Size Guide
Recorded. Stored. Earned.
Every PR Vault piece is made to order, so it's worth two minutes now rather than a return later. If it still isn't right, you have 14 days and we pay the postage — wrong size counts.
Start here — we use three different sizing systems
Not every piece is sized the same way, and that catches people out. Check which system the piece you're buying uses before you pick.
| Piece | Sizes offered | Sizing system |
|---|---|---|
| Colour Block Oversized Tee | S – XL | Unisex |
| Essential Tee | S – 4XL | Men's |
| VAULT Performance Training Tee | M – 3XL | Men's |
| VAULT Performance Training Vest | S/M, L, XL, 2XL | Men's — S and M are one combined size |
| VAULT Performance Training Shorts | S – 2XL | Men's |
| Cuffed Joggers | S – 2XL | Men's |
| Women's Essential Leggings | S – XL | Women's |
| Women's Halter Sports Bra | S – 2XL | Women's |
| High Rise Flared Leggings | 4 – 12 | UK dress size — not S/M/L |
The two leggings are the ones to watch. The Essential Leggings are lettered S to XL; the Flared Leggings are numbered UK 4 to 12. They are not the same scale, so don't carry a size across from one to the other.
How to read these tables
Every number below is the garment measured flat, in centimetres, edge to edge — not your body, and not the way round the garment. That is why a size S legging shows a 24cm waist.
To compare a chest, waist, hip, bust or underbust figure against yourself, double it. A 53cm flat chest is a 106cm garment all the way round. Length, shoulder and sleeve are already the real distance and need no doubling.
On the leggings, shorts and sports bra the fabric is a nylon or polyester spandex blend measured unstretched, so the garment is built to open up well beyond the figure shown. On the cotton-blend pieces — the Colour Block Oversized Tee and the Cuffed Joggers — what you see is what you get.
These come from our manufacturer's specification. Allow 1–3cm of variation between individual garments; that is normal for cut-and-sew clothing and is the tolerance they work to.
Men's pieces
Colour Block Oversized Tee
240 GSM, 60% cotton and 40% polyester. Boxy, dropped-shoulder cut with contrast raglan sleeves and a ribbed crew neck. Cut oversized and unisex.
Take your usual size for the intended relaxed look, or size down for a closer fit. Because the sleeve is a raglan, the sleeve figure is not comparable with the set-in sleeves on our other tees.
| Size | S | M | L | XL |
|---|---|---|---|---|
| Length | 65 | 67 | 69 | 71 |
| Chest | 61 | 63 | 65 | 67 |
| Sleeve length | 40.5 | 42 | 43.5 | 45 |
Essential Tee
130 GSM polyester in a regular athletic fit. Light, close to the body without clinging, no meaningful stretch.
Cut straighter and narrower than the Oversized Tee — compare the shoulder figures. If you are between sizes, or you carry width through the chest and shoulders, take the larger.
| Size | S | M | L | XL | 2XL | 3XL | 4XL |
|---|---|---|---|---|---|---|---|
| Length | 66 | 68 | 70 | 72 | 74 | 76 | 78 |
| Shoulder | 41.5 | 43 | 44.5 | 46 | 47.5 | 49 | 50.5 |
| Chest | 49.5 | 51.5 | 53.5 | 55.5 | 57.5 | 59.5 | 61.5 |
| Sleeve length | 19.5 | 20.5 | 21.5 | 22.5 | 23.5 | 24.5 | 25.5 |
VAULT Performance Training Vest
185 GSM polyester with 13% spandex, cut in a regular relaxed fit. The spandex means it moves and gives, so it is more forgiving than the tees.
