Comment/question from a non-recumbenteer: In ye olden dayes, I'm guessing before the 60s or 70s (but even a little bit after this, cos I remember my mum buying me similar in about 1987 – but it was only from M&S!), cycling jerseys had pockets on the front. Are they or would they be if still made, any good for recumbent riding?
Which in turn makes me think of a kurta – loose fitting cotton shirt, common in South Asia, with pockets at the sides. IME great for hot weather riding (on knuprites) if not in too great a hurry. The pockets are on the sides and fairly deep, so should be accessible to recumbentists and I think probably sufficiently vertical and deep for things not to fall out. Possible airbrake effect though...
