I have the alpkit seat pack too, but have mixed feelings about it. Have used it extensively, and sometimes it's great; other times it swings around a lot/needs constant re-tightening. I think my seat post height + saddle angle might be hindering my ability to put it on properly. Also, it's a huge pain to get on at all, and then you have to take it off if you want to remove anything. Or am I just doing it wrong?
Do you have a bigger one maybe? I've had non of the issues you describe. Pack it as full as you can and tighten everything, pull the side/top straps through the saddle rails
I've got the 13L one, and sometimes fill it to absolute capacity. Looking at your photo, I might have been putting it on wrong...I've never put the top straps through the saddle rails.
