MT23 Muay Thai Shorts URBAN CAMO

I like these trunks, but I do have a few critiques. I bought these trunks because they were some of the only ones I could find made from natural materials, cotton in this case, but it turns out that the waistband uses satin on the outside. The inside of the waistband is cotton though so this is not a major concern, but ideally I do wish The outside of the waistband was cotton as well. The one major critique I have is that the dye used to color the shorts seems to be continually coming out of the trunks when I wash them, which I do by hand after every training session. I use warm water and cold may be what is recommended, but my thought is that when I wear them I myself get hot and the my sweat is at least warm. I'd prefer that my body were in contact with fabric that didn't leech dye. I'm considering a vinegar soak or maybe even something more drastic to get all the dye that might leech out of them out. Washing has been yielding somewhat less dye each time but they still leech a significant amount. That's my main critique. I love the cut, the fabric is breathable but durable, and the patch work seems to be of good quality. I have a strong preference for natural materials, so if you guys could use natural dyes as well I'd love that, it doesn't matter to me that that might limit the color options. I'd also be extremely pleased to see hemp or Tencel offerings also. Tencel from what I understand can be blended with cotton (or maybe hemp?) for an all natural fabric that is flexible and can stretch. Thank you guys for making trunks with natural materials!
