SG Altimeter mitts 

Been eye balling these for a while. One question: The outer shell has a nice size gauntlet sized opening to go over your rain jacket or puffy. How does it compare to the insulated portion of the glove? Meaning, does the inner glove have a wide enough opening to go over a puffy jacket or will it bunch up the cuff/wrist portion of the jacket?

great review, however, the audio was bit low. I used the SG mittens this year during my hunting season and I they performed as expected.
