Wow I was surprised to see Costco selling some interesting gear of late.
Great deals on the hammocks as well.

Here are some links, not sure if your Costco has these things in stock, but online is selling them.

Sleeping bag system: Reminds me of the Exped Wallcreeper except this rating is to 14 degrees or so they say :)

I buy merino wool socks at Costco that I swear are identical to smartwool socks. They are equally as durable and comfortable. They cost $10 for 4 pairs of socks. They are their store brand (kirkland is it?)

Brian I discovered those last year too, got some for all of us. They were comfortable and well made. Who knows maybe Smartwool makes them for Kirkland :)

We use those Costco socks too- the brand is "Head."
