Runderwear Men's Merino Briefs | Chafe-Free Performance Underwear with Premium Merino Wool

Very comfortable briefs. They have quite a bit of stretch and I think I'm at bottom end for XL (I'm 38"). Just enough support for people who don't like the lack of support found in boxers. If they were a bit less expensive I'd buy a couple more pairs and wear them every day.

So glad I found this product! Lightweight, comfortable and well made, this underwear will be my choice in future. Highly reccommended. No problems or issues with this company either and will definitely use them again.

Love them for cycling

I got a size up, L instead of M, and these were still much too tight around the legs. I would have to get three sizes up for these to be a comfortable fit.. Also I thought these would be made of 100% merino wool but they are only 40% merino

If I could give these less than one star, I would. Supposedly chafe-free, these briefs actually gave me chafing that I'd never had before. And now I am in a constant battle to try and heal the affected area before I go out for a run again - often twice a day. There's no doubt I'll now line up for the Frankfurt Marathon in October, already chafed. God knows what I'll look like by the end!

I run with thoseThey breathe and makes u feel great

Quite pricey but work really well with running tights

Nice and comfy

Wird zwar als Merino Slip angepriesen, ist aber zu 55% aus Plastik.Genaue Zusammensetzung: 45% Merinowolle, 40% Polyester, 10% Polyamide, 5% ElastanIrreführende Produktbeschreibung die nur dazu führt, den Artikel wieder zurückzuschicken.Selbst auf der Englischen Homepage des Herstellers werden keine Informationen zu den verwendeten Materialien angegeben. Die wissen wohl warum.Für 30€ lieber die Slips von Icebreaker kaufen, da ist wenigstens 83% Merinowolle enthalten.

Great underwear, perfect for exercise. Comfortable, great quality, highly recommended

I've just completed my first run in my new Runderwear briefs and I must say that I was expecting them to be good - but not this good. They are very light and comfortable providing you with a snug fit to hold everything in place while running, but the high quality elastic is so light than it barely feels like you have anything under your running shorts. They are so comfortable that I can see myself wanting to wear these all of the time not just while running. I highly recommend these briefs as the most comfortable pair of jocks you could imagine.
