Staying warm on stand with chemical warmers, are they most effective?

The chemical warmers work great, and they're cheap. But, if I'm on the ground, it's the Heater Body Suit.

Several years ago I started using Thermacare Back Wraps for all day hunting in extreme cold.  The NAME BRAND ones last a full 12 hours.  Do not get the generics, they only last a couple of hours.  One of these wrapped around the lower back will help keep your kidneys and lower back area nice and toasty.  I put it on over my first layer as they are too hot to have right against your skin.

I have expensive battery operated heated socks and a vest, but quite honestly they aren't worth the money in my opinion.  The battery charge just doesn't last very long...a couple hours on medium or high.  If just hunting a morning or evening sit, the few hours they last is OK, but no good if you're going to be out all day.

Mine yesterday lasted 2 hours but they were old.  They are a necessity for cold sits. Along with the kidneys I find some near the femoral arteries help a lot.

I have used 6-12 at a time. The Hot Hands brand works much better than the other major brand. I purchased a whole box of the wrong brand and will probably throw them away. I can't shoot when I'm cold. My hand won't release the string.

After cooling off in the stand. I put hand warmers all over my body. Try to use places that can transfer heat best. You want the core warm but also keep blood vessels open to hands and feet. put some in the top of your socks. (you could use the boot kind but I don't want to take off my boots) Put one in your cuff right at your wrist. You would be surprised how warm your hands and feet stay with just that.
Also I put them in m armpits,  in my neck gator, and under my hat. I put one in my jacket pocket for the shooting hand.

I am out right now in NH. 6 inche's of fresh snow on the ground, 28 degrees . Not as cold as two days ago, but for this four hour sit I have 8 of them. One on each side of my lower back, one in each pocket, one toe warmer for each foot and one on the soles of each foot. Absolutely makes a difference
