chargers and a few other odds and ends.
and best of all, opens from the back so no-one can steal your shit/things cant fall out.
There are no other bags available that are truly comfortable after a long day on you back with full camera kit + stuff.
(Tilopa BC will carry skis/board if you want it to).
The rearward opening has more merit than just theft prevention - it means you aren't resting your pack on its harness (in the dirt/wet) when you need to access gear.
Plus they function as stand alone packs without any of the padding/dividers etc.
Craig, you'll love it!
