Compression
A snug, supportive fit can help manage soft-tissue movement. Too much compression, however, can restrict movement or comfort.

THE ULTIMATE TECH SUIT GUIDE.
Everything UK swimmers, parents and coaches need to know about choosing, fitting, caring for and repairing competition racing suits.
Start here
Race ready starts with knowledge.
The most expensive racing suit isn't automatically the best one. The right suit combines correct sizing, comfortable compression, event suitability and careful handling. Use this guide to make informed decisions before your next competition.
01 / The essentialsSupport Fabric Design
What is a tech suit?
A tech suit is a specialist competition swimsuit designed with performance-focused materials and construction. Its features can include targeted compression, water-repellent fabric finishes and carefully engineered seams.
Hydrodynamics
Smooth materials and water-repellent finishes are intended to help manage drag through the water.
Movement
Different back, waist, hip and leg constructions feel different in the water. Fit matters more than marketing claims.
A tech suit does not replace technique, fitness or preparation. No suit guarantees a personal best.
02 / Race compliance
Know the competition rules.
For pool racing, World Aquatics rules place limits on swimsuit coverage and construction. Events may also impose additional approval requirements.
| Suit category | General pool-racing coverage limits |
|---|---|
| Men's suits | Not above the navel or below the knee. |
| Women's suits | Must not cover the neck, extend past the shoulders or below the knee. |
| All suits | Must comply with the applicable event's material, construction and approval requirements. |
Always confirm the current rules for your specific meet and governing body. Do not assume that US age-group tech suit restrictions automatically apply in the UK. Check World Aquatics and your competition conditions before purchase.
03 / Choose with confidence
Which style is right for you?
Men's racing jammers
Consider waist height, hip movement, leg compression and comfort during starts and turns.
Women's open-back kneeskins
Often preferred by swimmers looking for freedom around the upper back and shoulders.
Women's closed-back kneeskins
Offer a different feel of coverage and support. Prioritise shoulder mobility and overall fit.
04 / Match your event
Think beyond the distance.
| Event | Useful features to assess |
|---|---|
| 50–100m freestyle | Secure fit and firm, manageable compression. |
| 200–1500m freestyle | Comfort, mobility and sustainable compression. |
| Breaststroke | Hip flexibility and unrestricted kick mechanics. |
| Butterfly | Shoulder mobility and core comfort. |
| Backstroke | Secure fit and comfortable movement. |
| Individual medley | Balanced flexibility across all four strokes. |
These are general considerations, not evidence that a particular suit guarantees better results in any event.
05 / Find your fit
Fit comes first.
Racing suits should feel noticeably tighter than training suits without causing pain, numbness, restricted breathing or unsafe pressure.
- Take accurate measurements using the specific manufacturer's guide.
- Check waist, hips and any other required dimensions.
- Do not automatically size down.
- Make sure shoulder and hip movement remain comfortable.
- Allow time to try the suit before race day.
NE fitting reminder
There is no universal size across all racing suit brands. A size that works in one model may not work in another.
Never force a suit that appears too small.
06 / Handle with care
How to put on a tech suit.
Start dry
Make sure your skin and suit are completely dry before fitting.
Remove jewellery
Check fingernails and remove anything that might snag delicate fabric.
Work gradually
Use the pads of your fingers and move the material a little at a time.
Check comfort
Even out the fabric, inspect seams and ensure breathing and movement are comfortable.
07 / Protect your investment
Care that helps your suit last.
✓ DO
- Follow the manufacturer's care label.
- Rinse gently in cool fresh water where advised.
- Air-dry away from direct heat.
- Store completely dry.
- Handle bonded seams carefully.
✕ DON'T
- Machine wash or tumble dry unless expressly permitted.
- Wring or twist the suit.
- Leave it damp in a swim bag.
- Pull aggressively on straps or seams.
- Use bleach or fabric conditioner.
When should a suit be replaced?
There is no fixed number of races. Look for loss of compression, excessive stretching, seam separation, peeling bonded areas or declining fabric performance. Some damage may be repairable.

WHY REPLACE WHEN YOU MAY BE ABLE TO REPAIR?
A damaged racing suit doesn't always mean the end of its useful life.
NE Sportswear offers a specialist tech suit repair service. We can assess suitable seam and fabric damage and advise whether a repair may be possible—helping swimmers make more of their investment and reduce unnecessary textile waste.
Not all damage is repairable. Repairs cannot guarantee restoration of original compression, hydrodynamic performance or competition approval.
09 / Your questions answered
Frequently asked questions.
Should I buy a tech suit one size smaller?
Not automatically. Use the manufacturer's measurements and size chart. A suit that is too small can restrict movement or become damaged.
Can I train in my tech suit?
Follow the manufacturer's guidance. Frequent training use may shorten the useful life of a premium racing suit.
Can a ripped racing suit be repaired?
Some damage can be repaired. Feasibility depends on the fabric, seam construction and location of the damage. NE Sportswear can assess suitable repairs.
Are tech suits suitable for breaststroke?
Yes. Pay particular attention to flexibility around the hips and freedom through the kick.
Are tech suits allowed for under-13 swimmers in the UK?
Rules depend on the relevant governing body and meet conditions. US age-group restrictions should not be assumed to apply automatically in the UK.
Does an expensive suit guarantee faster times?
No. Fit, individual preference, technique, training and race preparation all matter.
