Shoulder pads stop somewhere, and that is exactly where the torso is left open. Rib protection appears nowhere on the list of mandatory equipment: it is a choice, not a box to tick. This guide starts from the IFAF rulebook, then compares the three families of torso protection using only what the manufacturers publish.

The 2-minute summary
- Optional under the rules: IFAF rule 1-4-3 lists nine mandatory items. A rib protector is not one of them.
- Three families: the protector that mounts on the shoulder pads, the padded shirt or vest worn underneath, and the girdle.
- A girdle does not protect the ribs: McDavid states protection at the "hips, thighs and tailbone" for the HEX Thudd Short, not at the torso.
- Compatibility decides everything: the Schutt XV Varsity Rib Protector is built to integrate with the brand's own shoulder pads and ships with its attachment hardware.
- No certification: no NOCSAE, SEI or CE claim on the Schutt, McDavid and Shock Doctor pages consulted. Unlike the helmet, nothing regulates rib protection.
- The back is a separate job: a back plate such as the Xenith Velocity Back Plate covers the lower back, an area a side-mounted rib protector leaves open.

What the rules require, and what they do not
The IFAF Football Rules and Interpretations, 2026 Edition, sets out the mandatory equipment in rule 1-4-3. Nine items, no more: helmet, hip pads, jersey, knee pads, mouthguard, trousers, shoulder pads, socks and thigh pads.
A rib protector is not on that list. No rule consulted forbids one either: it is simply left to the player. Two further points from the same text are worth knowing, because they dictate what you actually have to buy:
- rule 1-4-4-b requires hip pads to include a tailbone pad;
- rule 1-4-4-d requires knee pads to be covered by the trousers, and bans any pad worn on the outside of them.
In other words, the rules oblige you to protect the pelvis and the knees, and leave the torso up to you. If you are after that optional layer, it lives in the rib protectors collection, itself part of football protection. The rest of the mandatory list is spread across football helmets, mouthguards, football apparel for the jersey (such as the Barnett FJ-2) and trousers (such as the Barnett FP-2), and football shoulder pads.
What your shoulder pads already cover
Before adding a piece of kit, look at what your shoulder pads claim. The cut changes how far the coverage reaches down the flank.
Schutt describes the cut of the XV Flux All-Purpose as a full Tactical Full-Arch, intended for players exposed to impact, and sells it as "designed for a wide range of positions" without naming any. The VICIS ARC_V1 Varsity Trench does the opposite: the maker reserves it for line positions, "OL, DL, DE, TE", with CURV thermoplastic composite arches and epaulette and an included back plate.
That is the whole point: a full arch sits lower on the flank than a split-back Skill cut. The gap a rib protector is meant to fill is not the same size depending on the pads you already wear.
The lower back is a case of its own. The Xenith Velocity Back Plate fastens with adjustable coated nylon straps, fits all Xenith shoulder pads and most other brands, and covers that area only. Back plates and rib protectors do not replace one another; our guide to what a football backplate does covers the attachment and sizing.
The three families of torso protection
1. The protector mounted on the shoulder pads
The most direct answer: a padded piece that fixes under the shoulder pad and extends down over the ribs. The Schutt XV Varsity Rib Protector is the catalogue example. Schutt lists seamless integration with shoulder pads, a coated belt connection, multi-height adjustment, hybrid cushioning, raised corrugation, an antimicrobial treatment and attachment hardware included. It comes in two sizes only, S/M and L/XL, and is intended for Schutt XV Varsity shoulder pads. Schutt also sells a youth version, the Flex Youth Rib Protector, built to integrate with youth shoulder pads, with the same coated adjustable belt and an antimicrobial treatment, in S/M and L/XL. The Douglas D2 Rib Protector shows the same dependence on the pad series: removable and wrap-around, it is built for D2 series shoulder pads, with extra grommet holes to raise or lower the rib assembly, and Douglas warn that other series may need adjusting. The VICIS ARC_V1 Rib Protector follows the same logic for ARC_V1 shoulder pads: removable internal thermoplastic composite plates to adjust stiffness, Diamond-Stitch padding and a hook-and-loop closure, with its mounting hardware (T-Nut, Torx 15) sold separately.
