The pinnacle of our outside linings is now made from 100% recycled materials. In addition to its outstanding flexibility, it doesn't absorb water instead, it disperses it through tiny channels. This enhances water evaporation and shortens drying time.

This outside lining is sourced from nylon waste, but the best thing is that its stretch properties are just as good as conventional linings.

Our premium lining provides both heat retention and optimal stretch. The high-pile fabric effectively traps air, ensuring cozy warmth and insulation, while the vertically aligned channel structure swiftly transports moisture away, leaving your suit dry after your break between sessions.

The Hot Stuff 2.0 comes with a plushier feel due to larger loops that trap more air for heat insulation. It is the stretchiest thermo lining in ION‘s entire range.

A silky interior lining ensures a comfortable feel against bare skin. Despite its cozy appearance, it proves to be incredibly durable with its superb flexibility.
