Size Guide

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.

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.

Men's pieces — how each one is cut

Oversized Tee

300 GSM cotton, dropped shoulders, relaxed through the chest and body. This is the roomiest thing we make, and it is 100% cotton — there is no stretch in it and it will not give with wear.

If you want the intended oversized look, take your usual size. If you'd rather it sat closer to the body, take the size below.

Essential Tee

130 GSM polyester in a regular athletic fit. Light, close to the body without clinging, no meaningful stretch.

Cut straighter than the Oversized Tee. If you are between sizes, or you carry width through the chest and shoulders, take the larger.

VAULT Performance Training Tee

135 GSM polyester in an athletic slim fit, with panelled construction and curved seams that follow the body.

This is the closest-fitting top in the range. It is designed to sit near the body — if you want room, or you are between sizes, take the larger.

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.

VAULT Performance Training Shorts

180 GSM polyester with 10% spandex, loose through the thigh, cropped above the knee, drawstring waist.

The loose cut and the stretch make these the most forgiving piece we sell. Take your usual size.

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 and thighs rather than your waist. If you are between sizes, take the larger — a heavyweight fleece that is tight through the thigh stays tight.

Women's pieces — how each one is cut

Women's Essential Leggings

220 GSM in 75% nylon, 25% spandex. High-rise waistband, four-way stretch, cut true to size.

Take your usual size. The stretch content is high enough that these accommodate a range rather than sitting on one exact measurement.

Women's Halter Sports Bra

220 GSM in 75% nylon, 25% spandex. Halter neck, open back, cut true to size.

Take your usual size. 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. It is best suited to low and moderate impact training.

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.

How to measure yourself

Use a soft tape, keep it level, and don't pull it tight. Measure over underwear rather than over clothes.

• 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.

For tops, chest is the measurement that decides the size. For joggers and leggings, hips matter more than waist.

Exact garment measurements

We're publishing the full centimetre-by-centimetre measurement tables for every piece shortly, straight from the manufacturer's specification rather than estimated.

If you want a specific measurement before that lands — chest width on a 2XL Oversized Tee, inside leg on a large jogger, anything — email info@prvaultshop.com with the piece and the size and we'll send it back the same working day. We would much rather answer that question than process a return.

If you get it wrong

You have 14 days from delivery to tell us you want to cancel, and a further 14 days to send it back. You don't need to give a reason, and we pay return postage.

Email info@prvaultshop.com with your order number and we'll arrange it. Full detail on the Returns & Refunds page.
