Foot Box Too Small

I returned this product before using it

Therma-Rest makes great products and the quality and workmanship was there with this sleeping bag liner, however unless you really want to feel like a wrapped mummy from the knees down beware the manufacturer's sizing for the foot box. Way too small for comfort and movement. Better off with a rectangular liner that matches close your mummy bag dimensions.
