These are quite possibly, NO they are the best underwear I have ever worn. the feel, the long term lifespan is fantastic, I could not be more happy, since going from Polyester/Bamboo {small amount of bamboo} of the popular Step Ones selling that I used to have. Go get these.

So soft and comfortable!
A few years ago, a friend told me he got merino wool shirts and underwear for his traveling lifestyle, and I decided to try them out. I ordered four different brands of merino boxer briefs from some of the main brands I could find, and these ones from Merino Protect were by far the best. The fit is perfect, due to the stretch in the material. I'd say they are true to size. The length is also perfect -- longer down the legs than some of the others (some of the others started to feel like loose boxers after a few wears, without the tight grip). They hold up well in the wash (cold water). The difference in odor control is amazing -- these can be worn much longer than normal underwear without needing to be washed. At some point I thought: why buy anything other than merino? I ordered more, and will order more again. I hope they keep making these and keep them in stock.
