Erniewrote a review of Sierra Designs Down Bootie - Men's on February 18, 2003
Tried these in the Whites in winter, using them while tenting in snow. Great to let the boots rest (and feet flex) while in a warm bootie. These have grips so you can walk outdoors (on somewhat level ground), get water, go to the head at night, etc. Great for tenting or any situation where you don't want to keep lacing up then taking off ice-caked boots. Very light, worth the weight and price.
