Zone3 Xfinity Renew Swimwear Review 2026 — Sustainable Performance
Zone3’s Xfinity Renew swimwear collection brings together two priorities that matter to performance swimmers and eco-conscious triathletes: race-quality speed and sustainable materials. Made from 100% recycled polyester sourced from post-consumer plastic bottles, the Xfinity Renew fabric is chlorine-proof, sunscreen-resistant, and built to outlast standard training suits across a full season of regular pool and open water use.
What to Look For
Triathlon swimwear needs to survive repeated pool sessions, open water exposure, and the mechanical stress of wetsuit use. Chlorine and salt degrade cheap fabrics rapidly — the Xfinity Renew’s chlorine-proof construction directly addresses this, extending lifespan significantly over standard polyester suits used in the same conditions.
Key Features to Consider
- Xfinity Renew recycled fabric — 100% recycled polyester from post-consumer plastic bottles. Chlorine-proof and sunscreen-resistant for extended lifespan.
- Open water and pool performance — Cut for training use with a secure waistband that stays in place under a wetsuit during long sessions.
- Colour retention — Unlike basic polyester suits that fade within 30–40 pool sessions, Xfinity Renew retains colour significantly longer.
- Flatlock seams — Reduces chafe during extended swims and under wetsuit use, important for athletes who train daily.
- Available in jammer and trunk styles — The jammer cut is recommended for competitive triathletes for lower drag and a more secure fit.
Our Top Picks
Best Overall: Zone3 Men’s Xfinity Renew OWS Jammer
The Xfinity Renew jammer is the standout choice for male triathletes doing regular pool and open water training. The competitive mid-thigh cut minimises drag, and the chlorine-proof construction survives a full season of 4–5 pool sessions per week without the fade, stretch, and deterioration that makes cheap jammers a false economy. It sits flat and comfortable under a wetsuit for open water sessions.
Best Mid-Range: Speedo Endurance+ Jammer
Speedo’s Endurance+ range is the gold standard for chlorine-resistant training swimwear at a mid-range price. Made from 100% Endurance+ polyester, these jammers are designed specifically for high-frequency training and offer a reliable, consistent fit across multiple seasons.
Best Budget: Arena Training Jammer
Arena’s training jammer range offers genuine durability and a performance-oriented cut at an accessible price point. Look for the Core Soft range for best value — these will last a full season of regular training without significant degradation.
Buying Tips
- Competitive jammers should fit tightly — snug at the waist and thighs with no sagging when dry. They stretch when wet.
- If wearing under a wetsuit, avoid loose boardshort-style trunks — they bunch and chafe under neoprene during long sessions.
- Buy at least two training suits and rotate them — rinsing and drying between sessions extends the life of both significantly.
Care and Maintenance
Rinse in cold fresh water immediately after every swim to remove chlorine and salt residue. Machine wash in cold water on a delicate cycle without fabric softener, which breaks down the chlorine-resistant coating. Air dry flat — tumble drying destroys the elastane fibres. Hang flat rather than on a peg to preserve the waistband shape over time.
