Low Rider
Thank you for the explanation of your condition. Wow! I can see how important it is to avoid back pockets.
Removing the rear pockets should still be an option.
Is a front pocket a must, or could a box mounted on the bike be used instead?
Perhaps a local seamstress could make hidden pockets on the front or sides of your jerseys.
I am just looking for alternatives to getting Primal to offer more recumbent jerseys. I doubt the market is large enough to be available in all sizes of both sexes.

With the handle of Low Rider, I assume you are a bent rider too. Is your bike a two or three-wheeler?
How do you manage your water? I was just wondering if you would be interested in the way I use magnetics to attach my water hose. Perhaps we could meet this year and talk recumbents.
