RS 450K Drysuit


SKU: N/A Category:

The RS 450K is a trilaminate drysuit developed for divers that really care about the durability of their suit. All RS drysuits have been designed for demanding technical divers, wreck diving and cave diving. Only the best materials are chosen and this ensures that these suits are extremely resistant to tears, cuts and holes. The Italian design guarantees not only a fine aesthetic. It allows for a better air management, an excellent trim and buoyancy as well as maximum freedom of movement. RS drysuits are incredibly customizable. We offer 122 size combinations for men and 49 for women. They are made in Italy and Rofos makes tests on each suit to check its dryness before each shipment.

Each suit is custom made to your specifications.  Contact us to discuss sizing and various options.

Neck: standard neck is latex, but you can choose the neoprene neck seal and even choose the interchangeable neck (silicone or latex).

Wrists: standard cuff is latex, but you may prefer the interchangeable cuff, and mount the dry gloves later on.

Dry gloves: you can have the suit already with rings for dry gloves.

Boots: standard boots are neoprene, but you can choose the neoprene sock to be worn under a lace-up boot with a rigid technical lug sole (Rock Boot).

P-valve: The standard suits only have reinforcements for the p-valve, but you can choose to have the suit with a p-valve already fitted.
