In short: Private label swim rashguards are swim and surf tops a manufacturer makes to your specification and you sell under your own brand. Choose between an existing cut and your own developed style, know the fabric of every garment, approve a physical sample before bulk, and cut every reorder from the same approved pattern. Sportswear of Tomorrow makes private-label swim and surf rashguards in its own facility in Aiud, Romania, in Italian Carvico Vita PL fabric, from 1 piece on existing cuts and 2.5–4 weeks from artwork approval.
Swim and surf customers judge a rashguard by how it feels in the water, how it sits after hours of sun and wash cycles, and whether the next drop matches the first. For a brand founder or product manager, those details are decided with the manufacturer behind your label. This guide covers what private label swim rashguards involve, how fabric and development work, and what to agree before your first bulk order.
What are private label swim rashguards?
Private label swim rashguards are swim and surf tops produced by a manufacturer to your specification and sold under your brand name.
The manufacturer handles the pattern, fabric, printing, cutting and sewing. You own the brand, the range plan and the relationship with your customers. With sublimation, your logos, colours and graphics are dyed into the polyester fabric before the garment is cut and sewn, so the design can cover the whole garment, edge to edge.
Private label is different from buying blank rashguards and decorating them. A blank comes in someone else’s cut and fabric, with a print or transfer added on top. With private label, you choose the cut, the fabric and the full-surface design, and that is what makes a swim or surf range recognisably yours.
Why do swim and surf brands go private label?
Swim and surf brands go private label when they need a fit, fabric and look they control, without building a factory.
Typical reasons:
- Brand control. Your name, your colours and your artwork on every piece, with none of the manufacturer’s branding on the garment.
- A first drop you can sell through. On existing cuts you can start from 1 piece, test designs, then restock what sells.
- A signature fit later. Once you know what moves, you can develop your own style and keep that pattern for every reorder.
- Honest product pages. You get a written fabric composition and certification details you can put on labels and listings.
Sportswear of Tomorrow works with swim, surf, triathlon and water-sports apparel brands on private-label programmes and custom rashguards for brand ranges.
What fabric should a premium swim rashguard use?
A premium swim rashguard needs stretch and recovery, a print that is part of the fabric, and UV protection you can state clearly.
- Fabric. Water, sun and repeated washing put real load on a rashguard. At Sportswear of Tomorrow, every rashguard is made from Italian Carvico Vita PL: 78% recycled polyester and 22% elastane, 190 g/m², GRS-certified, OEKO-TEX-certified and rated UPF 50+. The same fabric is used for fight and swim rashguards; the cut is chosen per style.
- Print. With dye-sublimation the ink becomes part of the polyester fibre instead of sitting on top, so the design will not crack or peel the way a printed-on layer can after sessions and washes. It also allows full-colour designs edge to edge.
- Fit. The second drop should fit like the first. That only happens when the manufacturer keeps your approved pattern and cuts every restock from it.
Ask for the composition of every garment in writing. You will need it for your product pages and your labels.
Should you start on an existing cut or develop your own style?
Start on an existing cut if speed and a small first order matter most; develop your own style when fit is part of what you sell.
- Existing cut. Your design goes on a pattern the manufacturer already produces, so there is no development step. At Sportswear of Tomorrow you can order from 1 piece on existing cuts, which makes it a practical way to test designs, shoot a campaign or open a pre-order. See the rashguard category for the styles already in production.
- Your own style. The manufacturer develops a pattern from your tech pack, a technical drawing or a reference garment with measurements, and grades it into your size set. Development is usually a paid service per style. At Sportswear of Tomorrow, development is paid per style and part of the fee is refunded once the style reaches volume. New colourways or artwork on a developed style do not need a new development. See develop your own for how that process works.
Many swim and surf brands do both: they launch on an existing cut, learn what sells, then develop a signature long-sleeve or short-sleeve fit for the next drop.
How do sampling, tech packs and colour work?
You approve a physical sample of each new style before bulk, and you treat colour on fabric—not on screen—as the reference.
Before production, send a tech pack, a technical drawing or a physical rashguard whose fit you like, with measurements, plus logos in vector format (AI, EPS, SVG or PDF) and Pantone or colour codes. AI-generated images are fine as inspiration and for mood boards. A garment cannot be judged from images alone, so for production a manufacturer needs a real tech pack or a physical sample with measurements. If you do not have a tech pack yet, ask whether the manufacturer builds it with you as part of product development. At Sportswear of Tomorrow, we do.
Test the sample the way your customers will use it: swim or paddle in it, wash it, and check how it sits after a long session. Ask athletes in different sizes to try it, not only the founder. Compare colours with your Pantone references in daylight. Slight colour differences can occur because sublimation ink absorbs into the fabric, and screens show colour differently from fabric, so the approved physical sample is the reference. One honest limit of sublimation: a sublimated black is never quite as deep as a pre-dyed black fabric.
A sample costs far less than a bulk order in the wrong fit. At Sportswear of Tomorrow, 50% of a paid sample’s cost is credited against your bulk order of at least €2,000 ex VAT (shipping excluded).
Who owns the pattern, and how do reorders stay consistent?
Agree pattern ownership before development starts, and cut every reorder from the same approved pattern and colour files.
Your fit and your designs are part of your brand. Ask any manufacturer: is the approved pattern kept on file; are colour files stored with it; and is everything printed, cut and sewn in one facility? At Sportswear of Tomorrow, we keep your pattern on file for your reorders and you can buy it. We do not resell or reuse client-specific patterns. Printing, cutting and sewing all happen in our own facility in Aiud, Romania, with no partner factories. If you want an NDA before you share designs, send a short English NDA and we will review and sign it.
Volume discounts apply to larger orders. On existing cuts you can restock from 1 piece; for a developed style, the minimum is confirmed in your quote.
How long does it take from idea to first drop?
Production at Sportswear of Tomorrow takes 2.5–4 weeks from artwork approval on every order, bulk included, plus shipping; development and sampling for a new style come first.
Plan backwards from your launch date:
- Launch date (a season start, a retail delivery or your web shop drop)
- Minus shipping time
- Minus 2.5–4 weeks of production
- Minus time for the mockup, your changes and your artwork approval
- For a new style: minus development and sampling, planned per style in your quote
Delivery times vary week to week, so confirm the date with your manufacturer before you announce it to customers or retailers.
A practical first-drop approach:
- Launch two or three designs in a focused size run.
- Use pre-orders or a small first stock to learn what sells.
- Restock the winners from the same pattern and colour files instead of guessing a whole season ahead.
What can you claim on swim rashguard product pages?
Claim only what you can document: the garment’s composition, its certification and its tested properties.
Since 27 September 2026, the EU rules on environmental claims to consumers (Directive (EU) 2024/825) restrict generic environmental claims that cannot be substantiated, and environmental labels that are not based on a certification scheme or set up by public authorities. A specific claim is safer and more convincing. For a rashguard in Carvico Vita PL that could be: “78% recycled polyester, 22% elastane, GRS-certified fabric, UPF 50+.” Avoid a blanket recycled claim for a whole range when not every garment uses the same fabric, and ask your manufacturer which certification details you can keep in your compliance file.
None of the rashguards Sportswear of Tomorrow makes carry our branding. Your woven labels, hangtags and packaging are made by specialised label and packaging suppliers; you order and pay them directly and have them delivered to us.
