Saddle pack without velcro round seatpost

Can anyone recommend me a good saddle pack that does not have a velcro band around the seatpost and that mounts as far back on the saddle as sensible? I'd like it to be large enough to carry a couple of spare tubes, plus tyre levers and a multi-tool, tie wraps, emergency cash etc. Don't need space for phone, co2 or stuff like that.

I'm short but have longish thigh bones and as a result have my seat pushed a long way back (and yes I have had a bike fit), this means that my thighs catch on any velcro around the seatpost and also against the front sides of my current Topeak bag.

I've seen ones by Scicon which seem to be what I'm looking for but a number of the reviews report issues with the clamp being weak and rattling.

My saddle is a Selle italia C2 Gel Flow with conventional rails.
