Elastic band around the ankle is too tight, restricting circulation
Sub-premium 450-fill down (not quite as warm or as packable as premium down)
This is a down camp bootie of average quality but comes at a very good price. It has very good packability, and we found it best for cool weather (above freezing). The too-tight elastic band around the ankle was a noticeable flaw that was easily remedied with a pair of scissors.
Camp booties don’t have to do much—they’re designed to keep your feet warm, and allow you to shuffle around outside a tent, or in a yurt, in comfort without taking up a lot of space in your pack.
Sierra Designs Down Packable Bootie covers the basics well. They were ideally suited for cool (not cold) nights and dry weather. The 450-fill down is not top-quality, but it’s sufficient for temps down to about freezing, and the compressibility is still very good. You may want to invest in a heartier pair if you plan on camping in full winter conditions.
Although there is a “non-skid” nylon sole (just a thin piece of abrasion-resistant nylon, without much structure), the sole is not waterproof, and some wetness seeped through the seams after walking for a bit in the snow. On the plus side, these booties rise up over the ankle for extra warmth, with a comfy fleece cuff, and come in fun, girly hues (I like their powder blue “sky”). There is also a heel pull-tab which comes in pretty handy. The major downside to this model is the elastic band around the ankle to secure them onto your foot: it was so tight I had to cut mine after my feet lost circulation while sleeping.
