Harmony 2mm For Beginners

The Two Bare Feet Harmony 2mm wetsuit is designed for summer and cooler water swimming, providing year-round protection. With a lightweight 2mm CR superstretch neoprene construction, it offers warmth without sacrificing flexibility—ideal for beginners who need comfortable movement during open water swims, triathlon training, snorkeling, or paddleboarding. Flatlock seams and sealed hems reduce water entry and skin irritation, supporting longer sessions in varied UK conditions.
Arabella 2mm For Beginners

The Arabella 2mm wetsuit from Two Bare Feet mirrors the Harmony’s lightweight approach with similar warmth and flexibility. It features 2mm CR superstretch neoprene for thermal insulation and comfort across mixed UK conditions. The durable flatlock seams, combined with anti-chafing design, helps maintain comfort during extended sessions, making it suitable for new open water swimmers tackling longer distances or colder days.
Advanced Triathlon Wetsuit

The Synergy Triathlon Wetsuit 3/2mm Volution focuses on performance with a 3mm core buoyancy panel and 2mm sections at the legs and back, optimizing hydrodynamics for open water and triathlon training. It uses silicone-coated SyPrene for improved performance and an internal YKK zipper designed to minimize drag. The suit’s neck is designed to be soft and low-profile, reducing chafing and allowing a comfortable range of motion, especially beneficial for new entrants to longer swims or events.
SupaFlex 3/2 Full Length

The Two Bare Feet SupaFlex 3/2 full-length wetsuit offers a balanced blend of insulation and flexibility for UK summers, cooler seas, and transitional conditions. CR Superstretch coloured panels enhance flexibility and fit, while back-zip entry with a long pull cord simplifies on-and-off, especially when changing at the beach or alone. This make it a practical option for beginners seeking reliable coverage for longer sessions without bulk.
SupaFlex 3/2 XXL Full Length

The XXL variant of the SupaFlex 3/2 Full Length maintains the same performance features with a larger fit, suitable for swimmers who require a roomier chest and arm movement. The back zip entry with a long pull cord supports easy changes on the beach or at the water’s edge. This model is compatible with UK open-water training and casual paddling, keeping warmth without sacrificing mobility for beginners.
Buying Guide: Key Purchase Considerations
- Water temperature and seasonality: For UK conditions, 3/2mm wetsuits are versatile for spring, autumn and milder winter days, while 2mm options suit late spring to early autumn. Consider a back-zip design for easier on/off, especially if you swim alone.
- Fit and mobility: Mobility matters for open water swimming. Look for flexible panels, flatlock seams to reduce chafing, and neoprene with good stretch (CR or Superstretch). Ensure there’s a snug but not restrictive fit at shoulders and hips.
- Seams and durability: Flatlock seams reduce water entry and irritation. Sealed hems and reinforced cuffs help maintain warmth and prolong the suit’s life in frequent use.
- Ease of entry: Back-zip designs are common and easier for beginners. Front-zip or back-zip with long pull cords offer different balance between warmth and ease of removal.
- Buoyancy and core warmth: Some suits feature slightly thicker panels in core areas (3mm core buoyancy) for enhanced buoyancy and body position, which may benefit new swimmers who are still building technique.
- Brand availability and aftercare: Choose reputable brands with accessible UK sizing, straightforward return policies, and reliable customer service. Check for compatibility with accessories like wetsuit gloves or booties if you train in colder conditions.
- Weight and flexibility: For beginners, a lighter, flexible wetsuit can reduce fatigue and improve rhythm. Test for comfortable arm movement and shoulder flexibility to prevent restriction during stroke cycles.
- Maintenance: Rinse with fresh water after each session, dry inside-out away from direct heat, and store flat. This extends neoprene life and maintains flexibility for future training.
