on an
epic bike ride next week, so he asked me if I could use my "magical construction powers" and conjure up a solar pocket for his
Hydrapak. As in he wanted to be able to use his solar charger to charge his cell phone while riding, so of course I told him I could.
After some designing in my head, construction and application, he has an awesome solar pocket that he thinks might make him the envy of (at least some) of the other riders. He also thinks it should become regular design feature of all sorts of packs in general.
