"The BN3TH Pro Ultra Boxer Brief 8" has exceptional comfort and support. The pouch technology provides separation and breathability without any restriction. I would recommend. BN3TH if you’re listening, I’ll echo the other review. More colours please!"
"I am so happy with the Pro Ultra Collection that I have purchased 3 pairs. I find they are snug but not tight, and I will gradually purchase more, as I find them comfortable for everyday wear."
"By far my favourite Bn3ths. Super comfortable and don’t ride up at all like some of the others do. Would like to see some more colours with the 8” length."
