I originally bought the 14L thinking it would be big enough, but returned it after trying to fit my gear in it. My Canon R5 with RF 70-200 2.8, 50 1.8 RF, 85 1.8 EF, and 40 EF with RF adapter all fit in the 14L but it was snug, making it kinda difficult to get the camera in and out. I like it to be quick and easy, and the 16L gave a decent amount more room, and flexibility. I like that the 16L has a waist belt, which could come in handy when you need your camera, but don't want to put the bag on ground, you can take straps off shoulders and rotate the bag to front of body and access rear camera zip area. I rarely carry a tripod, so I use that area of the bag to carry a second water bottle, a 40 once Klean Kanteen fits in there snuggly. The 40 once also fits in the ... MoreI originally bought the 14L thinking it would be big enough, but returned it after trying to fit my gear in it.

I like that the 16L has a waist belt, which could come in handy when you need your camera, but don't want to put the bag on ground, you can take straps off shoulders and rotate the bag to front of body and access rear camera zip area. I rarely carry a tripod, so I use that area of the bag to carry a second water bottle, a 40 once Klean Kanteen fits in there snuggly. The 40 once also fits in the mesh water bottle slot, but it's a very tight fit. Sides slots are about same size on 14L and 16L. The top section is not huge, but holds some lunch, snacks, a rain coat and extra shirt easily. I wish I could lower the base of the top section better to carry more non-camera stuff. I wish the velcro inserts were a little more adaptable, but they work pretty well for my needs. I haven't taken my MacBook with me yet, but glad you can. I tried putting my 13 MacBook pro in the 14L, it fit, but was quite tight when the bag was filled with my regular gear, and wouldn't fit with a protective sleeve over it. I use mine to take to the bike jumps, so in the front part I fit a tool roll, bike tube, small pump, phone, wallet, keys, and other small stuff. Overall, it's a pretty great bag, good for hiking or urban exploring, even comfy for short bike rides. I dig the colors and the back camera area, which I adapted some. An included rain cover would be nice for all versions. If you have a smaller Apsc or micro 4/3 set up the 10L or 14L would be good, or bigger cameras with minimal stuff to take. Otherwise the 16L is still light and small enough to not be annoying to carry around like other backpacks and camera bags have been for me.

I wanted a compact, lightweight bag for hiking with separate compartments for camera gear and food/clothes, plus side pockets for a water bottle and a tripod.I chose the 14L over the 16L to force myself to carry less in an effort to keep the weight down. The camera section was on the smaller side and was a bit tight getting things in and out if you used every available inch of space. I wondered more than once if I should have bought the 16L instead, but the heavier bag plus extra gear I would have stuffed in there would have added 2-3 pounds, and I'm glad I wasn't carrying the extra weight. I used the bag on 2 back to back day hikes, each about 6 miles with a few hundred feet of elevation gain. It was incredibly comfortable and easy to carry. I had never used a ... MoreI wanted a compact, lightweight bag for hiking with separate compartments for camera gear and food/clothes, plus side pockets for a water bottle and a tripod.I chose the 14L over the 16L to force myself to carry less in an effort to keep the weight down.

I used the bag on 2 back to back day hikes, each about 6 miles with a few hundred feet of elevation gain. It was incredibly comfortable and easy to carry. I had never used a rolltop bag before and was initially concerned about that design and the buckle latch instead of a zipper, but it was easy to work with and stayed secure when pulled tight.My pictures show some options with a Canon 5D4, 16-35 f/4, 24-105 f/4, 24-70 f/2.8, and 70-200 f/2.8, as well as with a 750mL Camelbak water bottle and Leofoto LS-284C tripod in the side pockets. The top storage compartment held a shirt, towel, baseball cap, sandwich, chips, and some other snacks.I will definitely bring this bag on my next hiking trip.

The bag holds 2 bodies and attached lenses comfortably. I'm using it with an 7 IV with a vertical grip and 100-400mm F4.5-5.6 GM. In the other half, I have an 7R V with a 24-70mm f/2.8 GM II. It's comfortable enough for short hikes. The tripod pocket is well designed; both side pockets fit 1L Nalgene bottles.The buckle and strap for the rolltop can be improved. The strap material doesn't slide as well as standard backpacking straps, and the bottom ripped out already (it's still functional). The metal hook buckle looks cool, but it doesn't work as well as a FIDLOCK or standard ITW buckle. I still like this bag because it's comfortable, protective, and looks like a regular backpack.
