Goodwear: Well made casual clothing.
I’ve read about Goodwear and supposedly they use average quality cotton, but make their garments quite thick and well crafted. For these reasons this brand is one often favored by the high-end work wear community in the US, UK, Japan, and others…
Also there is talk of possibly considering doing a super-heavyweight Supima t-shirt which would push the envelope indeed.
Here is a description by Aero leathers:
"Goodwear's trademark heavyweight T is tubular, two-needled, and built to last. Made In USA, these T-shirts are American made at every step along the supply chain, from US-grown cotton to domestic ginning and spinning, to assembly with American truckers transporting their raw materials and finished products
We've conducted our own tests here at Aero, our Goodwear test shirts have had on average 40 washes each, there is no loss of shape, stretching round the neck, Yes Goodwear DO make the World's Best T-Shirts!!!
Shrink can range from 3-10% depending on washing and drying time and heat (aeroleather)."
