Just used this weekend, for the first time, on a full day fat bike adventure. Really great. Not as massive as some others i've seen, but goes from "large saddle bag" to "huge saddle bag", which is cool because it's not always huge. The front of the bag (at the post), is pretty wide. If you are a rider (like me), who's thighs touch the seat post a bit, it will touch the bag instead. I was worried, but it didn't bother me over 12 hours in the saddle this weekend. Hope it's similar on my road and gravel bikes. We'll find out.

Great product
I've been using this saddle bag for a few months now, and it's been wonderful. The two BOA dials are such a good design feature. The bag feels tight against my saddle and I never have to worry about it flailing around or falling off even when fully loaded.

I use a traditional steel frame road bike and this bag grazes the back of my thighs while pedalling. I can't seem to get the seat post BOA tight enough to keep from wobbling either, and fully tight feels like the lines and BOA are under stress. For me, just a little more space, like an inch longer, would've made this thing perfect for my lunch/repair kit for work commutes, but as it stands, a bit small volume-wise. Overall, pretty okay.
