Probably them ultra skinny pants which restrict blood flow, they usually have smaller pockets than the standard straight fit jeans
Or, ya know, pants that look good on them. I don't wear skinny jeans, but I'm a thin person and I've never looked good in loose fitting jeans. Slim-fitting jeans are my go-to, and I don't plan on buying new pants that I like less just because no Android manufacturer out there wants to make a reasonably-sized device. I'm still baffled by this new direction that the Nexus line is taking. I just can't see who can look at a 6" phone and find it practical. Maybe I'll take that back in a year, but I found the LG G3 to be the absolute largest I'll ever go with a phone (and even then, it was a little uncomfortable) and I don't see that changing anytime soon.