Note the sizing: this piece starts at a combined S/M, so there is no separate small. If you are usually a small, S/M is your size and it will sit a little looser than a true small. The shoulder figure is narrow because it is the strap width on a sleeveless cut, not a shoulder seam.
| Size | S/M | L | XL | 2XL |
|---|---|---|---|---|
| Length | 67 | 69 | 71 | 73 |
| Shoulder | 28.5 | 28.9 | 29.3 | 29.7 |
| Chest | 50 | 52 | 54 | 56 |
VAULT Performance Training Shorts
180 GSM polyester with 10% spandex, loose through the thigh, cropped above the knee, drawstring waist.
The loose cut, the stretch and the drawcord make these the most forgiving piece we sell. Take your usual size. Length here is the full short from waistband to hem.
| Size | S | M | L | XL | 2XL |
|---|---|---|---|---|---|
| Length | 41 | 42 | 43 | 44 | 45 |
| Waist | 35.5 | 37.5 | 39.5 | 42.5 | 45.5 |
| Hip | 54 | 57 | 60 | 64 | 68 |
Cuffed Joggers
340 GSM cotton-rich fleece, tapered leg, cuffed ankle, elasticated waist with a drawcord.
This is heavy fabric with very little stretch. The drawcord handles the waist, so choose on your hips rather than your waist. If you are between sizes, take the larger — a heavyweight fleece that is tight through the thigh stays tight.
| Size | S | M | L | XL | 2XL |
|---|---|---|---|---|---|
| Length | 101.5 | 103 | 104.5 | 106 | 107.5 |
| Waist | 35.5 | 37 | 38.5 | 40 | 41.5 |
| Hip | 51.5 | 53.5 | 56 | 58.5 | 61 |
Women's pieces
Women's Essential Leggings
220 GSM in 75% nylon, 25% spandex. High-rise waistband, four-way stretch, cut true to size.
These are measured unstretched, which is why the figures look small — the fabric is built to stretch a long way and pull back. Take your usual size.
| Size | S | M | L | XL |
|---|---|---|---|---|
| Length | 82 | 84 | 86 | 88 |
| Waist | 24 | 26 | 28 | 30 |
| Hip | 33 | 35 | 37 | 39 |
High Rise Flared Leggings
220 GSM in 80% nylon, 20% spandex — slightly firmer and more supportive than the Essential Leggings. High-rise waistband, flared from the knee.
These run on UK dress sizes 4 to 12. Take the UK size you would buy in jeans. Do not translate from a letter size — an S in our Essential Leggings is not the same scale. Like the Essential Leggings, these are measured unstretched.
| Size | 4 | 6 | 8 | 10 | 12 |
|---|---|---|---|---|---|
| Length | 101.5 | 103 | 104.5 | 106 | 107.5 |
| Waist | 25.5 | 28 | 30.5 | 33 | 35.5 |
| Hip | 36 | 38.5 | 41 | 43.5 | 46 |
Women's Halter Sports Bra
220 GSM in 75% nylon, 25% spandex. Halter neck, open back, cut true to size.
Measured unstretched and flat. This is a compression-style bra with no adjustable strap or clasp, so it is designed to be snug when you put it on — that is the fit working, not the size being wrong. Best suited to low and moderate impact training.
| Size | S | M | L | XL | 2XL |
|---|---|---|---|---|---|
| Bust | 29 | 31 | 33 | 35 | 37 |
| Underbust | 25 | 27 | 29 | 31 | 33 |
What each measurement means
- Chest / Bust — straight across from the stitches below one armpit to the other.
- Shoulder — from where the shoulder seam meets the sleeve on one side to the other.
- Sleeve length — from where the shoulder seam meets the armhole to the cuff.
- Length — on tops, from where the shoulder seam meets the collar down to the hem. On joggers, shorts and leggings, from the waistband to the leg opening.
- Waist — straight across the waistband, edge to edge.
- Hip — straight across the widest point, edge to edge.
- Underbust — straight across the band below the bust, edge to edge.
How to measure yourself
Use a soft tape, keep it level, and don't pull it tight. Measure over underwear rather than over clothes, then halve the number to compare it against the flat measurements above.
- Chest — around the fullest part, under the arms, with your arms down.
- Waist — around the narrowest part of your torso, usually just above the navel.
- Hips — around the fullest part, roughly 20cm below the waist.
- Inside leg — from the top of your inner thigh to the ankle bone.
The simplest check: measure yourself around, halve it, and find the size whose flat figure is a little larger. For tops, chest decides the size. For joggers and leggings, hips matter more than waist.
