I have both the Sapper and the 2 piece full suit from Allpredatorcalls.com. I love mine, I got the Sapper in largest size to were over coveralls in winter. The other for warm weather and over T shirt. I like the light weight, cool comfortable, easy on and off features. Besides being well made, you can wad it up and stick in large coat pocket. I go calling with my 11 yr. old Grandson and he wears the top to my full suit and then we both have Sappers. I highly recommend these kill suits.
