IceArmor is not flotation,but my Boy O Bouy,is just wore out,knees shot,and all the insulaition in the arms is down at the cuffs, but I really like the IceAromor,easier to get around,less bulky,more comfy,and much warmer. I only use it for ice fishing and in the early season i wear my boy o bouy, just in case,I dont want the helicoper looking for me
