3 Key Features

Adjustable Tie Back Fit

The fully adjustable tie back design lets you dial in the exact level of support and coverage you need. Whether you prefer a looser feel for training or a snug fit for serious sessions, the tie back adapts to you. It is a simple but effective feature that makes a real difference in the pool.

Carvico Darwin PBT Fabric

Made from high-quality Carvico Darwin PBT, this suit offers excellent shape retention and a smooth, comfortable feel against the skin. PBT fibres are highly resistant to chlorine, meaning the fabric holds its colour and elasticity far longer than standard polyester suits. You get a reliable, long-lasting suit that performs session after session.

AK Essentials Value

The AK Essentials range was created to deliver top-quality swimwear at an accessible, affordable price point without compromising on the features that matter. UV protection, full lining, a high leg cut, and chlorine resistance come as standard. It is everything you need from a training suit, none of what you do not.

Frequently Asked Questions

QHow does the tie back adjustment work?

The back straps tie together rather than using a fixed clip or clasp, so you can loosen or tighten them to your preferred level of support before each session. Most swimmers simply tie them in a bow or double knot to keep them secure in the water.

QHow do I find my size in this suit?

AK suits follow standard swimwear sizing, but we recommend checking our AK Tie Backs Size Guide before ordering as fit can vary depending on body shape and personal preference.

QIs this suit suitable for daily pool training?

Yes. The Carvico Darwin PBT fabric is specifically chosen for its high chlorine resistance and shape retention, making it well suited to frequent pool use. Many swimmers find PBT suits outlast standard elastane suits significantly when training regularly.

QCan this suit be used at an outdoor pool?

Yes, the built-in UV protection makes it a practical choice for outdoor pool sessions as well as indoor swimming. Rinsing the suit in clean water after each swim will help preserve both the fabric and the colour over time. See 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.

Fit Notes — AK Tie Back Women's Swimsuit

The adjustable tie back allows you to customise the fit across the shoulders — adjust the ties so the suit sits flat with no pulling or gaping at the back.
The suit should feel snug but comfortable — it should hold its shape against the body without restricting movement or breathing.
The high leg cut should sit comfortably at the hip with no pinching or riding up during swimming.
The Carvico Darwin PBT fabric is highly chlorine resistant and retains its shape over time — it will not sag or lose its elasticity with regular use.
The suit is fully lined for comfort and opacity — check that the lining lies flat with no bunching when the suit is on.
The built-in UV protection helps shield the skin during outdoor training and open water swimming.
Rinse in cold fresh water after every use. Hand wash gently if needed. Do not machine wash, tumble dry, iron, or bleach. Dry flat away from direct sunlight.

Frequently Asked Questions — AK Tie Back Women's Swimsuit

Measure your chest, waist, and hip using a soft tape measure directly against your skin. Compare all three measurements 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 on the best fit.

If your measurements fall between two sizes, speak to a member of staff at Allens who will be happy to advise. The adjustable tie back also gives you some flexibility to fine-tune the fit across the shoulders, so a slightly larger size can often be adjusted to fit comfortably.

Carvico Darwin PBT is a premium Italian technical fabric widely used in competitive and training swimwear. PBT (polybutylene terephthalate) fibres are exceptionally resistant to chlorine and retain their shape and elasticity over time, unlike standard polyester or nylon fabrics. The result is a swimsuit that looks and feels as good after hundreds of sessions as it did when new.

The tie back straps can be adjusted by loosening or tightening the ties at the back of the suit before putting it on. Once on, fine-tune the tension so the suit sits flat across the shoulders and back with no pulling, gaping, or pressure. The ties should be secured with a bow that will hold in the water — avoid tying too tightly as this can cause discomfort during longer sessions.

Yes. The AK Tie Back is made from Carvico Darwin PBT fabric which is specifically designed for regular pool use. Its high chlorine resistance means it will retain its shape, colour, and elasticity far longer than standard swimwear, making it an excellent choice for daily training. The fully lined construction also ensures comfort and opacity throughout the session.

The AK Tie Back provides UV protection through the fabric construction, helping to shield your skin during outdoor training, open water swimming, and poolside activities. This makes it a versatile choice for both indoor and outdoor swimming. Always use additional sun protection on exposed areas for extended outdoor sessions.

Rinse the suit in cold fresh water immediately after every use to remove chlorine and salt. Hand wash gently if needed using a mild detergent. Do not machine wash, tumble dry, iron, or bleach. Dry flat away from direct sunlight — UV exposure during drying can degrade the fabric over time. Store in a cool, dry place away from rough surfaces.

The AK Essentials range offers top-quality swimming equipment and swimwear at an affordable, unbranded price. Every product in the range uses high-specification materials and construction — the AK Tie Back, for example, uses the same Carvico Darwin PBT fabric found in much more expensive branded swimwear. AK Essentials is designed for swimmers who want performance and durability without the premium brand price tag.
