"The Classic Icon Trunks with the fly have been my go to for comfort, style, and quality. Because of this, it was not all that difficult to justify the premium price. However I recently reordered and I will say they are no longer what they were. The new material is thinner, and while still comfortable, it does not wear well. After a couple of months, under reasonable wear and care, they are already falling apart at the waist band. This is disapointing as I can no longer justify the price, and unless there’s another evolution to address the quality shift, it will be time to buy from a another brand."

Reviews
Comfortable Underwear
"Smooth, cool underwear. Waist band is just right."
Solid underwear
"I like the shorter length of the trunk from Bn3th. The fabric is soft, lightweight and it is like you aren't wearing anything. I am not sure if I notice the fly but good to have the option. A bit pricey but they last and the waist band does not stretch out like other brands."
Great Feel and Fit
"The fabric feels great on the skin and the pouch certainly helps keep everything in place and comfortable all day."
not quite the same as the first time around
"I bought a dozen or so pairs 6-7 years ago…. this batch has a tighter waist band and don’t seem quite as soft…but the feel is ok. I washed a couple of pairs and the first time I wore them I was on the “john” and spotted a small…run…hole ( picture attached )"
