Bought for my son - fit is great and nice to buy from UK not USA :)
Have bought a few of these now since my son is transgender and he loves them.
This was a gift and the recipient is well pleased.

This is the first binder I have ever owned and I am well pleased with it!
I am a FTM and considered purchasing this as part of my transition. A lot of places online refer back to Underworks' binders, especially this particular one which I then decided getting. I am about 33,4'' and got the small one which was a real trouble getting on. But once it's on it compresses nicely. Don't give up and think you need a bigger size just because you struggle first; find some helpful videos online and give it a go. You might need to pull it up from stepping into it or, if your hips are too wide like mine, slip it over your head (watch out - you don't want to dislocate your shoulders struggling! Take your time).
It's easy to breathe in and gives some nice looking pecs. For me it ends just above my stomach and doesn't press down on it; it's comfortable sitting, walking and talking in. A great buy!

I am FTM transgender, and this is the second binder type I have tried from Underworks, the first being the tank top/997 style. Of those two, the tri-top is definitely my preference, as the longer 997 would roll up and compress my stomach doubly when I needed no compression there at all.
The quality of all Underworks binders I have tried is really good, and the compression makes my 34C chest almost completely flat. (I bought size small.)
Generally, the fit is very comfortable - it is easy to forget you are wearing one. However, at first the binder material would irritate the skin under my arms a little. As it was not hot, I wore a vest underneath the binder and allowed the vest material to poke out from the binder under the arms, to protect this area from irritation. Once the binder was worn in and washed a few times this problem disappeared.
I experience absolutely no breathing difficulties due to these binders. I exercise hard in them and have never had any problems.
I always handwash my binders, so cannot say how well they hold up in a washing machine. However, I would expect they can handle it on low temperatures as they are very well made. I have been alternating two tri-tops for over a year and they have only just started to show signs of wear, and even now the compression is still very good.
The only complaint I have is that the low part of the neck and the bottom of the binder can sometimes protrude outwards and become visible under t-shirts. I wear fairly loose clothes so don't find this particularly problematic, but for someone who prefers tighter clothing this may be an issue. Leaning backwards or stretching upwards in particular can make the bottom line of the binder very visible.

This binder is not comfortable, but if comfort is what you're looking for you are in the wrong business. It isn't outright painful, but I am usually aware of the compression, and extended wear makes my upper middle back ache. There is some chaffing under the arms but not so much that it becomes unbearable. That being said, you do "get used" to wearing it. It does roll up a little on me, but there's not a lot to be done about that.

The material is a fine mesh that is fairly breathable but it can get very hot.

The tri-top is more comfortable than the double front due to the lack of stomach compression, and certainly outperforms it in terms of binding ability - I have to double over or even "triple over" my double front to get this flat.

I recommend this binder for people with a C cup and above - those with smaller chests may find the double front suits them better, but for my chest (~38DD) I need the extra strength to ah, pull things in.

As with any new binder, the first few days it feels difficult to breathe, until it stretches out a little and you get used to the extra pressure - it should not be dangerously so, however - it should be possible to get in a decent breath, and if not you might need a size up.

The tri-top is suitable for wearing whilst exercising provided that it is of the correct size, but you will find yourself getting out of breath slightly faster.

This binder is much safer than ace bandage alternatives as it does not tighten or constrict as you move or breathe. That being said, binding can still cause/correlates to health problems, and you should avoid wearing it for extended periods - I try not to bind for more than 6-8 hours, and never more than 10. It is also good to take "time off" from binding if you can.

Over the years my breasts have grown to a 30HH and have become more and more uncomfortable for me to have, eating away at my self-esteem. I decided to switch to a binder and this one arrived today, it was incredibly difficult to get on, and using the step in method wasn't an option for me as my hips are far wider than my shoulders.

Once I had got it on it was bunched and rolled up uncomfortably around the top of my back, under my arms and collar bone. At this point in getting it on I recommend you take your time getting it straightened out. Unroll the front as well as you can, then pull up at the back of the neck to unroll at the back, and unroll and pull down under the armpits. Alternate between these movements a little at a time until you can reach the back from the bottom and unfurl it properly.

Once I had got it on it was so comfortable! No straps or underwires to rub or dig in, no cups to migrate out of over the day. :) It hasn't made my chest flat, it never was going to at the size I am, but the shape is now a much more manageable 'front bumper' rather that two 'forward torpedoes with a massive amount of room between'. My clothes now do not strain across the chest and today I feel more confident than I have in a long time!
