Product Description


This thermal, long-sleeved top is designed for wear in water. It will keep you warm and cosy during swimming sessions or outdoor water activities.

The super soft, brushed fleece inner and four-way stretchy fabric make this top ultra comfortable. It is also close-fitting to prevent any extra drag when worn in water.

It is ideal for use as a base layer under wetsuits for water sports but can also be worn under regular clothing to keep you warm in chilly outdoor environments. The Thermaswim range is made from a moisture-wicking fabric that evaporates sweat, helping keep you dry and comfortable when worn under clothing.

The Thermaswim top can be worn underneath or on top of regular swimwear, depending on personal preference.

Thermal shorts are also available.
