This is the "Bring it!" fashion combo. It has a dull orange double-sleeve style long sleeve shirt with mottled gray under-sleeves. The design is a nice, big shot of CG running forward Sonic with yellow 'lightening bolt' speed trails behind him, and a background of black squares & rectangles. The slogan 'bring it' is in the upper corner, while the modern logo is in the bottom corner.
Notice that the hat that comes with this one is VERY similar to (but not the same as!) the above hat, from the first fashion combo. This hat, while beanie-styled has thicker & less dark blue stripes, though the logo is in the same position. This is a 2016 item.

Here's a "Fashion Combo" for 2015 (though it appears in 2016 also) It's a long sleeve double sleeve look shirt with beanie cap combo set. The shirt is dark navy blue with brighter blue long undersleeves. It has Sonic, Tails & Knuckles in CG, with "Game on!" written in blue below them. A similar tee was made as well, so this isn't too surprising to see. It is likely a Bio World item, as seen by the partial paper tag there (under the sleeve) The hat is pretty ordinary looking, just blue/dark blue stripe with the modern logo near the bottom. Items like this are usually plastic clipped together in the store, or the hat will be mini-tied to the shirt to prevent theft. Where is this sold?

The hooded shirt trend continues in 2015 with this green double-sleeve shirt. It has gray long under-sleeves & 2 blue stripe 'short' sleeves. That blue thing at the top is a hood, but it is made of t-shirt material, so how useful would it be against wind or cold? The design is nice though, with jumping-twist modern Sonic large in color, then, a blue line art of the same pose but larger, to create a background.

The result, with the word "Sonic" spelled out at the bottom, is a stylish & more unique looking design. Do you know where this is sold?
