I had two of these made for a flight I had to do in the awesome WI weather. With the Felt fabric that was left over, I had my 6 year old..just kidding...the adult person that made the two for me make 16 extras. The insulated/warmer has two pockets for the toe warmers you can buy at any store to be placed inside. If its not that cold out the insulator can work with out the warmers in the pockets, I guess that would be your call on how cold it is outside for your flight. The pictures show a white stitch. This is just to show where the stitching is made for the warmer. I used sticky back Velcro, not the commercial stuff, the regular Velcro to make sure its stays put. The insulator will not have any Velcro in-case you wanted to choose which type you wanted. See the pics for what they look like. I only have 16 of them... 12 bucks each shipped inside the 48...then they are gone.. Paypal or I can invoice by my Square and you can pay via any credit card... Let me know..
