Boxer Brief in Organic Cotton Rib - Sand provides full coverage and a balanced, supportive silhouette. It’s designed to feel comfortable during long wear, daily movement, and warm climates. The organic cotton is gentle on sensitive skin and helps regulate temperature, reducing irritation and maintaining softness over time.

So comfy.

Ordered one Trunk and one Boxer, both in size S. Instead, I only received the Trunk in a size M, and the Boxer was completely missing. I contacted customer service twice, once via email and once through their website contact form, and waited a full week with zero response. Just complete silence. I’m extremely disappointed, as this was my second order and I was planning on buying more because I liked the product. But given this terrible service, it will be my last. Never again!

I wanted just to feel a calm grounded kinda hotness when all I’m wearing is my jocks.. not the in your face synthetic sexy that most brands shove in my face. I’ve got the xl men’s brief. Snug but not tight, soft but not slinky. Comfy but not frumpy. Balanced.

Comfortable, good look, nice material.

The only issue is the legs aren’t as long as they look in the photo

Very happy with this product, great option for low-tox underwear because of their certifications and they are unbelievably comfy. They do ride up a little (boxer briefs) But not enough to make them not worth it. Very happy.

My new favorite briefs! They feel like a cozy sock. The waist doesn’t gather either. I love them!! Oh and they look great on!

Perfect 👌 feel and fit

I love them! They are true to size, so I’m a 32” waist and bought the M. Also, I like the fact that the branding is small and not covering the entire waistband. Definitely will be buying more.
