Really bad chafing

I like runderwear stuff and thought I'd try these as they were in sale. Extremely comfy but I've just used a pair on a 2 hour run and have bad chafing on my inner thigh. So not the best for me. I would not recommend these for running

Bought for other half

Seem to do the job ok. Time will tell, bought as an upgrade to his other runderwear undies!

Only 45% merino!

I just received these "merino" wool underwear, thinking they would be merino wool. They fit fine, and I have yet to see how they perform with sweat and odor, but can they really credibly claim merino wool? They're 45% merino wool and 40% polyester, which I only discovered when looking at the actual garment. The website touts the benefits of merino wool as if the product is primarily merino. Coming back to the site, I can't seem to find the merino content listed anywhere. Perhaps, these should be advertised as polyester underwear, and they should have a full spread articulating the wonderful merits of polyester? Don't buy these if you're expecting to get a garment that is primarily merino wool.

Hey Teddy,

Thanks for your review, Our co-founder Jamie who is a marathon runner wanted to develop a pair of seamless merino underwear for his own running. Through years of development the selected yarn was a blend of merino and Thermocool which is a thermoregulation polyester (not regular polyester) keeping you cool when hot but also warm when running in colder environments. The yarn is a premium yarn from Südwolle.

I am looking forward to hearing your feedback after you have trialled and we of course take on board your comments and we must communicate the above clearer on our website. I really appreciate the feedback and look forward to yours.
