Within the Boneswimmer range, the Pinup and Ibiza models share the same sporty vocation and the same quality of materials, but differ in cut and intended use. The Pinup stands out for its exposed sides, which enhance the silhouette and offer greater freedom of movement; the Ibiza , on the other hand, features a more closed cut, with side coverage that makes it more compact and controlled in shape.
Both are made of 100% PBT , a chlorine-resistant and non-deformable fabric, but the Pinup emphasizes the absence of elastane, ensuring extreme durability and consistent performance even with intensive use.
The Pinup is therefore designed for those looking for a technical and durable swimsuit, while the Ibiza combines sporty performance and greater adaptability to shapes.

In the Boneswimmer men's catalog, the H2Otto and UCLA models represent two distinct approaches to training swimsuits, differentiated by their cut. H2Otto is a swimsuit with brief/racer characteristics, designed for those who prioritize agility, essentiality and pure performance: it has a reduced side width (about 8 cm) and includes a drawstring waist adjustment, as well as double front and back lining to ensure coverage. UCLA is a trunk/boxer style with slightly more coverage: it also has a front lining and is positioned as a technical men's swimsuit with a balance between coverage and agility. Made from chlorine-resistant PBT fabric , without elastane, to ensure durability and stability even after intensive use, Boneswimmer H2Otto is the ideal model for those looking for a minimalist swimsuit for racing or intense training, with an extremely essential cut and maximum focus on performance, while UCLA offers a more versatile and covering version, with a balance between comfort, coverage and style.

On the Boneswimmer website, the size guide explains that training swimsuits are made of 100% PBT , a technical fabric without elastane: highly resistant to chlorine and retains its shape, but with a more rigid fit. They should fit like a second skin, feeling tight when dry but comfortable in the water; those who prefer more comfort can choose a larger size. Swimsuits, on the other hand, contain elastic and are easier to put on, but require care when washing and drying.
For women , the Pinup and Ibiza models run true to size, with the option to go up a size for greater comfort: the Pinup is more high-cut and open at the hips, the Ibiza is more closed and supportive. For men , the H2Otto and UCLA run true to size: the former is more basic and close-fitting, the latter offers more coverage and a balanced fit. Both have an adjustable drawstring waist.
In junior models, the fit is smaller: the 12-year-old corresponds to a size 38, the 10-year-old to a size 36, and the 8-year-old to a size 34. When these measurements become tight, Boneswimmer recommends switching to women's sizes. In general, the brand favors a sporty, snug, and durable fit, consistent with its philosophy of high-performance technical swimsuits.

Boneswimmer training suits are designed for intensive use in the pool and made of 100% PBT (polybutylene terephthalate) , a technical material derived from sports that guarantees exceptional resistance to chlorine, sunlight, and wear over time . These elastane-free fabrics are therefore not subject to sagging or deformation, maintaining their compression and fit over the body over time. The fit is deliberately technical and supportive: a Boneswimmer suit must fit like a second skin to ensure support and stability in the water, minimizing friction and improving glide.
The beachwear , on the other hand, is designed for more recreational use: it contains a percentage of elasticity that facilitates fit and comfort even when dry. Less compressive, but equally meticulously detailed, these models are ideal for those who want the sporty design and reliability of Boneswimmer even outside the pool.
The main difference, therefore, lies in the intended use: training models are designed for performance and durability, while beach models focus on comfort and versatility.
This is one of the features that distinguishes Boneswimmer from many other brands: durability over time, even when exposed to chlorine. All training suits are made of 100% PBT , a high-quality synthetic fiber resistant to chlorine, UV rays, and abrasion. This elastane-free material doesn't lose its shape over time or fade, even after hundreds of hours of training in the pool. It therefore maintains our vibrant, unconventional, and colorful graphics intact.
The advantage of PBT is twofold: on the one hand, it ensures exceptional durability , on the other, it maintains constant compression of the fabric, preventing the suit from stretching or losing support. This is why many competitive swimmers choose Boneswimmer for daily training: because it offers a virtually indestructible suit, capable of withstanding even the most extreme conditions without compromising comfort or performance.
Absolutely. Boneswimmer offers a line dedicated to customization , the Custom Edition , which allows you to create unique swimsuits in design, graphics, and colors, while maintaining the same technical quality as the standard models. Each customized swimsuit is made with the same chlorine-resistant PBT fabric and handcrafted in Italy, with particular attention to printing and color rendering.
Customization is ideal for swim teams, sports clubs, masters teams, or individual athletes who want to stand out with a distinctive technical swimsuit. We also serve spas and wellness centers , resorts , and holiday villages , producing and customizing swimwear and beach and pool accessories (swimming caps, towels, bathrobes, ponchos, beauty cases, bags, backpacks, and more).
You can insert logos, names, graphics or exclusive patterns, creating a unique product, but with the same qualities as the professional Boneswimmer lines.
The Custom Edition service enhances both the brand's identity and the functionality of the swimsuit or accessory, combining aesthetics and technology in a tailor-made product. Find out how to create your own custom swimsuit .
A technical suit like Boneswimmer's deserves the same care you'd give a professional sports piece of equipment. After each use, it's important to rinse the suit in cold water to remove any chlorine or salt residue and let it dry naturally , away from heat sources or direct light. Washing in a washing machine, dryer, or using harsh detergents, which could alter the properties of the PBT fiber, is strongly discouraged.
Despite the fabric's extraordinary durability, the swimsuit's longevity also depends on daily care: proper maintenance ensures consistently vibrant colors and a lasting fit. By following these simple rules, a Boneswimmer swimsuit can maintain its shape and performance even after years of intensive training, proving to be a lasting investment for those who enjoy the pool with consistency and passion.
All Boneswimmer swimsuits are designed and made in Italy , following a philosophy that combines craftsmanship, technology, and a passion for swimming. The company was born from the direct experience of athletes and technicians in the sector, with the goal of creating training swimsuits that can withstand long daily sessions in the water without losing shape or color.
Artisanal production allows for consistent quality control on each garment: stitching, printing, and finishing are all done by hand to ensure precision, fit, and durability. Boneswimmer stands out for its choice of sustainable materials and exclusive graphics, the result of recognizable and distinctive Italian design.
Each swimsuit is designed as a high-performance training tool, but also as a sign of identity and belonging for those who live swimming with passion and consistency.
