Chest Binder Brands Compared — gc2b, Underworks & More
gc2b, Underworks, and TGS Walk Into a Binder Shop — Here's What Actually Happened
If you've been binding for more than five minutes, you've heard the names: gc2b, Underworks, and whoever your trans friend swore by when you were first figuring this out. The binder landscape has shifted a lot recently — quality complaints, ownership changes, community trust moving around — and if you're trying to decide where to spend your money, you deserve an honest answer, not a sales pitch.
We carry binders from multiple brands here at TGS. We're also trans-owned and trans-run, which means we have opinions. This post is our attempt to give you a genuinely useful comparison so you can make the call that's right for your body and your situation.
The Short Version: What's Changed
A few years ago, the standard advice was: start with gc2b or Underworks, upgrade later. That advice needs updating.
gc2b has seen a documented quality decline. Community reviews and customer feedback consistently note that binders purchased in 2023–2025 perform significantly worse than older ones — less compression, faster wear, and customer service issues that weren't problems before. gc2b is still trans-owned and trans-operated, and older gc2b binders are genuinely beloved. But the current product isn't what built that reputation.
Underworks remains consistent — which is both its strength and its limitation. Underworks was built for cis men with gynecomastia, not for trans bodies. It works well for average proportions, but the sizing doesn't go small enough for many people, cuts into larger bodies, and there's no free size exchange if you get it wrong.
TGS binders — including NYTC cotton binders, racerback styles, and the Sports Bro — are designed for trans and gender expansive bodies. Full stop. They're the reason we built TGS in the first place.
Brand by Brand: The Honest Breakdown
gc2b
What it is: Trans-owned and operated. The brand that introduced a lot of people to safe binding. Known for its half binder and full-length tank in a wide range of nude shades for darker skin tones — something the industry was badly missing when gc2b launched.
What's changed: Recent customers report that new binders provide significantly less compression than older ones, some losing structure within weeks of purchase. The 2.0 update to their core product has been widely criticized. Customer service response times have increased. Their return policy is strict — no refunds, limited exchanges — which means you're taking a risk if the sizing is off.
Best for: Someone who specifically needs gc2b's extended nude shade range, or who is buying a well-reviewed older-style half binder while they're still available. Not our first recommendation for new binders right now.
Underworks
What it is: A cis-owned American compression garment company that makes products for gynecomastia, hernia support, and shapewear. Their tri-top binder (983) and full tank (997) became popular in trans communities because they were cheap, easy to find, and genuinely effective for a lot of people.
What's good: Consistent quality over time. The 997 full tank is durable, holds up well with frequent wear, and offers strong compression for larger chests. Made in the USA. Price point is accessible.
What's not: Underworks was not designed for trans bodies. Sizing doesn't go small enough for many trans masc and non-binary people — a common complaint for years. The tri-top (983) can cut into bellies on larger bodies and pinch armpit fat due to the cut. No size exchange. No trans-owned purchase. The language on their website still centers gynecomastia and cisgender men.
Best for: People with average-to-larger proportions who need maximum compression and aren't concerned about supporting a trans-owned company. The 997 specifically is a solid choice for larger chests. Not ideal for small or petite frames.
Available at TGS:Yes — we carry Underworks because community members ask for it, and we'd rather you buy from a trans-owned retailer than Amazon. But we'll always tell you when one of our own binders is a better fit for your body.
TGS Binders (NYTC, Sports Bro & More)
What it is: The binders we've specifically sourced, tested, and stand behind — chosen because they work for trans and gender expansive bodies across a full size range.
NYTC Cotton Binders — Full and medium compression options in cotton. Better for sensitive skin, warmer climates, and daily wear. Softer feel than nylon/spandex binders. Great for people who find max-compression binders uncomfortable for all-day use. Available in tank and racerback cuts.
Sports Bro — Quick-dry, moisture-wicking, three colorways. Built for movement, workouts, and summer. Works as a swim top. Medium compression — not a max binder, but stays in place during activity in a way that cotton binders don't.
What's different: Free 30-day size exchange on all binders — including sale binders. Discreet shipping from "Shipping Dept." No brand name or product description on the outside. Trans-owned retailer. A 2-minute binder sizing guide to help you get it right the first time.
Best for: Most people. Seriously. If you're not sure where to start, start here — because if the size is wrong, we'll swap it for free.

Which Brand Is Right for You?
If you want max compression on a larger chest: Underworks 997 full tank is a solid, proven option. It's not trans-made but it does the job, and you can buy it here from a trans-owned shop.
If you want a trans-owned binder with a free size exchange: TGS binders are the answer. Cotton for sensitive skin or daily wear, Sports Bro for activity and summer. If the size is wrong, we'll swap it.
If you specifically need gc2b's shade range or had a good experience with an older gc2b half binder and want to try again: we still carry select styles. Just be aware the current product is drawing more mixed reviews than it used to.
If you're binding for the first time: Start with our binder size chart. Get the size right before you order anything. Then take advantage of the free size exchange just in case.
Frequently Asked Questions
Is gc2b still good in 2025?
gc2b is still trans-owned and carries a strong reputation built over many years. However, recent customer reviews note a decline in compression and durability in newer binders. If you're buying new, we'd encourage you to compare options carefully.
Does Underworks make binders for trans people?
Underworks was originally designed for cis men with gynecomastia. Their binders work for many trans and non-binary people — particularly the 997 full tank for larger chests — but the sizing skews larger and the fit isn't designed with trans bodies in mind.
What makes TGS binders different?
TGS binders are sourced specifically for trans, trans masc, non-binary, and gender expansive bodies. Every binder comes with a free 30-day size exchange, discreet plain packaging, and is sold through a trans-owned shop. If the size is wrong, we'll fix it.
