Here’s a product that’s designed to sort the men from the boys,  the carnivores from the herbivores:  2 kilo jeans. Since they went on sale in October 2010, demand for these extra heavy, extra thick denim trousers has been high, with popular sizes now available on pre-order only, according to Nikkei Trendy.

Typical jeans come in at around 11 to 15 ounces, but recently there’ve been a few new styles made that weigh over 20 ounces. Eight-G, the company behind these new jeans, have taken that micro-trend and run with it, manufacturing a pair of jeans that weigh in at a hefty 28 ounces. The jeans are custom made at Eight-G’s, Jeans Center Sakai store in Ishikawa City, Chiba, with sewing machines that were specially altered to be able to bite through the exceptionally thick denim fabric. All that effort means that this new product comes with an equally hefty price tag of ¥33,000.

The jeans have been featured in men’s lifestyle magazines Lightning and Daytona Bros, both of which target an audience who hanker after an outdoorsy American lifestyle. The positive publicity has evidently worked and they’ve proved a hit with bikers and denim lovers in their 30s and 40s who are keen to take up the challenge of wearing these heavy-duty jeans.
