Interesting. Very similar to the Osprey Daylite Pack. The Black Hole version is a lightweight packable and the Terravia is probably much more comfortable. The specs describe a bag that is more like 21 liters at most: Gear Capacity: 24 L (1,465 cu in) Dimensions: 16" x 10" x 8" Weight: 14.8 oz (420 g) More on reddit.com

I have the previous version that I bought in 2016. I’ve been using it every day and it’s still going. Groceries, tablet, travel, it all fits. I’ve taken it as a packable day pack on several international trips. I found mine reasonably comfortable but others have not. I think it depends on back shape and shoulders. You have to pack it properly for it to be comfortable More on reddit.com

I've been using the Black Hole 32L for the last 1.5 years (since the refresh came out in August 2023) and although I do really like it and continue to use it, there are definitely a few annoying things about it. I don't know if they're the same as for the 25L but I'm curious if anyone else has the same qualms with it: The position of the top handle is really weird... It makes it so that you can't really hang the bag on the back of a bathroom stall or whatever, since the rigidity of the bag completely falls apart if you try to open it while holding from the handle. If you pick up the bag from the handle while it's unzipped, all the weight transfers to the bottom of the zippers on either side, and it feels like you're going to rip the bag in half. The side pockets suck. Every non-disposable bottle can just fall right out of it. There's no way to cinch down the pocket. My biggest issue by far - the shoulder straps and back panel are just not comfortable to me at all. Maybe it's better with the 25L because there's less weight when you've got it fully loaded, but for the 32, I feel like they should have used thicker/stronger shoulder straps. For context I'm 6'3 200 lbs and used to carrying bags. The 32L just doesn't handle the weight comfortably for me. I made a video about this yesterday actually - I'm not a youtuber, I just had to share my opinions on it somewhere since this bag is so frequently brought up here in my favorite sub. Hope it helps someone make a more informed purchase. More on reddit.com

I agree that the inner pocket is mostly useless. However, I usually store some small items (non bulky) like cables in it. I LOVE the front outer pocket though, it really holds quite a lot like my liquids bag and other misc items, even flip flops. The top one I use for snacks and phone charger. More on reddit.com
