Judging by the number of males who have reviewed this and suspecting there are a few others who are, perhaps too embarrassed to review, I wonder if it is time Runderwear made a male G-String?
I was hunting for underwear that did not ride up my glutes on running. Tried a few non-runner's thongs but the Runderwear Women's G-String beats them all. The size guide worked well (XL in may case, 32-37 - I refuse to give my bust size...). No chafing, no riding up my glutes, a comfortable joy to wear. Excellent product.

In search of a male version I wa led to try these from a runderwear employee ..male ...
Although I havnt used them for running in as of yet I can’t review them fully.
It does feel odd wearing women’s underwear but cannot find a male version anywhere made with the sweat wicking material needed to keep the goods cool enough during a run without being restricted everywhere else while wearing compression shorts. Commando isn’t good enough.
These feel good quality and smooth material, really odd fitting though with no visible POUCH to keep things in one place and a bit more material round sides and back thanks usually in a male thong.. could prove to be a real sweat trap but will reserve judgement.
I will probably find these good for the job and they will forever be discontinued forever. They have said a male version is in the pipeline so I can’t wait to try that one out.
I’m sure for you ladies out there.. these will be a really soft comfortable set of underwear.

These are super comfy. I've never had an uncomfortable run in these and haven't found anything better to run in. Just the right amount of support under running tights and an aid to modesty. I also wear these for cycling under cycle shorts [yeah, I know people say go commando...] You don't know they are on but they help keep things out of the way. These work great for guys so not my first pack :)

High quality product which is accurately described and fairly priced. Website is easy to use and swift delivery post purchase.
Please stop using the plastic bag for packaging.

An ad for Runderwear popped up on my Facebook page and I was intrigued. The products looked interesting but like most running-centric manufacturers Runderwear doesn't offer a G-string for specifically for men (I personally prefer this cut for running in). However, reading through the reviews I learnt that the Women's G-string had been suggested for, and reviewed as suitable for men also. So I went ahead and purchased. And so glad I did, as echoed by the other reviewers they fit great and are supremely comfortable. This is my second purchase and I went for size M this time which fit me perfectly, In fact they're so good, I wear them every day, not just for running :) Will definitely recommend to friends and buy again!
