Longline gym vests sit in a category of their own — longer than a standard vest, shorter than a crop top, and built to move with you through every rep, stretch and sprint. This edit brings together seamless construction, built-in bra support and breathable fabrics in a cut that works hard whether you're in the weights room or on the mat.
From ribbed textures to ultra-seamless knit, the range covers a handful of carefully designed styles in multiple colourways — so whether you're after a muted grey or something with a bit more edge, there's a longline gym vest here built for it.
Who This Collection Is For
These longline vests are designed for women who want a single layer that does more. If you'd rather skip the separate sports bra and vest combo without sacrificing coverage or comfort, the built-in shelf bra styles in this range sort that out cleanly.
They suit anyone who moves between gym and studio regularly — training sessions where you need a close fit that feels secure, yoga or Pilates where you want fabric that moves without pulling, or low-key days when you want something that feels as good off the mat as on it.
When to Wear Women's Longline Gym Vests
Longline gym vests earn their place across a wide range of training styles. The seamless construction and stretch fabrics make them a natural fit for yoga, Pilates and mobility work — no friction, no distraction, just fabric that follows your movement. They're equally at home during weight training sessions, where the longer cut gives extra coverage when you're loading up or moving through big ranges of motion.
Beyond the gym floor, they work as a solid layering piece under a hoodie or worn solo on rest-day walks and low-key outdoor sessions. The relaxed-but-structured cut means they don't look out of place outside of a gym setting either.
Key Features
Built-In Shelf Bra
Several styles in this range come with an inner shelf bra — no separate sports bra required. It's a practical detail that keeps your kit count down without leaving you short on support during training.
Seamless Construction
The seamless styles are knitted in a way that removes traditional seam lines from high-friction areas. The result is a smooth feel against the skin that holds up through longer sessions without rubbing or chafing.
Stretch Fabric That Moves With You
The fabrics used across this range are chosen for their stretch and recovery — meaning the vest moves with your body rather than fighting it. Whether you're in a deep squat or a full overhead press, the fit stays consistent.
Longline Cut for Extended Coverage
The longer hem length is the defining feature of this category. It sits below the waistband of most leggings and shorts, giving a clean, layered look and added coverage exactly where you want it during training.

Women's Longline Gym Vests FAQs
A longline gym vest is a longer-cut training top that extends further down the torso than a standard vest or crop top. It typically sits at or just below the hip, offering more coverage during movement-heavy workouts. Many styles also feature built-in shelf bras, making them a versatile one-layer option for the gym.
Generally, yes — but the best approach is to check the size guide on the individual product page before ordering. Seamless styles tend to have a close, stretchy fit, so if you're between sizes or prefer a slightly more relaxed feel, it's worth sizing up. The fit notes on each product page will flag anything specific to that style.
Yes. Several styles in this range — including the Ribbed Tank Top With Built-in Bra and the Tempo Ultra Seamless Longline Vest — feature an inner shelf bra. It adds a layer of support so you don't need to wear a separate sports bra underneath, which simplifies your kit for lighter to moderate-intensity sessions.
They're a solid choice for yoga, Pilates, gym training, and studio classes — anywhere you want fabric that moves with you and is designed to feel secure. The longer cut is particularly useful during exercises involving bending, stretching or overhead movement, where a shorter top might ride up. They also work well as a layering piece for walks or casual wear.
Check the care label on your specific vest before washing — instructions can vary between fabric types. As a general rule, seamless and stretch styles last longest when washed on a cool, gentle cycle and left to air dry rather than tumble dried. Avoid fabric softeners, as these can break down stretch fibres over time.
Head to the individual product page for fit notes, model sizing information and the full size guide. These give you the best picture of how a specific style sits and moves before you commit to a size. If you're unsure between two sizes, the size guide is your most reliable reference point.
The vests are designed by Myprotein's in-house design team. Every style is developed with training function in mind — from fabric selection and seam placement through to the details like built-in bras and seamless construction.
Absolutely. The clean lines, minimal detailing and versatile colourways in this range mean these vests sit comfortably outside of a gym context too. Pair with joggers or shorts for casual days, or layer under an open shirt or hoodie for a straightforward off-duty look.
