It's been steadily going more mainstream, but it's still mostly cottage manufacturers. Granite Gear makes some stuff sacks out of it and Terra Nova has introduced a cuben tent lately. I suspect it will grow a bit more mainstream yet, but it won't take over the mainstream because it's too expensive and it feels a bit too delicate to sell to a traditional user. I doubt you'll see cuben tent fly's from TNF, MSR and Mtn Hardware any time soon.
To have a serious chance of really taking over the mainstream, Cubic Tech would likely need to drop their prices by half. Even then, it's hard to say if gear makers would want to sell something to the masses that feels more delicate than heavier nylon tents etc. There might be a middle ground where gear makers would use heavier 1.2oz cuben for a lot of stuff like tarps and tent flys if the price was lowered. I also suspect mainstream manufacturers would balk at having to change their production techniques after sewing everything for decades.
A typical 2 person tent fly uses roughly 8 yards of cuben, which is $200 from Cubic Tech. There's no way mainstream manufacturers are going to pay that. If they were doing this, they'd also want carbon poles and cutting edge materials for the inner tent, which would probably bring their cost for the tent to near $500, which means it would be on sale at the local store for $1000. You see this with the Big Sky Cuben Mirage tent at $999 MSRP.
As it pertains to us lightweight hikers, there is getting to be a huge number of options. Makers of cuben stuff that I can think of are:
- Mountain Laurel Designs (tarps, mids, stuff sacks, poncho tarp)
- Zpacks (tarps/packs/tarp tent, stuff sacks)
- Hyperlight Mtn Gear (tarps/tents, pack, stuff sack)
- MountainFitter (stuff sacks, dry bags, custom tarps by request)
- BPL (Stuff sacks, Tarps)
- Terra Nova (1 person tent)
- Big Sky (2 person tent)
- enLIGHTened equipment (quilts)
The only cuben gear that I'd like that isn't currently available is clothing. I'd like a 2-3oz cuben rain jacket to carry as back up on trips where the forecast looks too good to carry a heavier rain jacket. I'd also like cuben gators (1.2oz cuben) and rain pants. Other people would likely like cuben vapor barrier clothing.
