Product Review; "Made in USA clothing is something everyone has to try - the seams don't come unthreaded by the 5th time you wash it, The fabric is generally thicker and made from better materials and it's just dependable - I'm never surprised by some manufactutring fault or defect in production. This Long Sleeve Shirt is less than $20 but performs to the quality standards that other companies charge $45 for. This is a nice lounging or school shirt - no logos or patterns, just a simple well fitting 100% Cotton Long-Sleeve / Light Sweater." -MadeInUSAReview
