I've worn Patagonia capilene dayhiking in the Smokies for a few years. I detect no odor after 1 day which isn't much of a test. I did wear the same shirt 2 days in a row this year to test - still no odor. I also wore the First Lite Minerett Aerowool for 3 straight days in colder temps a few weeks back. I had a few sweaty days in that shirt - no odor at all after 3 days. I'm hoping someone chimes in with 3+ days of capilene wear. I can vouch for multiple day wear on FL Minerett and Outdoor Research Sequence base layers. No odor after 3 days of use.
Kuiu is having a sale, started today, on alot of base layer clothes in gray and brown. I ordered a Peleton 200 hoody, Peleton 130 crew, and Peleton 200 zip off bottoms. Be trying those both out later this month - we have a couple of big hikes to do. Probably won't get to the multiple day thing till spring when we have a couple of backpack trips in the works.
