Long Time Customer

I have been buying from the Mosmann people for years now. They sell good quality underwear and with the worldwide free shipping option. It is just like buying locally or even cheaper ( I live in Hungary). They have great multipack special offers, cool designs and if there is a problem or issue their customer service is quick to respond and help. Recommended.

Large is actually large!

I've bought, from other makers, underwear labelled X-large that were actually medium 🙁 Mosmann fits perfect, fabric is soft & range of patterns is fun.

Best Swim Shorts

Mosmann men’s swim shorts are an absolute godsend! They’re super comfy. - I don’t just wear mine in the water, I wear them when ever I want a bloody comfy pair of shorts. They dry quickly, which is a bonus especially come spring and summer here in Australia. I bought my first pair around 12 months ago and I now own 5...I’m loving the product and designs. I highly recommend them to all guys who want amazing pair of shorts that fit flawlessly and make you look amazing, they hug the but too...ladies
