Thought this was interesting. I noticed it on the Nordic co-pilot I purchased recently. Thought it was Dyneema, but it has this tag on it. Interior is Steel Dyneema, I can't find anything other than perhaps the trim that would be 1050. It's also the only 400d Dyneema I've got so I can't compare to another bag. What's also curious is that it doesn't have the X grid pattern that the 200 has.
Guessing an "oops?"
