@AKDoc: Would you mind throwing me some insight into my layering system? I'm looking at buying the Guide or Axis hybrid, but want to make sure that they're not going to be too cold. I'm going to be in the Southern Brooks Range mid-late September and expecting temps anywhere from 0 to 60, and rain/snow/sunshine/heavy winds (pretty much the whole kitchen sink of weather). I'm planning on running a merino base, Swazi "The Hood", then either the Guide or the Axis Hybrid. I have a Eddie Bauer puffy to throw on over all of that if needed (or around camp). I'll also have some rain gear to go over the top of it all. TIA for any insight/tips!
I think you're going in the right direction with the list you shared. Not sure if you're humping everything on your back every day or setting-up camp at a drop-off point and then day-hiking from there each day. I'm going to assume the latter...
Personally, I'd do the Axis jacket as opposed to the guide...the extra water protection panels are pretty helpful, and I think it's more wind resistant and layers better than the Guide, especially around the neck. I also think it packs a bit more friendly than the guide. I'm 5'10", 185lbs, and always between a L or XL with KUIU jackets. I went with an XL with the Axis and it's a perfect fit for me. BTW, the Axis pants are terrific as well, and they have become pretty much all I wear now each fall...water-proof butt and knee panels, and the hip-vent zippers are all really helpful to have.
For layers, I'm always wearing lite merino tops/bottoms, which I also sleep in every night. I also have a set that's a bit heavier, but I seldom wear them. I have a first generation Kenai jacket and a first generation Chinook jacket...I wear either one of them over my base top, depending on wx and what the plan is. They no longer make those jackets, and the first generation Kenai jacket was pretty different in design and fit. For clarity, the Chinook jacket is lighter and has some lite matrix insulation on the inside...the Kenai has more insulation. Both those jackets have pit-zips. The Axis jacket over either one of those has always worked very well for me. I have the KUIU down puffy hooded jacket (and pants) that I can put on over all that if needed...typically when eating dinner in the dark! BTW...putting your Mountain House or Peak refuel meal between layers of your jackets is a pretty nice thing while it's "cooking" in the pouch (just be sure you sealed it well and relax/don't move around while it's cooking...learned that the hard way!)
Think about maybe adding a vest to your list...something lite and packable...I typically have one with me, but not always used.
Make sure your rain gear is truly good at doing its job...you might be living in them, as well as a final defense in heavy and cold wind.
Always glad to help...
