I just bought a "new" pack, a 2010 Gossamer Gear Mariposa, in silnylon. I also have a MLD Prophet in silnylon and spinnaker, as well as a G4. Silnylon packs like these and many more used to be available from places like Gossamer Gear and MLD and were well made, light weight, and affordable. The G4 has been with me for 3 seasons and I inspected it today. It looks brand new. I am careful with my gear but not obsessive. The G4 has seen it share of overgrown trails and abuse. Granted, I don't bushwhack or climb with mine, but how many UL backpackers do? Now dyneema, VX, cuben and hybrid-cuben rule. The packs from MLD and Gossamer Gear are now heavier and lot more expensive. The G4 looks like the only silnylon pack left standing. It was not lost on me that at the same time Gossamer Gear rolled out their more expensive dyneema packs they lost the word "affordable" from their logo.
Did people really find the silnylon packs were just too wimpy for UL backpacking? Was this move away from silnylon made based on customer feed back or, shudder, focus groups? Or was it a business and marketing decision, selling on us on a level of durability we might never need for a much greater price than we were paying? Would people still buy packs like the MLD Prophet, the GG Mariposa, or the GG Murmur, if they were offered as a cheaper alternative next to their dyneema counterparts?
