I went shopping to my local REI looking for new pants and settled for the REI Pulanski Pants
They are reasonably priced, very comfy, made of organic cotton and they have a side hip pocket …
… that is just the right size for a 7 inch tablet.
Ideally the pocket would be just a bit deeper and would be positioned just a bit higher in the leg, but initial tests are very positive: the tablet is readily available and it does not interfere with walking, sitting or driving. I’ll spend some more time with it this week at work and will report back.
Try this with a 10 inch tablet 🙂
Disclaimer – No actual 7 inch tablets were harmed (or used) for the photos.
