As an experiment, I recently bought some M&S Ultra Fit Hipster underwear. A pack of 3 costs £15. Compared with, say, X-Bionic Energizer Boxer Shorts at £20.99 each, the M&S hipsters are good value. They are 90% polyester, 10% elastene. I’ve not tested them thoroughly yet, so I can’t tell how good they are at wicking or their odour resistance, but they are extremely comfortable. They are pleasantly clingy without being tight. The wide waist band is also very comfy. Weight is 78g, slightly heavier than the X-bionic or my Haglofs briefs which are 52g. At £5 each, they seem very good value. No pictures as I can’t copy one fromthe M&S website.
