depending on the temperatures outside(cuz ur walking) im sure you can use a small rubbermaid container of some sort, i usually transport my BP's in pillow cases, they cant escape(if u tie the top in a knot) its relatively warm and if i feel its not warm enough ill put the pillow case under my shirt or sweater
Cheers!
