Interesting video... Since he's not using the pack as intended, I agree he should have just purchased a much cheaper backpack not designed for photography.I was looking at reviews for the Think Tank 26L and came across this guy... Did he really just take an (almost) $300 pack and slice it open and remove the foam so he could turn it into a standard $100 day pack???
But it does cause me to ask the question, does the 26L not compress at ALL, is it as stiff and impossible as he makes it sound? I feel like I could generally compress foam with the compression straps if I actually wanted to. IDK.
26L "Pack Hack"
One of the nice features of this pack is being able to keep it on your hips and spin it on your body to access the gear without having to put anything on the ground. This is great in wet, snowy and muddy locations. I avoided a lot of penguin poop smears when changing lenses on South Georgia Island with this feature, but I suppose it would have added to the patina of the pack if I hadn't.
When I fly, the pack is loaded with my camera bodies, long and wide angle lenses, batteries and binoculars, all of which are the thickness of the pad anyway. I fold and click the waist straps over the back of the pack when boarding and just carry it with the shoulder strap on one side. Even flying on notoriously strict airlines, I've never had anyone raise concerns about the pack size (thankfully they never weight it!). I don't overstuff the back with extra clothing as I just wear layers on the plane and shed them depending upon comfort. I do have a thin laptop inside. I've honestly never had difficulty fitting it under the seat in front of me and I can usually still get a foot on either side of it once stowed.
