The fabric is a three layer laminate with high strength Dyneema fibers
sandwiched between eVent waterproof breathable membranes. In our testing the strength, waterproofness, and
breathability have all proved to be very good. The jackets are breathable
enough to sleep in or hike in if it is cold out without getting

updated with a micro-checkered pattern in the eVent membrane for
even better breathability!

Joe and Sheryl's WPB Jacket Review:
In 2012-2013 we thru-hiked the Te Araroa Trail in New Zealand. It was about
1,900 miles (3,054K) and it took us 120 days to complete. We both
carried ZPacks WPB Cuben Fiber Jackets and Pants (Gear list).
Our jackets were made from the original generation fabric, without the
new vapor transfer improvement.
New Zealand is a wet country, especially on the north island where it
is usually warm and wet year round. We had plenty of opportunity to test our
jackets and pants, including several days where we had to wear the
rain suits all day long, from the time we broke camp to when we
pitched camp the following night.
I personally thought the breathability of the jacket was quite good.
As long as the temperature stayed below 60F (15C) I was comfortable
and stayed dry from sweat. In warmer weather it was too hot to hike in
any jacket, so of course I did sweat some. The jacket was also
comfortable to wear as a wind shirt, or to sleep in, as long as the
outside temperature was appropriate.
Sheryl sweats more than I do. I would say her comfort zone was
probably more like 50F (10C). Above that and she would get a little
damp from perspiration. This was especially evident under her belt,
shoulder straps, and sternum strap where the moisture could not
escape. I don't think this was any fault of the jacket, any
warm shirt or jacket has the same effect on her.
Neither of us had
any issues with rain getting in from the outside. The material is
waterproof, and I stayed completely dry as long as the temperature was
Neither of us had the Armpit Zips option. I never missed them, but
Sheryl wished she had them for venting.
The jackets held up pretty well over 1,900 miles. We never had to do
any repairs, but if we had gotten a puncture or tear,
Cuben Tape would have patched it up easily.
Just like normal Cuben Fiber, the material is rip-stop and does not
We did get some visible wear marks under the shoulder straps and other
places where the jacket rubbed against our packs, but those spots did
not leak through. The material is a three layer laminate, with
Black in the center, and White layers on the inside and outside. This
gives the fabric a mottled Heather Gray look when it is new, however
as the outside gets worn the Black center layer shows through more.
This is to be expected and should be considered normal. It is only
a cosmetic issue, we did not experience any leaking on our jackets.
