'Ruth Astle // STP Collection' Single Strap one piece swimsuit
Kay Dawson
Top 5 worldwide swimsuit

I am hoping this suit will make me as fast as Ruth! I bought probably a size too small (hoping for that training season weight regulation magic to happen!) but it is stretchy and doesn't make me look all muffin top - credit to the design team all round!

Love my STP swimming cossie

These swimming cossies arw the best I've ever worn. The fabric is so soft, and they feel amazing when you wear them. I'm 5 foot 9 and I wear a medium.

Excellent! Ruth Astle // STP collection one piece swimsuit

I was so excited to receive this swimsuit - I've only taken it for one swim but I'm in love. The sizing instructions were really useful and I bought a small which is on the skimpy side but I feel great in it! ( (I know sizing is so variable across brands, but find it helpful to hear other people's experiences so I'm 164cm and wear size 10/12 clothing) The fabric is of the highest quality that I can tell will last, it also feels lovely to wear. The postcard with a note from Ruth was such a nice touch, as well as the swimsuit looking and feeling great knowing that I'm supporting a small female run business and female pro is really important. Thank you!

'Ruth Astle // STP Collection' Tri Shorts
Rachael Sanderson

I'm not a triathlete, I just run. Wore my shorts on a 10k and they were sooooo comfortable. The design is perfect, everything has been thought of. If I can be super critical about one thing it's that the waistband sat a little too low to what I would normally like but once I was running they settled and I didn't try to pull them up once which is what I normally spend my runs doing. This isn't the first piece of kit I've bought from STP and it certainly won't be the last. The thought and care that goes into each piece is clear. Can't wait to wear these shorts for my first marathon this year.

Ruth Astle STP swimsuit

beautiful colours & pattern, great quality material, but sadly the largest size -3XL -still doesn't fit a UK size 18 :( Italian sizes are very very different to most European sizes...

Just delivered

I can't wait to wear them in spin class tonight !

My favourite design!

I love these shorts. This is probably my favourite design and I love wearing them for cycling and running. Love the waist which is high enough to be forgiving but no high enough to dig in anywhere. My only regret is not getting a trisuit too!

Love my STP singlets!

Spring blossom is probably my favorite design so far. I love the vibrant blues and greens. My favorite training outfit for any run, long or short is my STP singlet and STP tri shorts

Bold and beautiful

Absolutely love these sports bras. This design is bold and beautiful. I highly recommend for those needing an amazing sports bra that keeps you supported when you need it the most. No chaffing just amazing for and feel.

Short sleeved aero suit

Gorgeous colours, lush fit and absolute first class service and a free locked coin which is great for me as I miss place them daily 🤦🏽‍♀️


A beautiful design and gorgeous lightweight fabric. Love it so much!

Such happy shorts!

I debated for ages whether to take the plunge and get my first piece of STP kit and I love them! I went for size medium and would normally wear small (UK 8-10) and definitely couldn’t go any smaller. They’re comfy on the turbo and outside and I love looking down and seeing the happiness!

Wonder Buff!

Gorgeous colours, perfect stretch tension for hair/neck/face options and such a lovely design!!

Brilliant ideas, vibrant colours! Whether you’re a Tri newbie, or you’re experienced, there’s something for everyone. Would definitely recommend.

Swimming cossie

Absolutely love the Forget Me Not design. I've got 4 swimming cossies from stomp the pedal now, the quality is amazing. I'm 5 foot 9 and wear aesium for the extra length.

Women's Sports Bra - Teal
Claire Warburton
STP Sports Bras are the best - FACT!

No chafe, no movement and quality is excellent. I have never found a sports bra that doesn’t cause rubbing after a certain time. This does exactly what it says it does! Worth every penny!


Most comfortable tri shorts I own, design is great with very big pockets for nutrition. Highly recommend - thank you STP!

Love it!

Amazing fit, style and design. Would highly recommend. Just absolutely lush.
