The material is very comfortable and light while still being tight where it needs to be.The mesh back is super breathable and nice for hotter weather. It does a decent good of binding breasts down. It won't completely make you flat if you have bigger breasts but it does help make you feel more comfortable for transitioningMy teen needs a binder to fully express their gender identity in their look, so I bought them this binder as soon as I noticed it in the AmazonVine listings. Our only regret is that it is not quite their size. The construction of this binder is absolutely excellent with a good, stiff material on the outer front to confine the protrusions of femininity, but soft knit material on the front inside for comfort. The back is made of power mesh that both allows for the garment to be pulled on, but also maintains a firm hold. Or at least it would if it were their size. They probably need an extra-small. I am so impressed with the materials and design, however, that I think it would be worth my time to sew the binder in at the sides to make it fit them.They did have another binder before this one, but the front fabric was too stretchy to make the difference that they wanted. This one is great and we will probably buy another one for them if they are happy with it after the alteration.i got this for my older brother who is ftm. he said its super comfortable and really helps him pass as flat chested.I ordered this Binder for my teen in Black, Size 3XL. It is a little short, but it is very comfortable and works well. The mesh back is a nice aesthetic. The material is moisture-wicking which makes it comfortable in warmer weather. The price is great.Fits as expected. Nice comfortable binding. Breathable back. Adorable tag too! Great for gifting!
