I was curious about the new fabric, which seems to replace stuff in both the Atom and Squamish lines and reached out to a friend who works at Dead Bird.
Their response: " The Tyono fabric is stronger and tighter, so more wind- resistant than Gossamera. The Atoms also switched to this. In 2 deniers…20&30. The Squamish uses the 30, which is used in the atom ar and the more heavily insulated atoms. The LTs use the 20."
When I asked about breathability they said "I'm still rocking an old one but internal peeps say breathability is the same, but way softer hand and better durability. And yes, still has PU to allow DWR treatment. "
Has anyone picked one up?
