Whether you’re heading to the beach or the pool, this Sleeveless Compression Swim Top by Underworks will arm you with confidence. Although not offering the extreme compression of a traditional chest binder, this is a safer and more comfortable option for chest compression while being active. It is designed to move with your body while offering chest, hip and tummy compression.

Also, if you're looking for a safe binder to work out it outside of swimming, this is a great option. 


  • Inner layers provide compression that helps shape your body, whether it’s flattening the chest or limiting curves in the hip area
  • Seams positioned to eliminate bunching for a smooth appearance
  • UV-resistant microfibre fabric provide SPF 50 protection and give this garment the appearance of a regular zip-down-the-front swim top
  • Designed to move with your skin for more comfortable wear and eliminate bunching, shifting, or ride-up

Colour: Black. Also available in Blue/Black

Material: Shell: 77% Nylon / 23% Spandex Lining: 70% Nylon / 30% Spandex

Customer Reviews

Based on 4 reviews

It's very comfortable and doesn't feel too tight to swim or hike in, but still gives me enough compression to be confident going out. Thank you!!

Excellent fit

I’ve not had the chance to wear it in the water but the colour and fit was amazing, discreet packing. I would highly recommend this company.

Exactly what I ordered

This binder is exactly what I needed for everyday life, swimming, light workouts, etc. I wear this almost everyday all day and the lighter compression really helps me be able to get through a day without the consequences of a normal binder. I'm a broad guy and this makes my chest look really nice! It gives me a fairly masc shape under clothes and the material is extremely sensory friendly too!

I highly recommend this to anyone who needs a lighter compression, something masc to swim in or just to experience a different type of binding in general.

A Must Have

This makes it comfortable for me to use my local pool. So much better than putting a t-shirt over swimmers that floats about and drags on you swimming. This provides a nice flattening profile and is easy to swim laps in. Also stays where it's put.
And a thank you to the lovely people at SDH, beyond great customer service 😀
