Ultralight is a philosophy. The philosophy is about eliminating all unnecessary items and/or weight. The UL community on Massdrop has way too many items that are blatantly outside the UL philosophy. About half of the recent drops listed under "Ultralight" are, in my opinion, far from anything a ULer would bring on a trip.
Yes, you could have a couple non-UL items and still be under 15lbs BPW, I understand that. That's why UL is a philosophy. In my opinion it's a scummy marketing/PR decision to call the community "Ultralight" when there are so many items that are blatantly not intended for a UL audience. Lanterns, metal water bottles, knives, etc do not belong in Ultralight discussions, just to name a few.
I think Massdrop would better serve a wider audience if it renamed the current one to simply "Backpacking", OR created a separate one to keep the UL items together and the non-UL items somewhere I don't have to look at them. If there can be "Tech" and "Mech Keys", there can be "Backpacking" and "Ultralight".
For the record, Massdrop's own "Ultralight 101" states 10 lbs as the qualifying BPW for Ultralight. Just think about that for a second when you look at some of the items they list.
