Absolutely love the custom packaging it came in!! The binder is the perfect fit, even as my shoulders gain muscle!


I am overwhelmed at how good this binds!!! I have quite a large chest and have always felt dysphoric with it but this does an amazing job at binding them to almost flat. I highly recommend getting this!!!
It is slightly uncomfortable around the arms but it’s not too bad.

Thanks so much for the review! Glad you love this binder :)

Tri Top chest binder size S

Excellent compression! It makes my chest almost flat (35 cm) and I can still breathe well in it! People noticed the difference instantly and it’s still comfortable! I thought I’d never be able to achieve this flat of a chest but SDH made that possible.

Shipping was fast and they were so good with the returns (I ordered a L and it was way too big cause I’m built like a twig) :)

Recommend this binder if you want a super flat chest!

Binds the best of the three underworks options

I bought one each of the tri top, economical, and cotton lined binders.
- the tri top binder binds the best of the three
- I have sensory sensitivities and this one is decently comfortable
-the neckline is the highest of the three so its visible under some clothing
- it's less comfortable than the cotton lined one
- it digs in a little under the arms

There are a few things I wish I could change, but this binder is definitely one of the better ones for balancing flatness with comfort.

good binder

i have a small chest but its binds well and isn’t super uncomfortable.

some people say the arm holes are too small but as a chubby person they were fine for me.

i wear primarily men’s shirts and the neckline usually doesn’t show.

i find that the bottom rolls up sometimes, to try and stop this i’ve sewed the bottom of a tshirt to the bottom of the binder, it helps a little but i don’t think its a preventable issue.

over all works well for me!
