The classic you love, now made to tuck. This SmoothTuck Tucking Boy Short features our high-performance 4-way stretch fabric for a more comfortable, secure, and flexible tuck—delivering the smooth, confident silhouette you’ve been looking for.

With the same trusted mid-rise, cheeky fit you love, this style is reengineered in our new SmoothTuck line for (you guessed it) smoother support and an even better fit. The upgraded compression fabric provides snug, secure hold while maintaining breathability, moisture-wicking, and quick-drying performance to keep you fresh and comfortable all day long. A wider, more accommodating crotch ensures a better fit across body types—so you can move freely, confidently, and comfortably, wherever the day takes you.

Fits true to size, we recommend the size you'd wear in non-tucking underwear.

Violet ★★★★★

The 4-way stretch fabric hugs without squeezing, so I can wear it all day and forget it’s there. Secure but never restrictive, and the smooth finish keeps everything in place under jeans or dress pants. Finally a tuck that doesn’t feel like a constant adjustment.

Scarlett E. ★★★★★

The rainbow pattern looks even better in person, and the 4-way stretch fabric moves with me all day without any pinching or bunching. I wore it to work and forgot I had it on, which is the highest praise I can give.

Scarlett Q. ★★★★★

The four-way stretch fabric is a game changer—it moves with me through a full workday without ever needing a readjustment. I’ve tried other tucking options that pinched or slid, but this one stays put and feels genuinely secure. It’s the first pair I’ve worn that I actually forget I have on.
