The "Metis" is made with the same Toyota 4
layer fabric as Sandiline's drysuits. The elbows are reinforced with
cordura. The double wrist gaskets - latex underneath superstretch
neoprene - ensure that no water enters those cavities.
The neck is made with superstretch neoprene,
which feels comfortable and assures very good water tightness. It also
has an arm pocket where you can store small gadgets.
