Hey all.
I have a new setup on my winter fixed gear.
I have a bit of a fixed townie.
I'm totally new to the upright seating at least as an adult.
The problem is that my rain jacket tail catches quite firmly under the tail of my saddle often when dismounting.
This has nearly taken me down a few times.
The saddle is a Berthoud Aspin.
The rain jacket is quite large because I fall between sizes.
I rather like the extra size to enable a lot of bulky layering during winter, but this means a long tail.
Just wondering if some townie riders here have run into this problem.
If so, how did you deal with it?
I'm trying to avoid asking my wife to shoot pictures and video, but that might help.
Anyway, thanks in advance for your suggestions.

Try tucking the tail under your bum when you first sit down on the saddle.

Does the bottom hem of the jacket have a drawstring to seal it up? Just use that to snug it against you before getting on the bicycle. If no drawstring you might look at the jacket's bottom hem and see if you could cut a small hole(s) in it and 'fish' cord/string through it, or maybe some elastic, to achieve the same results.

Well damn, you can teach an old dog new tricks.
I have not touched that drawstring for many years.
Thank you for the simple fix.

My first thought is to take an appropriate sized "bite" out of the tail. If it were me, I would then seal the edge with heat or glue.
Good luck, and don't take your helmet off until you are clearly off the bike.

I have a pair of shorts that tend to do that too. I've learned to be Very Careful when dismounting when I'm wearing 'em.

They have a drawstring that I'm careful about tensioning, yet it still happens. Hence the caution.

I don't bother with shorts when I'm on my trainer though so it'll be a few more weeks before I have to remind myself about this issue....
