Not entirely true. Frogg Toggs are definitely both. Plus they are super cheap and light. Downsides are durability and lack of stylishness. Their "fabric" is more like a fluffy version of tyvek than a fabric, which is how it manages to actually be breathable.
I guess you and I have different ideas on "breathable" and "waterproof". Even the 2.5 layer jackets like Paclite will loose their breathable ability when the DWR starts wearing off and the fabric wets out. I bit the bullet and went with Mountain Hardwear's Dry Q. Elite and so far it's completely waterproof and breathes well, but it ain't cheap unfortunately and even calling that breathable is a stretch in my opinion.
For those not familiar with Outdoor Research Helium II
I have the OR Helium II, it rocks! I use a Marmot Precip Medium 12oz
for cool weather protection over my layers.
The Outdoor Research Helium II rain jacket is my go to for summer
rain gear. It is for the minimalist weighing 5.6oz for medium,
nylon-ripstop with Pertex rain shell that is so lightweight.
It serves me double duty as a wind and/or waterproof jacket.
It has a waist drawcord to cinch. It is perfect for wearing
in warmer weather when you need to carry a waterproof hooded
jacket and when I want to keep my gear as lightweight and compact
as possible. The hood has somewhat of stiff cap cover bill.
It lacks side pockets and pit zips to save weight.
As for breathability, just regulate by unzipping the water
resistant/waterproof zipper to let air in and around. It has elastic
around wrist as opposed to having added velcro to lock closed. If
you lift your arms up, water drains down the sleeve from wrist area.
It does fold into a internal pocket. It has adjustable elastic
on back of hood to cinch around your face, but does not fit tight
causing it to allow rain in and down around your face which I
don't mind during warm weather but use my 12oz Marmot Precip for
cold rainy weather. It is appealing to me for backpacking and
hiking as a lightweight gear solution but is pricey. It is made
with 30D nylon ripstop (2.5 layer Pertex Shield+).
OR's Helium II is waterproof and has fully taped seams and has
a small chest pocket with a water resistent zipper. It has a
small inner pocket 5"x6" which the jacket can be folded into
for a small storage which I love. This is a great warm weather
rain shell and for an ounce counter like me its lightweight
for the value. It is so small and light, it always stays in
my pack.
What's their option in this category? Would you please add it for us?
I know their gear costs a lot, but I've never heard one bad thing said about it from someone who had it.
Ok, before we all go and vote let's talk about actual dryness and breathability. I recently did a lot of research on this and went with the Helium II (I didn't look at a number of these jackets) because of the reviews. A lot of the lighter jackets either don't breathe or won't keep you dry in real rain... I'm curious to hear more from people who have used these.
I really like the fit of Berghaus and Rab clothing, so nice to see them currently at the top of this poll. The arms and torso tends to run longer than average, and the torso isn't so boxy like some of the big american brands.
