The Willis from Astral is a super slim PFD. The PFD has a number of features in common with the very popular green jacket.
This includes a buckle system that allows side entry into the PFD, a front throw bag storage compartment, and a deep front pocket. A knife attachment point and reflective detailing complete the front of the PFD.
The rear of the Willis is a no nonsense affair and has a very clean design.
One side of the Willis opens completely by the use of a couple of pretty good buckles. Adjustments includes 2 x side buckles each side plus the waist belt. The front floating panel can be adjusted by two straps on the lower portion of the panel. The fit of the Willis is pretty good and once all fastened up the PFD remains in place. The low profile of the Willis does mean that movement is not compromised in any way.
