Custom Autumn 300 Dry Suit Undergarment

Custom Autumn 300 is a medium-density undersuit, 300 g/m², for seasonal diving in water from +5°C to +10°C. The name reflects its purpose: autumn and spring, transitional conditions where a light undersuit isn’t enough and a heavy one is overkill. A good choice for regular dives in moderately cold water.

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.
