To answer my own question I found that the Smartwool RBX Ultralight socks seem to be about as light as one can go at 1.5 oz.

These make fine sleep socks (1.5oz in medium).

Yes, but the RBX socks can double as regular hike socks.

“ones that are always either on when Im asleep or in the pack”

Didn’t understand your wording to include hiking. Have been using the P-Down socks with the very thin Smartwool liner socks over them for hiking. Have also tried sandwiching the P-Down socks between two pairs of the very thin Smartwool liners. Both approaches appear to greatly extend the life of the P-Down socks, but need more testing. Heels have not worn out yet as has happened when P-Down socks used alone. Three layer combination no thicker than some hiking socks. Have not tried the three layer approach in warm weather. May be too warm?

Go for it. Those RBX socks won’t be as warm as either the possum down socks or the 200 weight fleece. Your original post said you wanted sleep socks not double duty sleep/hike socks.

You are right. Originally I was thinking of just having sleep socks, but then all this talk of multi-duty led me to alter slightly the concept as I thought about it.

Good to hear they are holding up.

I don’t consider the Smartwool socks liner socks. I only use one pair of socks (not a sock and a liner sock). I use them to sleep in and hike. Because they are so light, I carry a pair for each day – fresh socks are a luxury I can afford at a little over an oz per pair. I put on the next day’s hiking socks when I go to bed, not to keep my feet warm but to keep the bag cleaner.

I like either of the above. I’ve seen slightly lower prices than those posted at Sierra Trading Post on the Smartwool sock. You might check for other deals online. I’ve bought both for about $6 per pair.

The one disadvantage of these socks is they wear out much faster.
