Every year I do an 8 day trip; usually by the 3rd day I can smell my underwear (and it's baaad). I've tried several brands of boxers (REI, Patagonia) to no avail. After hearing about the odor suppressing powers of bamboo, I purchased a pair – "Marrikas Viscose" – $40 including shipping.
I used them on a very sweaty 8-day trip.
The positive:
They did not smell after 5 sweaty days. No funk!
The negative:
They're not quick-dry; it took over an hour in the sun to dry them after washing.
Some of the stitching came out; durability may be an issue.
Kind of pricey.
Prior to this trip, I'd had good luck with silk boxers, but they only lasted 2 seasons.
I've never tried silver-ion technology, maybe next year. Don't want to go commando.
Any thoughts?
