Tank really "LOVE'S" his...We hunt some pretty icey water's and the neopream[sp?] really help's. he's had to make some long retrieve's around 100 yd's and back, so I know the floatation devise help's him save some energy...he's also a very hard charging dog and was alway's worried about him jumping high in either the brush or water without know what he was going to land on so the chest protector give's me some relief..
