Hey everyone,
I learned from this thread
https://www.susans.org/forums/index.php/topic,164452.0.html about the GC2 compression shirts, and I bought one to try out since it's really affordable compared to Underworks. So I thought I would write up a quick review of it here, since I don't make videos or anything about my transition, and I didn't find many reviews of the GC2 done by trans people before I bought it.
Full product name: GC2 Gynecomastia FTM Chest Compression Tank, size XS (mine is in white, it also comes in black and nude)
Cost: $19.99 + ~$6.00 shipping USPS
I just got it today and tried it on a bit, and I have to say that for me, with a small chest, it works just about as well as my Underworks one, but MUCH more comfortable. With a t-shirt over it there is no problem at all, it just looks like I have nice pecs if you were to pull the shirt tight across my chest. It also lays on my shoulders much better and is not stiff at all, unlike my Underworks one, where I have the problem of the shoulder straps sticking out under a t-shirt, which means I haven't been able to wear just a t-shirt without it looking funny. It also has high arm holes, which some will like and some might not. Personally they don't bother me and I think they help with compression a bit and giving a natural look. I think the GC2 will be much cooler and more comfortable, especially for the summer months (Underworks binders can get pretty hot as I'm sure many of you know). The material is very soft and light-weight, but not flimsy and it seems well made. It is made in the U.S. of 70% polyester and 30% spandex. The size I got was XSmall/32-34 which fits well (for reference I'm 5'2", around 102lbs, and I usually wear a size 34S in jackets, blazers, etc.)
Also a note on their customer service, which I had read mixed reviews of in the comments of a review of their shirts: I ordered with a Paypal 'e-check' on June 5, and the check cleared on the 10th. I never got a notification that it shipped so after giving it several days I emailed them and asked about it. They got back to me right away and said it was an oversight while waiting for the e-check to clear, and mailed it out right away the next day. When I got the package today I found that they had sent me an extra shirt, due to the oversight and delay in sending it out. So I would say that despite their mistake they certainly rectified it and I am very satisfied with everything.
Overall, I would highly recommend this shirt if you have a pretty small chest. I can't recommend it for those with larger chests because I just don't know how it would work for them, but I would guess that they might need stronger compression.
Effectiveness (for my and similar chest sizes) - 4/5
Comfort - 5/5
Value - 5/5
Feel free to ask any questions you have. Perhaps later I will do a photo comparison between my Underworks and my GC2 shirts. I hope this was helpful.
