Pumping in the winter

I'm also in Alberta, where the weather can get pretty cold. In the winter I wear my pump clipped in the middle of my bra, and in the summer I wear it in a Spibelt around my waist. I was really concerned the cold would affect the mechanism of the pump or freeze my insulin because I am outdoors alot. A guy could wear the pump in a Spibelt & under the winter jacket as another option.
I was camping in the fall and my tucked my glucometer under my pillow at night, but it woundn't work becuase it was too cold in the morning. Was fine after I warmed it up though. Next time I kept it in my clothes and against my body.
