Palm Arun Longsleeve - Mens

The Palm Arun Longsleeve - Mens is a lightweight thermal base layer for paddlers who want reliable comfort without adding unnecessary bulk. Worn next to the skin, it helps move moisture away from the body so you stay drier, warmer and more comfortable through longer sessions, cool starts and changeable UK conditions.

In Palm's layering line-up, the Arun sits on the practical, versatile side of things. It is lighter and simpler than a heavier fleece-style thermal, which makes it a strong choice under a wetsuit, drysuit, paddle jacket or waterproof shell. If you want a base layer that does its job quietly and lets the rest of your paddling kit work properly, this is exactly the kind of garment that makes sense.

Why choose the Palm Arun Longsleeve?

• Fast-wicking fabric helps keep you drier next to the skin, which is a big part of staying comfortable on the water.
• Low-bulk construction layers neatly under technical paddling clothing without feeling restrictive.
• Close-fitting cut works well for active paddlers who do not want loose fabric bunching up underneath outer layers.
• A sensible all-rounder for SUP, kayaking, canoeing and general watersports use across much of the year.

Range positioning

If you are comparing this with thicker thermals, the Arun is the option for breathability, ease of movement and simple layering. It is not supposed to replace a wetsuit or act as a standalone winter outer layer. Instead, it gives you a proper first layer that improves comfort and makes your overall clothing system more effective.

Helpful reading & buying advice

For practical UK layering advice, see our What to Wear Paddleboarding in the UK guide and our winter paddling layering article.

Is the Arun Longsleeve warm enough on its own for winter paddling?

It is best seen as your base layer rather than your full winter solution. It helps with moisture management and comfort, but in colder UK conditions most paddlers will wear it under a wetsuit, drysuit or protective outer layer.

Who is this top best suited to?

It suits paddlers who want a simple, close-fitting and low-bulk thermal layer for regular use. It is especially good if you want something more purpose-built than an ordinary sports top or cotton layer.

Can I wear it under a wetsuit or drysuit?

Yes. That is exactly where this sort of garment works best. The close fit and moisture-wicking fabric make it a very good next-to-skin layer under more protective paddling kit.

Should I buy this or go for a thicker thermal?

Choose the Arun if you want something lighter, simpler and easier to layer. Go thicker if you know you need more insulation from the garment itself and are not relying on outer layers to provide most of the warmth and weather protection.
