The right underwear and socks aren't an afterthought — they're the foundation of a comfortable training session. MP's underwear and socks range is built for people who move, with soft-touch fabrics, 4-way stretch construction, and designs that stay put through every rep, stride, and stretch.
From bralettes and bikini briefs to crew socks and no-slip pilates styles, the range covers everything you need from the gym floor to everyday wear. Multiple colourways, pack formats, and silhouettes mean you can mix, match, and stock up on the basics without compromise.
Who Underwear & Socks Are For
Anyone who trains regularly knows that friction, bunching, and poor fit are three of the fastest ways to ruin a workout. This range is designed for people who want activewear underwear and socks that keep up with them — whether that's a HIIT class, a long run, a Pilates session, or a full day on your feet.
It's not just for dedicated gym-goers either. The everyday-friendly cuts and neutral colourways make these pieces just as at home under jeans as they are under leggings. If you want basics that genuinely work harder, this is the range for you.
When to Use Underwear & Socks
Training underwear and socks earn their keep in high-movement environments — think strength sessions, cardio, yoga, and Pilates where standard basics tend to shift or irritate. The 4-way stretch construction and soft-touch fabrics mean you're not distracted by what you're wearing when you should be focused on what you're doing.
Outside of training, the same qualities that make these pieces gym-ready translate directly to all-day comfort. Breathable crew socks work just as well in trainers on a commute, and seamless brief cuts sit invisibly under everyday clothes. Grab a multi-pack and have the right pair ready for whatever the day holds.
Underwear & Socks Benefits
Moves With You
4-way stretch fabric is the defining feature across the underwear range. It flexes in every direction without restricting movement, so whether you're lunging, bending, or sprinting, the fit stays exactly where it should.
Stays Comfortable Under Pressure
Soft-touch fabric construction reduces irritation during prolonged wear — particularly relevant during training when chafing can quickly become a real distraction. The materials are chosen specifically for people who need comfort over long sessions.
Socks That Actually Stay Put
Ribbed cuffs on the crew sock styles are designed to keep the sock in place throughout your session. No more stopping mid-workout to pull up a slouching sock — a small detail that makes a noticeable difference.
Range Built for Real Variety
From no-VPL thongs and mid-rise bikini briefs to ballet no-slip socks and ankle styles, the range covers different activities, preferences, and aesthetics. Pack formats — from 2-packs to 5-packs — mean stocking up is straightforward and cost-effective.

FAQs
What gym underwear and socks does Myprotein offer?
Myprotein's MP range includes women's bralettes, mid-rise bikini briefs, thongs, and no-VPL styles alongside a full socks selection covering crew, ankle, pilates, and ballet no-slip formats. Most styles are available in multi-packs — 2, 3, or 5 pieces — across a variety of colourways including neutrals, bold shades, and multipacks mixing several tones in one. Men's cotton boxers are also part of the range.
What makes MP activewear underwear different from regular underwear?
MP activewear underwear is built around two key features: a soft-touch fabric that reduces irritation during movement, and 4-way stretch construction that flexes in every direction without bunching or shifting. These aren't just cosmetic differences — they're the features that make the difference between underwear you forget you're wearing and underwear that distracts you mid-session.
Which underwear would you recommend for the gym?
The MP Women's V-neck Bralette in Fudge is a strong choice for training — its soft-touch fabric reduces irritation during movement and the 4-way stretch means it adapts to every exercise without riding up or restricting. For briefs, the MP Women's Mid Rise Bikini Brief 3-Pack brings the same stretch and comfort benefits in a practical multi-pack format, making it easy to stay stocked up.
Are the socks suitable for the gym as well as everyday wear?
Yes — the crew sock styles are built with ribbed cuffs that keep the sock in place during activity, which makes them practical for training, but the same quality translates directly to everyday wear in trainers or casual shoes. The range includes crew, ankle, pilates, and no-slip ballet styles, so there's a silhouette suited to different activities and footwear types.
What sock styles are available in the MP range?
The range covers several distinct styles: unisex crew socks, unisex ankle socks, frilly pilates socks, and ballet no-slip socks. Crew socks are available in both 3-packs and 5-packs, across colourways including white, black, earth tones, neutrals, and black/white. The no-slip sole on pilates and ballet styles makes them particularly useful for studio-based training where grip matters.
Do the socks come in multi-packs?
Multi-packs are the standard format across the sock range. Crew socks come in 3-packs and 5-packs, pilates socks come in 2-packs, and ballet no-slip socks come in 2-packs. This makes it straightforward to keep a rotation going without constantly reordering — particularly useful if you're training multiple times a week.
Who designs the MP underwear and socks range?
The MP underwear and socks range is developed by Myprotein's in-house design team, who focus on activewear built for real training demands. The fabric choices, construction details, and silhouette options are shaped around the practical needs of people who move daily — not just aesthetics.
What colourways are available in the underwear range?
The underwear range spans neutral tones — including fudge, warm cream, deep chocolate, and brown — alongside bolder options like blush, rose red, deep berry, and black. Multi-packs often combine complementary shades in a single purchase, making it easy to build a varied rotation without buying individual pieces separately.
Is the MP underwear range suitable for low-impact as well as high-intensity training?
The 4-way stretch and soft-touch fabric construction make MP underwear a practical choice across intensity levels — from Pilates and yoga to running and strength training. The no-slip sock styles are particularly well-suited to studio and mat-based activities where grip is important, while the crew and ankle socks work across gym and cardio sessions.
How do I choose between thong and bikini brief styles?
The choice typically comes down to personal preference and the type of clothing worn over the top. The no-VPL thong styles are designed to sit invisibly under fitted activewear and everyday clothes, while the mid-rise bikini brief offers more coverage with the same 4-way stretch and soft-touch fabric. Both are available in multi-packs, so trying both styles is a practical option.
