I recently had a chance to try out a couple of backpacks of higher price (a slim and a regular sized one) and realized from the experience how light and great of a value the UPD Pinch is.
Although I cannot attest to any of the recent budget backpacks that have emerged, I can praise just how incredible the UPD Pinch is. I love how versatile and customizable this backpack is. It's somewhat of a combination of the Shift (two outer mesh pockets) and the Rebel (bottom storage), but it's a whole lot cheaper.
The one slight annoyance I have had with it is the lack of an internal frame; the outer pockets "pinch" into the backpack. The discs can get mushed in and sloppy depending on # of discs but it's a minor thing esp. at the price point.
For the longest time, I've tried to figure out an effective way to put in support. PVC pipe was too heavy and bulky. I only recently found a cardboard box that would fit in. Not sure how it'll hold up but for how cheap and easy it was to make, it is fantastic.
For the record, I have the version 1 Pinch. I know v2 has raised up the putter pocket, widened the opening for easier access to the bottom storage, and other things, but I think the pinch effect is still there? Frugal me couldn't get myself to upgrade even at the great holiday price it is at now. However, this simple add-in has me very satisfied.
All in all, after trying out a couple other bags, it has made me appreciate the UPD Pinch even more. It's light, good material, can hold a decent amount of discs along with enough extras, very customizable and the price point is just incredible.
