If your vehicle is not equipped with wiring for towing a trailer, CURT custom wiring is the ideal solution. A custom wiring harness -- also called a T-connector -- is a simple, plug-and-play electrical device that plugs into your automotive electric system and provides a standard, universal trailer wiring connection. This is done using two or more vehicle-specific, OEM-compatible connectors to plug into the taillight assembly, eliminating the need for cutting, splicing and soldering during installation. Custom wiring harnesses are made vehicle-specific, and while they are not available for all vehicles, they do offer one of the fastest, easiest and most secure ways to wire a vehicle for towing. This particular plug-in harness provides a 4-way flat connector socket and is designed to be a custom wiring harness to fit certain years of the Kia Optima sedan (to verify your vehicle compatibility, see application info). It comes with all necessary wiring components to establish a reliable trailer wiring connection, as well as a dust cover to keep the connector clean when not in use. You have a picture in mind of your next destination -- maybe it's the boat landing at your favorite fishing spot, maybe it's a campsite that overlooks one of nature's masterpieces, or maybe it's the next big jobsite. However, turning that picture into a reality takes more than just daydreaming. It takes a solid connection and the right amount of power. CURT custom wiring is made with some of the most sophisticated technology in the industry and is designed to install with ease, giving you a long-lasting electrical connection for your towing hitch setup.

THE shirt for broad shoulders, bigger chest, and a bigger midsection…
I have the body of a middle aged ex-athlete. Broad shoulders, muscular arms, larger chest, and a larger waist. The cut of most shirts don’t do well with this body type. In order for a typical shirt to look good with this body type requires you to get a size large enough to fit the larger midsection which then makes the fit on the upper body too loose. The designers of this shirt clearly know my body type. I can still look athletic with a good, close fit on the upper body while having a little extra room for the waist. It’s a great fit. The material is a nice polyester. Good drape and doesn’t wrinkle easily. I own 4 of these and will be buying more.

Not bad really
Size: Large, Color: Light Grey Heather
I purchased a size Large and it's just a smidge loose but it's nothing that is really noticeable or uncomfy. I'm about 180lbs at 5'9 with somewhat of a beer belly but not a huge one lol. If you're body is about the same as mine and if you want a more fitted feel them go with a medium. So overall it's very comfortable it's my 3rd Amazon brand type of garment or clothing that ive purchased so far. Still too early to tell just how durable it is but I'll be sure to update that eventually. I use it for work (nothing heavy white collar work) and during the warm seasons I absolutely loath regular cotton style shirts. I'm not a fan of the summer weather so I tend to buy clothing that is more suitable for warm temps. This is 100% polyester and it's breathable as heck. That's what I like most about it. The overall texture and feel is somewhat "rough" but soft at the same time (if that makes any sense) but it's nothing that you'll be self conscious about. So don't let that scare you away. It's comfy and inexpensive and I recommend.

Great quality, seems to run just a little big
This is an excellent quality shirt. While I haven't put the "quick-dry" feature to the test, it definitely feels like it would dry quickly if wet. It has a little bit of weight to it but not so much that it feels heavy, just that you're well aware you're wearing it. I picked up a large and I'm about 5'9 and 175lbs (and 14 neck) - and I feel like I'm swimming in this thing (it's a bit on the bigger side). I'm definitely going to order more, probably several, but will likely drop down to a Medium and see how big a difference it makes. Hopefully it fits better without being too small. Overall, great quality and value - highly recommended (whether for golf, work, or just casual outings).
