Good value and comfortable.
Very comfy shorts
Well fitting comfortably soft bamboo at fabulous prices and quick delivery great buy
Very comfortable trunks at a fraction of the price of another company (the one with the annoying adverts).
Good quality and comfortable
Previously bought bamboo boxers from another company with an Italian sounding name, and they are thicker fabric and better made than the ones from Spairs, which are thin, not very supportive and one pair had poor stitching out of the box. The Spairs ones were less expensive, but really not worth it. I will buy more of the first ones.
A good quality product very nice to wear
