Similar in design to the Tri-Top, this binder falls to about the belly-button area, and features the same basic shape and feel. It is made with one layer of a sturdy binding nylon/spandex material, and one layer of a poly/cotton blend. Designed to be reversible, this means that the binder can be worn with the cotton against the skin (cozy!) or facing out, imitating the look of an undershirt. Also: no seams! If you’re seeking a more comfy alternative to the Tri-top, this binder is for you!

Powerful medical grade 70% Nylon and 30% spandex knit shell lined with cotton spandex blend.

Comfiest binder I’ve tried!

I love this binder so much! I got two in white and they’re super comfy and blend in really well under t-shirts and button ups. They’re not solid on the front like a lot of other binders, which I like as I have asthma and can’t wear that style for very long. These ones also don’t rub at the seams so are great for all day wear. I have a medium size chest without a binder (38E) and these flatten me to the point of just looking like I have pecs/normal chest fat for my body type.

I will say - if you’re someone who will be wearing these every day, I’d recommend you get two or more and switch them out as they do stretch a bit the more you wear them, but they tighten up again after washing (think jeans).

Love this binder

First binder I have purchased. I love the soft cotton feel, although the fabric does start to pill after plenty of wears. It's a great binder, my only wish is that the straps were a little shorter to fit my frame. Overall, a great purchase!

Great Starter Binder

Tried this on in store and loved the feel of it. This one was recommended to me as a good first-time binder since it is a bit softer and more breathable. My chest measurement is 44'' and I got the XL and it fit comfortable while still compressing my chest. Very excited to wear this and very grateful for the kind customer service :-)

Had this binder for 2 years, works well.

Super comfortable and versatile binder! It's my daily go-to.

This is a great top! My cousin finds it comfortable, which is amazing, after trying several other brands of chest binders which did not work at all. I definitely recommend it!

Very comfortable!

The binder fits snugly. The cotton lining is very soft and comfortable against the skin! If you have sensory issues it could be more comfy than others.
