Back on Track Wraps ?? Teach Me Please!!

[sweetpea]

I am considering buying the pillows or no bow Back on track wraps but before I do I have questions for those that use them.

Would they be good for at shows for legs overnight after jumping?? I usually poultice .

I have heard they can be warm-- is it like sweat their leg warm?????

I guess I don't understand them so please help me.

Also has anyone used the saddle pad??? Or three quarter sheet??

Thanks so much!
