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 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.
Features:
- 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/Blue. Also available in Black
Material: Shell: 77% Nylon / 23% Spandex Lining: 70% Nylon / 30% Spandex

Size Guide

How to measure: With arms down by your sides, take a snug measurement around the fullest part of your chest, usually across the nipples without clothing.
Care
- Hand wash regularly in warm or cold water, or wash on a gentle cycle in a delicates bag.
- Dry flat or hang to dry. We don't recommend ironing your binder.
- Do not tumble dry.

Admittedly haven't tried swimming in it yet- But surprisingly, when dry, this is the most comfortable binder I've ever worn! I dunno about everyone else, maybe just me?
I went through multiple spinal surgeries as a squishy kid, so, binding is more risky, and finding a comfortable binder is always tough. BUT The moment I put this on I was super shocked with how comfy it is(?!)- It's not as uncomfortably tight as other binders, but still feels shapely masculine! Made for moving and activity, which is good for my hobbies. Even being short and stocky, I still definitely look and feel flatter in this. The material is admittedly thicker and the scratchiness will get a bit annoying:: but that's because the fabric choice is built for swimming!
But, I'm so pleased with the moveability, evenness of compression with a lack of suuuper tightness, and shape, that I'll probably buy a second one, mostly just for non-swim/daily active use!
Overall, can recommend this even just as a daily binder, especially for those who are just like me with physical disabilities who have trouble binding. Not sure about others who bought this, but for me this has been a great way to bind in a less-tight way compared to standard binders whilst still promoting moveability and looking /realistically/ flat (ie not super tight flat, still a bit of curve, but in line with my middle, so it distributes naturally!). Not so much for those with sensory issues, because that's because the material is made for swimmin! But that doesnt bother me personally so much :) I love it!
Great binder
Best binder for swimming I've bought. I'm a swimming teacher so am in the water 3+ times a week and this binder holds up well. I was a little nervous that this job would make me dysphoric for how visible it would make my body, but this binder gives me so much confidence that I even pass as male in the water most of the time (pre-T, pre-op), which I love. I am now buying my second one of these to replace the one I've been wearing for the last 2 years.
prompt delivery abd the binder is comfterable
This binder is the best one i had bought in 4 years of binding. It’s comfortable and moves with your body while still supporting your chest in the right way. I bought it with the intention of wearing it only for swimming but will be buying a second one for daily use!
