The basics deserve the same attention as the rest of your kit. Women's underwear and socks from Myprotein are built with the same performance mindset as everything else in the range — soft-touch fabrics, secure fits, and styles designed to handle whatever your day throws at them.
From multi-pack briefs and bralettes to crew, ankle, and invisible socks, there's a full range of everyday essentials here. Whether you're stocking up or replacing worn-out kit, it's all available in multipacks so you can sort your drawer in one go.
Who This Collection Is For
Anyone who wants underwear and socks that keep up — in the gym, on a run, or just through a long day. The fabrics are chosen for comfort and durability, so these aren't just for training; they work just as well as everyday wear.
If you're already buying your sports bras and leggings from Myprotein, it makes sense to complete the kit here too. The same attention to fit and fabric runs through every piece in this collection, from the briefs to the socks.
When to Wear Women's Underwear & Socks
The bralettes and briefs are built around four-way stretch, so they move with you whether you're lifting, running, or just going about your day. The soft-touch fabric sits comfortably against your skin without riding up or shifting around — exactly what you need when you're focused on something else.
The socks cover everything from low-key training days to longer sessions. Crew styles with ribbed cuffs stay put during workouts, while invisible and trainer socks work under everyday footwear without bunching. Pick the cut that fits the occasion and stock up.
Key Features
Four-Way Stretch Fabric
The briefs and bralettes use a four-way stretch construction that moves with you in every direction. There's no pulling, pinching, or bunching — just a clean fit that stays in place.
Soft-Touch Finish
Fabric that sits directly against your skin needs to feel right all day. The soft-touch finish on the underwear reduces irritation, so you can stay comfortable from your first set to your last meeting.
Secure Sock Cuffs
Crew and ankle socks feature ribbed cuffs that grip without digging in. They stay up during training and keep their shape after repeated washes.
Multipack Options
Socks come in packs of three and five, briefs in three-packs, and bralettes as individual pieces. You can mix styles and colours, or keep it simple and stock up on one go-to option.

FAQs
What sizes are available for the women's underwear?
The briefs and bralettes are available across a range of sizes to suit different body shapes. Check the individual product pages for size guides — each listing includes specific measurements to help you find the right fit.
What materials are the briefs and bralettes made from?
The women's underwear is made from a soft-touch, four-way stretch fabric that's designed to feel comfortable against your skin all day. Check the individual product pages for the full fabric breakdown and composition details.
How should I care for the underwear and socks?
Machine wash on a gentle cycle at low temperature and avoid tumble drying where possible — this keeps the fabrics in shape and helps them last longer. Always check the care label on each individual item before washing.
Which sock style should I choose for the gym?
It depends on your footwear. Crew socks with ribbed cuffs are a solid all-rounder for training — the MP Unisex Crew Socks stay put during sessions and cover your ankle and lower calf. If you're wearing low-profile trainers, invisible or trainer socks are a cleaner option.
Are the briefs suitable for wearing during workouts?
Yes — the four-way stretch fabric and soft-touch finish make the briefs a practical choice for training as well as everyday wear. The MP Women's Mid Rise Bikini Brief is built to move with you, so there's no uncomfortable shifting during exercise.
Can I mix and match styles and colours in the multipacks?
The multipacks come in pre-selected colour combinations rather than fully customisable sets. There are plenty of options across the range though — from neutral tones to bolder colourways — so it's worth browsing to find the pack that suits you.
Who designed the women's underwear and socks?
Everything in this collection is designed by Myprotein's in-house design team. They develop each piece with the same performance and comfort focus applied across the rest of the Myprotein clothing range.
How do the socks hold up after repeated washing?
The ribbed cuffs and structured knit on the crew and ankle styles are built to maintain their shape over time. Washing on a gentle, low-temperature cycle will keep them performing for longer.
