The color on the website for Bitterbrush is accurate. Any digitial image isn't always going to 100% align with what they look like in person, but it's close.
I'm curious about your thoughts on the internal belt and knee pads. On the internal belt, I'm open to doing it, but we have not found a ladderlock buckle that doesn't slip under a heavy pack, which is when you need your belt to not be slipping the most. I understand some people like them and the rubbing issue under a pack, but most of our survey feedback was ambivalent or didn't care at all about the built in belt. And my personal experience is the built in belts are ok but not great, and if they do slip you have to remove it so you can use a differnt belt (or use suspenders).
And on the knee pads this is an interesting one. I'm open to it but it was a very low priority for our survey respondants if they cared at all. We will offer knee pad compatible pants in the future, but just an FYI for why. And to your question about why we wouldn't have optional knee pads. If you're going to make room for an internal knee pad you have to create space for it in the leg sizing around the lower thigh, knee and calf area, and to do that you have to make the legs baggier or else the knee pad will feel too restricting inside the pants. We didn't want either of these pants in particular to be baggy in the leg as that creates excess fabric, which causes fabric "swishing", which makes for more noise. Just wanted you to understand the rationale.
On size, we certainly tried to err slightly longer, knowing some people can hem if need be, but it's harder to sew on a couple extra inches of fabric! If you try them out and they don't fit, you can always return.
I appreciate the feedback and let me know if you have any other questions.
