Chicago-based Loop Attachment is back on our radar again, now that the company has released its unique Straitjacket Case for iPhone 6 ($US34.95).

While nothing has changed in this TUAW 3.5-star rated iPhone case in terms of design, materials, or just plain usefulness, it's now available in the larger iPhone 6 size in some eyecatching colors - blue/black, red/black, white/gray, white/mint, and black/gray.

I'm not currently using the Straitjacket since I have an iPhone 6 Plus, but I can vouch for just how useful the case is in providing protection for your iPhone while also giving you a place to slide an ID and credit card or two. It has a great grippy feel and really adds a splash of color to your favorite iPhone.
