Frequently Asked Questions
What conditions is the 1mm S/S Top designed for?
The 1mm thickness is best suited for warm tropical water (above 24°C) where the primary need is rash and UV protection rather than thermal insulation. It is also effective as a light layering piece under a spring suit in transitional conditions.
What does the boardshort connector do?
The boardshort connector is a small clip or loop that attaches to the waistband of your boardshorts, keeping the top from riding up during paddling and duck-diving.
Can this top be worn for activities other than surfing?
Yes — the Reactor 2 1mm S/S Top works well for snorkelling, kayaking, paddleboarding and other water sports where a lightweight, flexible layer is beneficial.
Care & Maintenance
Rinse with fresh water after every session. Hang to dry in the shade, inside out. Do not tumble dry, bleach or dry clean. Avoid folding on the same crease repeatedly to prevent neoprene cracking. Store in a cool, dry place away from direct sunlight.
