Sizing Information

We measured a sampling of these jeans of different waist sizes and lengths and find the waist band measures out to the stated size. Most jeans are “vanity” sized which mean they’ll measure about 2” larger than the stated size in the waist. To pick a size, you’ll want to measure your waist (use our instructions below) and choose the size which corresponds to waist measurement. Alternately you can measure the waist band of your favorite slacks, chinos or jeans to figure out your measured waist size. Because your favorite jeans are likely vanity sized by about 2”, you’ll wind up choosing a size in this pant that one size larger than your jean size.
