Is the 6-inch inseam long enough to stop chafing?

Six inches covers most of the upper thigh, which is enough for many men to avoid rubbing under shorts or jeans. If you are tall or have thick thighs, a 9-inch boxer brief may suit you better.

How does the Flex Trunk fit compared with other American Eagle underwear?

It fits true to size for most buyers, similar to AE's other flex styles. Big and tall sizes run on a separate scale, so check the size chart before ordering.

Is polyester and spandex good for everyday wear?

Yes for stretch and durability, but the fabric traps heat more than cotton or modal. It dries fast, which helps for travel and gym days.

This trunk is a pull-on style without a functional fly. That is common for stretch trunks at this length.

When is the best time to buy?

American Eagle runs frequent promotions and multipack deals, and clearance tends to hit at season changes. Buying a pack rather than single pairs usually gives the lowest cost per pair.

Our take on the American Eagle Men's 6" Flex Trunk

The American Eagle Men's 6" Flex Trunk is a stretch boxer brief made from a polyester and spandex blend, sold in black and offered in regular, big and tall sizes. The 6-inch inseam sits between short trunks and longer boxer briefs, so it stays put without riding up much. It is a basic everyday underwear pick rather than a technical or performance piece.
