🏊 Guide for Swimsuits in Iceland – Lagoon-Ready Bathing Suits: Arena Swimwear

Planning to swim in Iceland? If you're looking for swimsuits in Iceland — whether for relaxing in the Blue Lagoon, relaxing in Reykjadalur’s natural hot springs, or doing laps at Laugardalslaug in Reykjavík  - having the right swimwear is essential. If you plan on visting Iceland's swimming pools  it's essential to choose bathing suits that can handle Iceland’s unique conditions, with a mix of geothormal water and chlorine. Because from intense chlorine exposure to geothermal heat and saltwater, not all swimwear is created equal.

Arena offers a wide range of high-quality, chlorine-resistant swimsuits ideal for Iceland’s unique mix of geothermal pools, icy seas, and cozy hot tubs.
At Ludus.is, we specialize in Arena swimwear — a brand trusted by Olympic swimmers and Icelandic locals alike. In this guide, you’ll learn how different swimsuit materials perform, which Arena collections fit your needs, and where to buy the best lagoon-ready swimsuits in Reykjavík or online.
This guide breaks down Arena’s collections to help you choose the best materials and styles for Icelandic pools, spas, and adventures — from thermal lagoons to the local sundlaugar (swimming pools) found in every town.

🧵 Fabric Basics: What You Need to Know

Swimwear in Iceland needs to stand up to more than just wear and tear — it must handle frequent dips in warm, chlorinated pools, natural hot springs, and the salty sea. Chlorine, especially in public pools like Laugardalslaug, Vesturbæjarlaug, and Sundlaug Kópavogs, can quickly break down fibers like elastane, causing swimsuits to fade, stretch, and wear out.

Swimwear materials vary significantly in how well they tolerate chlorine — and the trade-off often lies between comfort and durability. Chlorine aggressively breaks down fibers like elastane and nylon, leading to sagging, fading, and a shortened lifespan.

👉 According to Coral Reef Swim, it’s essential to choose fabrics that resist chlorine and hold up to long-term pool use.

Here’s a breakdown of common materials — ranked from most to least chlorine-resistant:

Key takeaways:

• Polyester & PBT are ideal for Icelandic swimming pools — long-lasting and chlorine-proof.

• Nylon blends are softer and stretchier but break down faster - better for occasional lagoon or hot spring visits.

• Lycra Xtra Life improves the chlorine resistance of elastane significantly and suits multi-use travelers who’ll dip into both pools and spas.

• Avoid suits with high elastane content for regular use in hot or chlorinated water — they break down faster, especially in Iceland’s naturally warm hot pots.
