Custom Line 500-600 Dry Suit Undergarment

Custom Line 500-600 is a heavy undersuit for cold and ice water with a density of 500–600 g/m². Built for dives at temperatures from -2°C to +4°C: under-ice diving, technical tasks in freezing water, and long work at depth. Despite its density, the material stays elastic and doesn’t absorb moisture from condensation inside the suit.

Custom Master undersuits are made from synthetic fiber with a bulky weave — a material that retains heat even when compressed under dry suit pressure. Fits any dry suit regardless of manufacturer. Flat seams to avoid chafing, reinforced knees and elbows, elastic cuffs for easy donning.

The material doesn’t absorb moisture and ventilates well — critical when condensation forms inside the dry suit during a dive. The undersuit keeps its insulating properties even after repeated compression and washing.
