Shop Base Layer Clothing at Myprotein

When the temperature drops or the intensity rises, proper base layer clothing makes all the difference. Designed to sit close to your skin, base layers create a foundation that works with your body through every rep, run, and recovery session. Whether you're layering up for outdoor training or looking for that secure, locked-in feel during indoor workouts, the right baselayer keeps you moving without distraction.

From high-neck long sleeves to compression shorts, each piece in this collection brings moisture-wicking fabrics and stretchy construction that moves as you do. These aren't just underlayers – they're performance essentials that handle sweat, support your movement, and feel good against your skin from warm-up to cool-down.

Who This Collection Is For

Base layers suit anyone who trains hard and wants clothing that works as hard as they do. If you're hitting the weights room, pounding the pavement, or tackling HIIT sessions, these pieces give you that locked-in feeling that helps you focus on the workout, not what you're wearing. They're equally at home under your favourite gym gear or worn solo when you want that sleek, streamlined look.

From serious athletes who need compression support during intense sessions to weekend warriors layering up for outdoor runs, this collection covers all training styles. The versatile fits work across body types, whilst the moisture-wicking fabrics handle everything from steady-state cardio to explosive power movements.

When to Wear Base Layers

Pull on a compression base layer when you need that secure, supported feel during heavy lifting sessions or high-impact training. The close fit stays put through burpees, box jumps, and everything in between, whilst the stretchy fabric moves with you rather than against you. Perfect for early morning outdoor runs when you need an extra layer that won't bulk up under your jacket.

These pieces transition seamlessly from gym to recovery. Wear them solo during indoor training sessions, layer them under hoodies for outdoor workouts, or keep them on post-session whilst you refuel. The quick-drying fabrics mean you're not stuck in damp clothing, and the versatile designs work whether you're warming up, working out, or winding down.

Key Features

Moisture-Wicking Fabrics

Advanced fabric technology pulls sweat away from your skin, keeping you dry and comfortable through intense sessions. The quick-drying construction means you spend less time feeling damp and more time focused on your performance.

Four-Way Stretch Construction

Stretchy materials move in every direction, giving you full range of motion whether you're squatting deep, reaching overhead, or sprinting hard. The fabric bounces back after every movement, maintaining its shape session after session.

Compression Fit

Close-to-skin design creates that locked-in feeling without restriction. The snug fit stays in place during dynamic movements, eliminating the need to adjust mid-workout whilst providing coverage that feels secure.

Flatlock Seaming

Smooth, flat seams sit comfortably against your skin, reducing friction during repetitive movements. The construction eliminates irritation points, so you can focus on your training rather than adjusting your kit.

FAQs

How should base layers fit?

Base layers should feel snug without being restrictive. You want a close fit that sits comfortably against your skin and moves with you, not loose fabric that bunches up or rides during exercise. The compression design means they'll feel tighter than regular clothing, but shouldn't restrict your breathing or movement. If you're between sizes, consider how you'll wear them – size down for maximum compression or stick with your usual size for a slightly more relaxed feel.

Can I wear compression base layers on their own?

Absolutely. Whilst they're designed as foundation pieces for layering, compression base layers work brilliantly worn solo during training. The moisture-wicking fabrics and secure fit make them ideal for indoor workouts, and the sleek designs look the part whether you're in the weights room or at a circuit class. Just choose the coverage level you're comfortable with – full-length leggings and short-sleeve tops are popular standalone choices.

How do I care for my base layer clothing?

Wash your base layers in cold water on a gentle cycle to maintain the fabric's technical properties. Avoid fabric softener, as it can reduce the moisture-wicking effectiveness. Air drying works best to preserve the stretch and compression qualities, though tumble drying on low heat is fine if you're short on time. Turn compression pieces inside out before washing to protect the outer surface and extend their lifespan.

What's the difference between compression and regular base layers?

Compression base layers offer a tighter, more supportive fit that stays locked in place during dynamic movements. They're constructed from fabrics with higher elastane content, creating that secure, second-skin feel. Regular base layers focus more on moisture management and layering, with a closer fit than normal clothing but without the same level of compression. If you want that supported feeling during intense sessions, go for compression. For everyday training and layering versatility, regular baselayers do the job.

Who designs Myprotein's base layer collection?

Every piece is created by Myprotein's in-house design team, who understand exactly what active people need from their training kit. They combine technical fabric knowledge with real-world training experience to develop base layers that actually perform. The focus stays on practical features that make a difference – moisture control, stretch, durability – rather than unnecessary details that add cost without adding value.

Will compression base layers lose their shape over time?

Quality compression base layers, when cared for properly, maintain their shape and elasticity through regular use. The key is following the care instructions – cold washes, avoiding fabric softener, and air drying when possible. The four-way stretch construction in these pieces is designed to bounce back after every wear, so they'll keep that supportive feel session after session. If you notice any loosening, it's usually down to tumble drying on high heat or washing with harsh detergents rather than the fabric itself wearing out.

What activities are these base layers best for?

These pieces handle any training style you throw at them. The compression options excel during high-intensity sessions like CrossFit, HIIT, or heavy lifting where you want that locked-in, supported feel. The moisture-wicking properties make them brilliant for cardio work – running, cycling, rowing – where sweat management matters. They're equally effective for yoga, Pilates, or stretching sessions where freedom of movement is essential. Outdoor athletes appreciate them as layering pieces that regulate temperature without adding bulk. Basically, if you're moving, these base layers work.

Can women wear the men's base layer collection?

Yes, though sizing might need adjustment since men's cuts tend to be wider through the shoulders and chest with a straighter waist. Many women size down in men's base layers for a proper compression fit, particularly in tops. The compression leggings can work well if you prefer a lower rise and don't mind a straighter leg cut. Check the size guide and consider ordering a couple of sizes to find what works best for your body shape – the stretchy fabrics are forgiving, but the right fit makes all the difference in comfort and performance.
