NIKE HYDRASTRONG SPRAYFETTI PRINT JAMMER
Black
Streamlined to reduce drag and look good while doing it.
The Nike HydraStrong Sprayfetti Print Jammer in Black provides long-lasting durability, swim after swim. Fully lined for better fit, comfort, and a secure feel, it keeps you focused on hitting your personal best. Flatlock seams help reduce chafing, so nothing gets between you and the wall. Built for every session, session after session.
3 Key Features
HydraStrong Durability
Nike HydraStrong fabric is engineered to hold its shape and colour across countless pool sessions. It resists the breakdown caused by chlorine exposure, keeping the jammer performing as well on your hundredth swim as your first. This is a training tool built to last.
Fully Lined Fit
The full lining delivers a secure, comfortable feel that moves with you through every stroke and turn. It eliminates unwanted movement inside the jammer, so the fit stays consistent from warm-up to the final length. You can trust it to stay exactly where it should.
Chafe-Free Construction
Flatlock seams sit flush against the skin to minimise friction during long training sets. Combined with an interior drawcord for a dialled-in waistband fit, the jammer stays put without irritating. Every detail is focused on keeping you comfortable and in the water longer.

Frequently Asked Questions
How does the HydraStrong fabric hold up to regular pool use?
Nike HydraStrong is specifically designed for durability in chlorinated water. It resists the fabric breakdown that standard swimwear can suffer from, making this jammer a strong choice for swimmers who train frequently.
How do I find the right size in this jammer?
Nike jammers are sized to provide a snug, supportive fit, and the interior drawcord allows some fine adjustment at the waist. For detailed measurements and guidance, please refer to our Nike Mens Swimwear Size Guide.
Is this jammer suitable for competitive racing?
This is a training jammer rather than a competition race suit. It is built for durability and comfort over a long training life, making it ideal for regular pool sessions and club training rather than race-day use.
Will the Sprayfetti print fade over time?
The HydraStrong fabric is engineered to resist colour fade caused by chlorine exposure. Rinsing the jammer in clean water after each session will help maintain the print and extend the life of the garment. See our full product aftercare guide for full guidance.
Care Instructions
- Rinse immediately after every use in cool, non-chlorinated water
- Do not leave the wet suit in a bag for extended periods
- Leave to dry naturally avoiding sunlight
- Hand wash only with a detergent suitable for delicate fabrics
- Air dry by hanging away from direct heat sources
- Do not machine wash, tumble dry, wring, iron or dry-clean

Why Buy from Allens Swimwear?
A Family Business Built on Swimming Since 1976
Allens Swimwear is a family-run business founded in 1976 by Dennis Allen and his daughter Linda Beal. It started from a genuine need. “With 2 swimmers in the family it was often difficult to find the right kit, so dad and I took the plunge and started selling to local swimmers at our local pool in Kingsbury out of a suitcase and we’ve never looked back.” Today, Linda, her husband Richard, and three of their children Danny, Will and Jenna still run the business together. The suitcase may be long gone, but the founding principle of helping swimmers get the right kit remains exactly the same.

Size chart
This size guide covers Nike Men's Swimwear. Nike splits its men's swimwear into two distinct categories: Performance Training — high-compression briefs, jammers, and square legs built for lap swimming — and Casual Lifestyle — loose-fitting volley shorts and boardshorts designed for poolside and beach wear. Choosing between them depends on whether you are tracking lap times or lounging poolside.
Select your size using your waist (A) and hip (B) measurements. All measurements are body measurements taken directly against the skin.

Fit Notes — Nike Men's Swimwear
- Use your waist measurement (A) as the primary guide — this is the most reliable indicator of fit across both training and casual styles.
- For performance training styles (briefs, jammers, square legs) — the suit should feel compressive and snug with no sagging or wrinkling. If between sizes, size down for a tighter fit or up for more comfort.
- For casual lifestyle styles (volley shorts, boardshorts) — the waistband should sit comfortably at the natural waist. The fit is intentionally loose through the leg.
- If your waist and hip measurements suggest different sizes, size for the waist on training suits and for the hip on casual shorts for the most comfortable fit.
- Nike's HydraStrong fabric (used in training styles) resists chlorine, sun fade, and loss of stretch over time — rinse in cold fresh water after every pool session.
- Nike's casual lifestyle shorts use quick-drying woven polyester with built-in mesh briefs and deep side pockets with drainage — not suitable for competitive swimming.

Frequently Asked Questions — Nike Men's Swimwear
Measure your waist (A) and hips (B) using a soft tape measure taken directly against your skin. Use your waist measurement as the primary guide and compare to the sizing table above. If your measurements fall between sizes, speak to a member of staff at Allens who will be happy to advise.
Nike performance training swimwear — briefs, jammers, and square legs — uses HydraStrong polyester/PBT fabric with a skin-tight, compressive fit and zero pockets to eliminate drag. Nike casual lifestyle swimwear — volley shorts and boardshorts — uses quick-drying woven polyester with a loose fit, built-in mesh briefs, and deep side pockets. Choose training styles for lap swimming and casual styles for poolside or beach use.
If your measurements fall between two sizes, the best choice depends on the style. For training suits, size down for a tighter, more performance-oriented fit or up for more comfort during longer sessions. For casual shorts, size for comfort at the waist. Speak to a member of staff at Allens who will be happy to advise based on the specific style you are considering.
Nike casual lifestyle shorts are not designed for lap swimming. The loose fit and woven polyester fabric create drag in the water and the deep pockets fill with water during swimming. For pool training, choose a Nike performance training style — briefs, jammers, or square legs — which are specifically engineered to minimise drag and withstand regular chlorine exposure.
Nike HydraStrong is a performance fabric made from a polyester and PBT blend specifically engineered for frequent pool use. It resists chlorine degradation, sun fading, and loss of stretch over time — meaning the suit retains its shape and coverage session after session. HydraStrong is used across Nike's training swimwear range including briefs, jammers, and square legs.
Briefs offer the least resistance and maximum freedom of movement — popular with competitive swimmers and triathletes. Jammers extend to just above the knee and provide light muscular compression and coverage — a popular choice for training. Square legs sit mid-thigh and offer a balance between coverage and mobility. All three use the same sizing — choose based on your personal preference and the type of training you do.
For training styles: rinse in cold fresh water immediately after every pool session to remove chlorine. Hand wash or machine wash on a gentle cycle at 30°C. Do not tumble dry, iron, or dry-clean. Dry flat away from direct sunlight. For casual styles: follow the care label on the individual garment — most can be machine washed. Avoid fabric softeners on training styles as they reduce the fabric's performance properties.
Nike training swimwear is designed for a close, compressive fit — it will feel tighter than everyday clothing at the same waist measurement. The sizing table above uses body measurements, so comparing your actual waist measurement to the table will give the most accurate result. If you prefer a less compressive feel, consider sizing up. For casual styles, the fit is intentionally loose and relaxed. Speak to a member of staff at Allens if you are unsure.
