I'm in the market for a new paddling top for use with Farmer John.
Drytop not needed because I have drysuit.

Campmor sells the Kokatat Super Breeze made of Tropos fabric for $85.
Several websites say Tropos is nylon with "custom" urethane coating
inside and DWR spray outside.

NRS sells the Endurance jacket made of Wavetex for $70, described here
as nylon coated with breathable urethane inside and DWR spray outside.

In general, ya think these fabrics have approximately equal lifespan?
Perhaps they are even the same fabric.

My Patagonia paddling top had a white hypalon-like coating inside
that didn't last very long; quite a disappointment. I think my old
cheapo Kokatat with urethane coating lasted longer.

The NRS jacket has a weird upper-arm pocket, whereas the Kokatat has
a traditional mesh pocket on the chest. Guess I prefer the Kokatat.
Other jacket ideas welcome.