Hold on to that last point: compatibility is the first criterion. A protector designed around one attachment system will not necessarily fit another brand.
2. The padded shirt or vest
The second approach is a garment with integrated pads, pulled on under the shoulder pads. The McDavid HEX Sleeveless Shirt / 5-Pad protects "the shoulders, ribs and spine" with 5 pads of 9 mm HEX, in an easy-on, easy-off design; its HEX Sternum Shirt targets the sternum and chest area and comes in youth as well as adult sizes. Shock Doctor states that its Showtime Rib/Back Protector delivers protection for "the lower back, kidneys and ribs", made for youth tackle players. Barnett sell three of their own: the FS-09, a 4-piece compression shirt covering the ribs, shoulders, sternum and lower back; the FS-08, the long-sleeved equivalent, which adds a fifth pad at the elbows and runs from S to 3XL; and the MBP-01, a lighter wrap with its own adjustable back strap.
The McDavid HEX Sleeveless Shirt and the two Barnett models above are in the AFG catalogue today; the HEX Sternum Shirt and the Showtime Rib/Back Protector are here only to describe the family. Its appeal is covering several zones at once without depending on an attachment system; its limit is foam thickness, lower than that of a rigid shell.
3. The girdle, and what it does not do
The third family is the one most often confused with the other two. For the HEX Thudd Short, McDavid states 9 mm HEX protection at the hips, thighs and tailbone, with a cup pocket (cup sold separately). The VICIS Padded Compression Shorts rely on five separate protection zones in auxetic foam with mesh panels.
In both cases, nothing for the ribs. The girdle is the item that satisfies the regulatory requirement for hip pads and a tailbone pad. It does not stand in for a rib protector, and the reverse holds just as firmly. Our guide to choosing a girdle covers sizing and the pad layouts.
Side by side
| Family | Areas claimed by the maker | Attachment | Catalogue example |
|---|---|---|---|
| Protector mounted on shoulder pads | Ribs and flanks | Belt and hardware, multi-height adjustment | Schutt XV Varsity Rib Protector, Schutt Flex Youth Rib Protector, VICIS ARC_V1 Rib Protector |
| Padded shirt or vest | Shoulders, ribs, spine, sternum depending on model | Garment worn under the shoulder pads | McDavid HEX Sleeveless Shirt / 5-Pad, Barnett FS-09, Barnett MBP-01 |
| Girdle | Hips, thighs, tailbone | Garment worn under the trousers | McDavid HEX Thudd Short, VICIS Padded Compression Shorts |
| Back plate | Lower back | Adjustable straps on the shoulder pad | Xenith Velocity Back Plate |
Which positions
No manufacturer consulted names a position for its rib protectors. They all segment their shoulder pads by position, however, and that is where the real need for torso coverage shows up:
- Line positions (OL, DL, DE, TE): VICIS reserves its Trench cut for these roles. Coverage there is already at its maximum.
- Skill positions (QB, WR, DB): Schutt reserves its Skill cut for these roles, and Xenith sells its Velocity 2 for "QB, RB, WR, and DB positions" with All Purpose coverage. Skill cuts, with their split back, favour range of movement.
- All-round players: Schutt sells its All-Purpose cut for a wide range of positions, with a full arch for players exposed to impact.
The practical rule that falls out of this is not about position but geometry: the more your shoulder pad cut favours mobility, the larger the area left open on the flank.
FAQ
Are rib pads compulsory?
No. Rule 1-4-3 of the 2026 IFAF rulebook lists nine mandatory items and a rib protector is not among them. Do check your national federation's rules, which may adapt rule 1 to local requirements.
Is a rib protector certified like a helmet?
No. None of the manufacturer pages consulted (Schutt, McDavid, Shock Doctor) claims a NOCSAE, SEI or CE standard for these products. The helmet is the only item whose certification the rules require.
Can I fit any rib protector to my shoulder pads?
No. The Schutt XV Varsity Rib Protector is advertised for seamless integration with Schutt XV Varsity shoulder pads and ships with its own hardware. Check the compatibility the maker states before you buy.
Does a girdle protect the ribs?
No. McDavid states hip, thigh and tailbone protection for the HEX Thudd Short. The girdle answers the hip pad and tailbone pad requirement, not torso protection.
