SuperUltralight 3 Season Gear List

Useless w/o context.
This is not a 3 season list in the West— more of a late Summer list. Sounds like you are not expecting much in the way of precip ( w/ the semi-waterproof Isotope). It will make for a stuffy windshell, as well.
Not the all-in-one shell of my choice.

Sorry, I forgot to put this on the gear list but this is a three season gear list for the southeast U.S.

I would have bought a GoLite Virga rain jacket but I don’t know if they are even out yet- any suggestions for rain/windproof jackets?

Anon,

I like the minimalist fastpacking list.
It could use some work, I just posted a minimal gearlist for the same weight including in clothing, a full wind suit, a full extra base layer, warm hat, extra socks, insul. vest.

You can not always rely on the down gear, so you have to have a clothing list that will keep you warm down to at least 50 or 40 degrees if needed. and yes it must be breathable.

and for a small load your g6 will be too big and will sagg pulling onyour shoulders.
check out the MLD packs

OR zealot jacket?

I’ve no personal experience in SE conditions, but assuming humidity and primarily trail travel, I would opt for a seperate highly breathable windshell ( Patagonia Houdini, Marmot Ion, something w/ a full zip for maximum venting options) and a UL Poncho ( BMW spinn-lite, Mtn Laurel Design). This combined set up would weigh from 8-11 oz. and would double as your shelter. You would be dialed in for comfort over a broader range of conditions than relying on the Isotope.

Alternatively, you could opt for a Dropstoppers or Rainshield microporous polypropylene rainsuit— waterproof, highly breathable and it won’t break the bank. Don’t bushwack in them as they are fragile.
