Excellent fit. Very comfortable.

After trying other brands of merino underwear these are my go to boxers. Very comfortable and superb fit. Have had a number pairs for some time. With correct washing using merino specific wash liquid and no softener they have retained shape and soft feel. No piling of fabric. Expensive -yes, but investment is worth it (occasional sale offers worth looking out for).

Thanks for the feedback, Peter! Great to hear the boxers are your top choice.

Good Quality Product

To get a looser "boxer" look and feel I ordered an L ( I normally wear S maybe M in other brands W-31) . Comfortable out of the box and after washes. What sets these apart is the weight of the fabric, quality of the sewing, and the comfort of the waist band. I have tried several brands of merino wool over the years, and many (even Patagonia) made boxers that are too thin to holdup against multiple washes . Isobaa boxers can be worn for several days without becoming unpleasant ,thus excellent for travel .

Dear David,

We're so grateful for your wonderful review, and thank you for choosing our products.

We're thrilled to hear that you appreciate the quality of our product, and that you find the fabric weight, sewing quality, and waistband comfort to be exceptional.

We understand that sizing can be tricky when shopping online, so we're glad that you found our boxers to be comfortable straight out of the box, and after multiple washes. We're delighted to hear that our boxers stand up to your expectations for Merino wool products.

Thank you again for choosing Isobaa, and we hope that you'll continue to enjoy our products for years to come.

Best regards,
Team Isobaa

Top quality garments!

Delivery was excellent and my package arrived within two days. The boxers are of a very good quality and I am delighted with my purchase. Thank you!

great quality

I bought some hiking socks and some merino boxers. The quality is great and they wash well without losing their shape or shrinking. (I do wash them on a low setting with a wool detergent as well).This is my second purchase of these items, basically to stock up! They're great for everyday wear as well as more outdoorsy activities. Highly recommended
