Santi has used the best materials and available technologies for the BZ400X undersuit.

The Thinsulate™ BZ400 Insulation, recommended by 3M, provides effective insulation, resistance to moisture and breathability. It is one of the best insulation which can be used in undersuits.

It is compressed, does not take up too much space under the drysuit, and does not restrict the diver’s movement.  It has a net layer, which makes the BZ400X even more durable and practically indestructible.

Very few divers require a totally made to measure suit due to the wide range of standard sizes available from Santi Diving. With this in mind, Santi offers a free of charge Made-to-Fit service to any standard Santi BZ400X Undersuit ordered, sculpting standard suits to a divers' measurements.

With your BZ400X Undersuit order, you can request up to 4 changes (ranging from 2 to 5 cm) to any of the standard size measurements listed under chest, inner arm, biceps, forearm, waist, hips, inner leg, thigh, calf or body trunk on the Santi size chart.

If you would require more than 4 changes to make your suit perfect, you can add two more changes for a small additional charge.
