TWO-PIECE SWIMSUITS FAQS

Are there two-piece swimsuits designed specifically for active water sports?

Yes, technical two piece swimsuits are specifically constructed to remain secure and supportive during intensive water activities like surfing, stand-up paddleboarding, and open-water swimming. Standard fashion swimwear often lacks the structural reinforcement needed for wave impact or repetitive arm rotation. ... Athletic designs utilize wide elastic under-bust bands, reinforced cross-back straps, and stay-put waistbands to ensure your suit stays firmly in place regardless of movement. The technical reason behind choosing dedicated athletic swimwear is hydrodynamics and security: high-tension elastane fabrics combined with flatlock seams minimize drag and prevent skin chafing during repetitive strokes. Many active swimmers choose models from Decathlon because they incorporate chlorine and salt-resistant textiles that maintain their stretch and elasticity over extended exposure to pool water and ocean spray. Whether you are catching waves on the Irish coast or training in a local pool, exploring our wider range of women's swimwear helps you select the exact level of support, coverage, and flexibility required for your favourite aquatic discipline.

Pro-tip: When selecting a top for high-impact water sports, opt for crossover X-back or racerback straps, which distribute pressure evenly across the upper back and prevent shoulder straps from slipping during vigorous paddling.

How do I choose between a two piece swimsuit with shorts and a classic cut?

Choosing between a two piece swimsuit with shorts and a traditional swimsuit cut comes down to your personal preference for coverage, thermal comfort, and activity type. A two-piece set featuring swim shorts or a shorty bottom provides enhanced coverage across the hips and upper thighs, making it an excellent choice for board sports, beach volleyball, or active outdoor swimming in variable Irish weather. The technical "why" behind shorts-style bottoms is skin protection and friction reduction: the extended leg length prevents board chafing against the inner thighs while offering complete peace of mind during dynamic movements. Conversely, if your focus is uninhibited leg movement for lap swimming or sunbathing, traditional bikinis offer maximum freedom around the hip joints. Both options deliver excellent comfort, but shorts provide that extra security and protection when active on the water.

Pro-tip: Look for swim shorts with an internal drawstring waistband; tightening the drawcord before diving or taking on surf waves prevents the waistband from riding down upon sudden impact with the water.

What are the advantages of sporty two piece swimsuits compared to one-piece suits?

Sporty two piece swimsuits offer exceptional versatility and fit customization that single-piece designs cannot easily match. One of the primary advantages of a two-piece ensemble is the ability to mix and match top and bottom sizes independently. This is particularly beneficial for athletes who require a larger top for bust support or a smaller bottom for streamlined hydrodynamics, eliminating the fit compromises often forced by fixed torso lengths in one-piece swimsuits. From a technical standpoint, two-piece active wear allows greater torso elongation and rotational freedom through the core during swimming strokes or paddling. Additionally, two-piece sets are substantially easier to change out of post-swim and dry faster when laid out flat, making them highly practical for day trips along the coastline or multi-sport training days.
