Custom Line 250 Dry Suit Undergarment

Custom Line 250 is the lightest model in the Custom Master undersuit line, with a density of 250 g/m². Built for dives in relatively warm water from +10°C and above, and also as a base layer under a denser undersuit in cold weather. Ideal for travel — it takes up minimal space and weighs under 400 g.

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.
