Pack a little island night underneath.

Island Night Kit brings after-dark island symbols and vacation energy into your first layer for hotel nights, summer trips, late plans, and the kind of print that gets noticed up close. Classic Soft MicroModal™ keeps the horizontal-fly brief smooth, light, and easy against skin.

• 3x Softer Than Cotton
Premium MicroModal™ feels like a second skin from the first wear.

• Clean & Simple
A traditional brief cut that lets ultra-soft fabric do the work.

• Everyday Secure Fit
Supportive, easy-wearing shape for daily movement.

• Limited Print: Island Night Kit
Part of Coastal Joy Prints — a sea-inspired story built around color, memory, and the feeling of being closer to the coast.

• Horizontal Fly Design
Clean classic-brief construction with quick, natural access and a smooth front.

• Cloud-Touch™ Waistband
Premium jacquard logo waistband with a velvet-soft brushed liner for a secure feel without digging or rolling.

• Contour-Cut Leg Openings
Clean lines sit flat against the thigh and stay smooth under pants.

• Frictionless Construction
Flatlock seams and a tagless label help reduce scratching, rubbing, and daily irritation.

• 4-Way Micro-Stretch
Moves with your body while keeping its shape through everyday wear.

• Ergonomic Rear Fit
A contoured back panel helps reduce bunching and wedgies.

• Precision Reactive Print
Animal patterns stay vivid and sharp with durable reactive dyes that bond to fiber and will not crack or peel.

Island Night Kit

Island Night Kit is inspired by island night markets, tropical details, surfboards, drinks, and the relaxed after-dark side of vacation.

Surfboards, tropical details, drinks, and vacation objects pop across a black base like souvenirs from an island night market. It brings daytime beach fun into a cooler, more rhythmic after-dark mood.

It feels like the next chapter after a day by the water: sunlight fades, music and lights appear, and the night breeze starts to move. Beyond the bright beach mood, this print keeps the warmth, rhythm, and memory of an island evening.

Customer Reviews

Overall rating: 4.7 / 5 from 7 reviews.

As always I love the fit, feel, & support of these briefs. However the print left a little to be desired. Because the scale is so large you risk not seeing the sailboat at all. The only place that the sailboat showed up on my entire pair of briefs is on the inside of the fly. So kinda sad that when I'm wearing them the briefs just look blue with white lines.
