In the market for a new rain shell for 2019 PCT thru hike. Am considering the following and would like the group’s expert advice:
- Patagonia M10 Anorak. In 2016 I used the M10 full-zip for 8.19 oz; the anorak is 7oz. It is one of only two 3-layer jackets on this list. From my experience of the M10, this jacket was great and but for my reading about lighter options, I would have just purchased the M10. Note that I ditched my windshirt about half-way through my hike and used the M10 for that purpose, when needed. My biggest concern with the new M10 is that it isn’t a full zip — for temperature regulation in 2016 I often had my M10 fully unzipped or almost nearly so.
- Berghaus Men’s Hyper 100 Shell. This is the lightest contender, at a whopping 3.5 oz. This also claims to be a 3 layer jacket. Website claims breathability of 55,000gm2+MVTR and a hydrostatic head of 20,000 mm. Based on weight alone (and given that I probably had to deal with 20 days of rain out of my 150 day thru hike), I’m leaning toward this choice, although I read one user complaining that in torrential downpours, the jacket zipper is a weak link and caused this user to get wet through the zipped up zipper. Anybody experienced this?
- ZPacks Vertice. An interesting pick because it does not rely on DWR, so it shouldn’t wet out like the first two choices. 6.2 oz, its heavier than the Berghaus but lighter than the M10. It has pit zips. Claimed breathability of 56,000 and a 20,000 HH – similar to Berghaus.
- HMG Shell. Also not dependent on DWR. Weighs 5.8 oz. Claimed breathability of 30,000 and a 10,000 HH. Aside from being a bit lighter, would seem to be inferior to ZPacks, which also uses DCF.
- Arc’teryx Norvan SL. Weighs 4.4 oz, but I can’t find breathability or HH ratings on website. I don’t think it’s a 3 layer jacket. Also, I noticed one reviewer who had the same complaint as the user had above with regard to the Berghaus — apparently for this reviewer, extended rain led to leaks through the zipper.
- LuL Micro10 Rain Shell. Weighs 4.10 oz. Claims breathability of 30,000 and HH of 10,000. 2.5 layer. Note that he has similarly weighted shells made out of Silpoly 4K and Pertex Shield. If Luke’s is your pick, I’d love to know the differences between these three.
So, here are my questions (please don’t factor in price when answering and keep in mind I’m trying to determine the best piece of gear for a PCT thru hike, with its attendant conditions):
- Of the above, what would you pick and why?
- Are there other jackets I should consider instead, either due to having a lighter weight or better performance than the jackets listed above?
- Any idea what is the CFM of the above jackets? I’m still not sure what this number means, but it’s on my “to do” list.
- What do you think about using the above rain shells to double as wind shirt? Note that I did this with my M10 in 2016 and it worked out fine. A lot of dedicated wind shirt advocates on here, though, so I may revisit that decision.
- Finally, I’ve always thought that 3-layer rain jackets would hold up better over time than 2.5 or 2 layer. Is this enough reason to pick the M10 or Berghaus Hyper over the other picks, which are not full 3 layer jackets?
Thanks for your help!
