Custom or made to order products cannot be canceled or refunded as these products are put into production specifically for your order.  These units are custom made to your specification or created once you order. Once you place your order they start building your unit. Your warranty will guarantee you a fully functional and operational product.

Refunds & Returns

If you need to exchange your product, you may do so.  You, as the customer, are responsible for any shipping costs throughout any returns or exchange processes. 

Not all orders are available for return once they have shipped.  We order products directly from the manufacturer. Therefore, if the manufacturer will not permit us to return a product, we cannot offer you a return. This often varies on a case-by-case basis; please reach out to us if you would like specific information on your brand and/or product. 

Due to drastically increasing LTL/freight shipping costs, any outright returns will incur a 25% cancellation fee + return shipping costs. If you are replacing the product with something else, we may be able to help you cover some of the costs depending on the product.

Seller reserves the right to refuse to refund any deposit or payment, or cancel any payment due, and any owing until such time as Seller a) is in receipt of the goods b) has inspected the goods and c) in the Sellers discretion, has found the goods to be free of damage. All refunds will be provided within 5 business days once the product has been returned to the warehouse and inspected for damage.

Shipping Times

We promise to do our best to get your order to you as soon as possible.  We provide estimated shipping times on the product pages based upon what our suppliers and freight companies tell us, and those estimated shipping times may change or vary without notice (Due to supply chain issues, the steel mills behind on making metal, the manufacturers delayed because of the mills, the overwhelming demand on shipping, factory/warehouse and dock workers and so on).

Nice Fit
Color: Black, White, Light Gray, Size: 3X-Large
I picked this up looking for something simple but clean, and it delivered. The fit is comfortable, the material feels solid, and it looks good without needing much effort. It’s one of those pieces you can throw on and still look put together.

Good value, soft and comfortable
Color: Black, Army Green, Light Gray, Size: 4X-Large, Color: Black, Army Green, Light Gray, Size: 4X-Large
Initial thoughts are very positive with this 3 pack shirt set. The green is similar to an OD military green and the black and gray are standard color shades. Material is soft and sizes are true to size. The mock turtleneck isn’t too tight but may still be a little annoying to some people. I do question the amount of spandex in these shirts. Tag says 5% but these shirts are extremely stretchy and feels like a higher spandex content. It’s also a little tough to figure out which way is the front of the shirt. Visually rhe front does have a lower collar line than the back but would still be nice to have a brand tag printed in the back of the shirt for quicker identification. Overall for roughly $12 a shirt these are a good choice for everyday wear. I will update rating if these shirts fail to meet expectations after further use.

Just what I wanted.
Color: Black, Navy Blue, Wine Red, Size: 5X-Large
These may have just become my standard shirt to wear. Feels good whether tucked or out. Drapes well and fits well. So far, I can see it adjust to the different undershirt I may wear. Will probably order another set in other colors and a back up set of the basics because they will get worn a lot.
