"I swim laps four mornings a week. Most suits go see through and saggy by month two. This one still looks new after a full season of chlorine."

The fabric
One swim fabric, engineered three ways.
We started with the cloth, not the cut. Tide Flex is knit from regenerated nylon, then bonded so it stretches four ways and snaps back every single time. No bagging at the seat, no sag at the strap.
Four way stretch
Moves with a dive, a paddle and a stretch, then recovers its shape so it never goes slack mid swim.
Chlorine and salt safe
Resists the fade and stiffness that wreck high street swimwear after a few pool sessions.
Soft, second skin feel
Brushed inner face that feels smooth on the skin, dry to the touch in minutes out of the water.

The fit
Designed to stay put, all day.
Tested on real swimmers across a 6 to 18 size run. Wider straps that do not dig, supportive linings that do not show, and leg lines cut to flatter from the first wear to the hundredth wash.
Secure through the surf
Adjustable, no slip straps and a snug back band keep everything in place when the waves do not.
Removable cups
Shaped, removable padding gives clean support and pops out for a faster dry and an easier wash.
Sizes 6 to 18
A full size run with a 60 day fit window, so you can try it on at home and swap with zero fuss.

"Wore it surfing in Cornwall and it did not budge once. Dries on the drive home too. Genuinely the comfiest swimwear I have owned."

"Ordered the set and the size guide was spot on. Straps stay put, no digging, and it actually flatters. Already bought a second colour."

Tide vs the high street
Why a swim set beats a cheap suit.
A high street suit costs less on the tag and far more over a summer. Here is the honest comparison.

Good to know
Questions, answered.
How does the sizing run?
Tide runs true to UK high street sizing with a slightly more supportive cut. Use the size guide above and measure your bust, waist and hip. If you are between sizes, size down for a snug surf fit or up for a relaxed pool day. Returns are free for 60 days, so it is easy to swap.
Is it really chlorine resistant?
Yes. Tide Flex is knit and bonded to resist the fade, stretch and stiffness that chlorine causes in standard swimwear. With normal care it holds its colour and shape across a full season of pool swims. Rinse in cool water after each swim and dry flat in the shade to get the longest life from it.
What does the Surf Season Set include?
The set is the Tide Flex swim top, the matching swim bottoms and a packable quick dry tote. Bought together it is 20 percent off the price of the three pieces separately, with free delivery and 60 day returns included.
How long does delivery take?
Delivery is free on every order. Standard delivery typically arrives within 3 to 5 working days, with tracked and express options at checkout. You will get a tracking link by email the moment your set ships.
What is the return policy?
You have 60 days to return or exchange, even if you have tried it on at home. Items should be unworn in the water with hygiene liners intact. Start a return from your order email and we will send a prepaid label. Refunds land within a few days of us receiving the parcel.
How should I care for my swimwear?
Rinse in cool fresh water after every swim, hand wash with a gentle detergent, and dry flat away from direct heat and sun. Skip the tumble dryer, wringing and fabric softener. Treated this way, Tide keeps its stretch and colour season after season.
