What is Singlet?
Singlet is the skin-tight, one-piece uniform every powerlifter wears on the platform, typically made from a lycra, nylon, or polyester-spandex blend. Unlike the supportive suits used in equipped powerlifting, a competition singlet is designed to give literally no mechanical help with the lift — its only job is to fit closely enough that referees can clearly judge hip crease depth in the squat, chest contact in the bench press, and lockout position in the deadlift, without loose fabric obscuring the view.
How it works
A singlet works simply as a uniform standard, not as performance equipment: because every federation mandates a thin, single-ply, uniformly thick fabric with no compression or elastic rebound, all competitors are judged under the same visual conditions regardless of what they wear underneath. Shoulder straps must stay on the shoulders throughout every lift, and leg length is tightly regulated, roughly 3-25 cm depending on the federation, so it neither covers the knee joint nor rides up in a way that could be mistaken for support. This is the key difference from equipped/single-ply divisions, where lifters additionally wear supportive squat and bench suits designed specifically to store and return elastic energy.
Singlet vs supportive squat/bench suit
| Singlet (Raw/Classic) | Supportive suit (Equipped) | |
|---|---|---|
| Purpose | Uniform only — zero mechanical assistance | Provides genuine elastic support and rebound |
| Material | Thin, single-ply, non-compressible fabric | Multi-ply, engineered for stored energy return |
| Worn in | Raw and Classic Raw divisions (mandatory for all lifters) | Equipped/single-ply divisions only |
| Effect on the lift | None — purely a visibility/judging standard | Can add significant weight to a squat or bench, similar to knee wraps |
A singlet and a supportive suit can look superficially similar, but only one of them is legally allowed to help lift more weight.
By goal
- First-time competitors: Buy a singlet from an approved brand and try it on under real lifting conditions weeks before the meet — a too-tight leg opening can restrict squat depth, and rules staff can reject an unapproved pattern at weigh-in.
- Experienced competitors: Keep a backup singlet in your meet bag; a torn strap or seam on meet day with no spare can turn into a real logistical problem between attempts.
Common misconceptions
- "Any tight one-piece outfit counts as a legal singlet." Federations specify exact material (single-ply, non-compressible, uniform thickness), leg length, and strap width; a singlet that doesn't meet these specs, or isn't from an approved brand/pattern, can be rejected at weigh-in.
- "The singlet provides some support, like a lighter version of a squat suit." A legal raw/classic singlet is specifically required to give zero mechanical assistance — any stored energy or compression support would make it equipment for the equipped division, not a standard singlet.
- "You can wear the straps off your shoulders mid-lift if it's more comfortable." Rules require both shoulder straps to stay on the shoulders throughout every lift; letting a strap slip off during a lift is a real cause for disqualification in most federations.

Singlet FAQ
Why do powerlifters have to wear a singlet?
Singlets are mandatory so referees can clearly see joint positions and lift depth — squat hip crease, bench chest contact, deadlift lockout — without loose clothing obscuring the judging.
What fabric is a powerlifting singlet made of?
Federation rules require a single-ply, non-compressible fabric of uniform thickness, commonly a lycra, nylon, or polyester-spandex blend, specifically so it provides no mechanical support.
Can any singlet be used in competition?
No. The singlet must meet the federation's exact material, leg-length, and strap-width specifications and typically must come from an approved brand or pattern to be legal at weigh-in.
What's the leg length rule for a singlet?
Under IPF rules, the singlet's leg opening must be longer than 3 cm and shorter than 25 cm, keeping the legs visible for judging without covering the knee joint.
Is a singlet different from a squat suit?
Yes. A singlet is a uniform requirement that gives no mechanical assistance, while a supportive squat or bench suit is multi-ply equipment engineered to store and return elastic energy, legal only in equipped divisions.
