Sustainable Running Pants

Hi, all. I’m (F) looking for women’s or unisex (or men’s, really) running pants—please, no leggings—that have a high proportion of natural fibres. (I’m guessing most have at least a small percentage of synthetics for moisture-wicking purposes, etc.)

I’m finding this additionally challenging because I’m tall and, given my curvier proportions, I’m looking for pants with a higher rise and looser fit through the hips and thighs.

Ideally, the pants are available from a Canadian or American retailer, because import duties from overseas retailers can be prohibitively expensive.

I recognize these are many “boxes” to tick. I’ll be grateful for any suggestions.
