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.

The Grinta Roll Top Bag is an excellent bike packing addition for packing lite and traveling fast and far … the wire purge valve, easy roll top, waterproof design and secure attachment to the bike (the bag does NOT move), the Boa dials to get the fit right and tight. The only suggestion … the ingress of grit (wet weather and silica based gravel) can make the bottom boa difficult to “un lock”.
