Just finished dying my pack, thanks to Ken Thompson's instructions here:

Here's the re-cap:
2 gallons boiled water, 1 gallon hot water, 1 bottle black RIT dye.
Mixed everything into a 5 gallon bucket. Submerged pack, stirred, put a rock on top to keep it down. I didn't bother wrapping the bucket or using a lid. Removed/shifted/stirred the pack every ~10 minutes for a little under an hour. Rinsed with a garden hose inside and out until it ran clear, then ran it through my top-loading washer on cold for a 2 rinse cycle with a little detergent. Dried it on low (no heat) for a few minutes, both inside and out. Done. Best $3 I've spent on gear in a while…like many, I've never liked the ULA green dyneema. I know they offer custom colors now, but everything is in cordura (though I likely will be buying a CDT in multi cam soon).

Thanks Ken!!
