Amazing quality and fit. I really like how this brand offers unique prints that I don't see anywhere else.

These are my go-to black swim trunks now. Simple, sharp and the 5-inch length looks much better than longer board shorts.

The onyx color is a nice super dark black. These fit true to size and feel much more high end than typical black swim trunks.

The Onyx color is sleek and easy to wear with everything. The 5-inch fit is flattering, the fabric dries quickly, and the compression liner is a major upgrade from standard mesh.

The Tulum 5-inch swim trunks have a great tailored look. I ordered the black pair and they go with everything. They’re simple, comfortable, and feel more elevated than most men’s swim trunks I’ve tried.

First, I'd like to say I appreciate that these are made with recycled materials! And they are so comfortable and well made. I ordered black as my first pair to test them out, and really like the fit and comfort level. Will be ordering some prints next. Nice to have some more stylish options in trunks that are also more eco-friendly!

I really like the gunmetal silver color accents on these with the drawstrings, and the fabric is really nice. They dry quickly, they never look wrinkled, and they are so comfortable.

Great proportions with the shorter inseam. Really nice true black color, and soft fabric. Worn them a handfull of times now and the quality is excellent.

Best fabric and fit. These swim trunks are so comfortable and well made. I wear them all the time, not just to the beach or pool because they are so comfortable.
