prm - interesting observations. I've found the Kuiu Guide to be pretty warm in most situations. I'm wondering how well the MH jacket breathes. Some of those type garments feel really good at first because they don't breathe well and basically trap alot of moist heat. I'd be curious how the layering worked after being sweaty and sitting still for a couple hours.
On the 2 base layers - that's my plan as well. I've been trying out that system all fall and really like it. Picked up a 200 Peleton hoody today and am anxious to try it out on a couple of hikes.
Thanks for the report.
