Anyone tried REI’s silk baselayer?

My wife and I both have a set of long silk underwear that we bought at REI and love them. We almost always sleep in them and if it is too warm crack open the bags because the silk makes sleeping so much more comfortable. They are our base layer when it is cold enough but in modest spring and fall weather we shed them before we start hiking and use two other layers where the outer one can be peeled off. In very cold weather they are too light of course.

I love mine. I sleep in them every night to protect the bedding from my oily skin. I've never used them backpacking, however. They've held up really well until my wife washed her bra with them. Now they have holes but the holes haven't worsened over time. The stretch weave of these is great.

It's hard to beat the weight, and they feel great on the skin.

I haven't actually put them on my postal scale, but they make my favorite light, dry clothes to change into in camp.

Whoa! Thanks for the wholehearted response! That confirms my thoughts while looking at then in the store.

I have since seen Terramar brand silks,sold by Sirra Trading Post! at about 1/2 the price of the REI's. I wonder if I'll be glad I saved the money or sorry I made a bad decision?

I definitely want them to be lightweight to protect the sleeping bag in summer, not for insulation

Michael,
You should be fine with the Terramars. I happily used them for several years before switching to L. L. Bean's version to save another .5 oz. Sick, huh? Now THAT is a decision I regret.
