Frequently Asked Questions
What is the difference between the 1mm and 1.5mm versions?
The 1.5mm L/S Top provides slightly more thermal protection than the 1mm S/S Top, making it a better choice for water temperatures between 20°C and 26°C. The long sleeves also add extra UV protection and rash coverage on the arms.
Can I use this as a base layer under a wetsuit?
Yes. The Reactor 2 1.5mm L/S Top works well as a base layer under a spring suit or winter wetsuit for added warmth. The slim UltraFlex construction minimises bulk when layering.
How should this top fit?
Neoprene tops should fit snugly to be effective. A well-fitting top should feel slightly tight when dry and comfortable when wet, with no excessive material bunching at the shoulders or underarms.
Care & Maintenance
Rinse with fresh water after every session. Dry inside out in the shade. Do not tumble dry, bleach, iron or dry clean. Store loosely in a cool, dry place away from direct sunlight and heat sources.
