REI Down Booties
Here's what other sites are saying:
Our REI Down booties provide excellent warmth, compressibility and comfort around the cabin, in the tent or when you're just lounging about home on a Sunday morning. 450-fill-power duck down insulation compresses easily for packing. Polyester shells feature a Durable Water Repellent to fend off moisture and light rain. Soft polyester fleece linings are heaven on bare feet; elasticized instep straps keep booties secure. EVA midsoles help REI Down booties provide cushioning underfoot; polyester soles sport polyurethane beads for enhanced traction.
