I was excited to try these underwear, given the purported benefits of hemp fabric. Hemp has properties similar to those of merino wool, but with a lot of environmental and social upside. I think these boxer briefs are a success. WAMA's sizing advice might seem odd at first glance but is actually very useful. Usually I'm an M or an L and WAMA's size chart says I'm an XL, so I went with their advice. Their advice was correct; these boxer briefs fit like a glove. I appreciate that the underwear arrives in recyclable packaging and with minimal or no plastic waste accompanying. The underwear is very soft and breathable, even in hot weather (I live in Kansas, which has hot and humid summers), and therefore it's quite comfortable. So I like these a lot, and I'm giving five stars because I think these are good underwear that are just as advertised. I do have some friendly criticisms. I would describe the fabric as midweight, if that matters to you. I had hoped for a slightly more lightweight fabric, but these underwear remain breathable and comfortable even in hot weather and I expect the fabric weight will lend it some durability for the future. I also think the midweight fabric lends the underwear some structure, which has its advantages; I have some other, more lightweight boxer briefs made from modal fabric that are lightweight, but they tend to stretch, bag out, lose their shape, and then ride up over the course of the day. Like all natural fiber fabrics, these WAMA's do relax and give a little bit with wear, but they don't really lose their shape and then ride up. I would personally prefer a slightly longer leg, which would combat the tendency to ride up, but that's a personal preference. These underwear are very nice with lots of advantages and I think they are definitely worth a purchase. I look forward to seeing what else WAMA comes up with.
