High Sierra Topix

I use a very light crop top cotton undershirt (a girly thing - do not know if such is available for men) and wear it under my synthetic long sleeved hiking shirt. The undershirt does not count as insulation (the "cotton kills" statement only is true if you count on it for insulation). I wash it every day when I get to camp, take a dip in the creek, then put on fleece or wool. My husband simply hikes in regular cotton T-shirts. He washes it every night and if it is not dry by AM, so what - he just puts it on and soon dries as he warms up. Since I have to sleep in the tent next to him, I banned his synthetic shirts long ago! Now if I could just get him to stop snoring.

Good luck with that! My crew is generally 4 guys. 2 of us snore large. Yes, I'm one. I snore less at altitude, because I never sleep well anyway. Back to topic, a clean body leads to a better night's sleep.

Body Sensors by Terramar (wool/synthetic blend) baselayers rule!

Not stinky, very comfy

The only stink-free base layer I have that is synthetic is an ExOfficio short sleeve t-shirt that has the silver-impregnated threads. That is the only synthetic base layer that I will take backpacking. However, lately, wool is my base layer of choice. All of my wool base layers have proven to be stink free. I have found wool to be my best option, as it is cool in the heat, and warm in the cold, and it does not stink. I have some IceBreaker short sleeve t-shirts, and a SmartWool short sleeve t, as well as a long sleeve t with the zip front, and these have all performed well for multiple days without washing/rinsing. I have worn the same pair of merino wool socks for four days straight, without any funk - and yes, I put them to my nose for the funk test - result is pass, with flying colors. However, as Rlown said, yes those socks can stand on their own, without my feet in them, after about the second day.

I have a variety of synthetic shirts and none of them hold my stink. I bathe when I can, but its not something I find absolutely necessary, so a few hiking buds have told me to go for a swim. I don't take any dairy products, which may change how I smell. I do notice a dairy smell on other people. Perhaps milk breakdown components make stink stick.

I found that light weight or tropical gaiters help keep the dirt out of my boots and my socks stay much cleaner. I bought them for a trip on the Lost Coast and found they made such a difference that I use them most anywhere. Worth the extra few minutes they take to put on each morning.
