Men's 2-in-1 Shorts

Shop Men's 2-in-1 Shorts at Myprotein

Men's 2-in-1 shorts are built for the way you actually train — giving you the coverage of a longer outer short and the secure fit of an inner liner, all in one piece. Whether you're lifting, running, or keeping it general in the gym, this range covers the range of lengths, fabrics, and fits you need to move without thinking about your kit.

From 5" training styles to 7" cuts, and from standard woven fabrics to ultra-lightweight mesh constructions, there's a 2-in-1 short here for every training style and preference.

Who This Collection Is For

These shorts are designed for men who want their kit to work as hard as they do — whether that's sessions in the weights room, runs around the block, or back-to-back classes at the gym. The dual-layer construction means you get an outer short that looks the part alongside an inner liner that feels secure, no matter the movement.

If you've ever had to adjust your shorts mid-set or deal with inner shorts that bunch and ride up, you'll understand exactly why the 2-in-1 design makes sense. This range suits everyone from weekend gym-goers to serious athletes training multiple times a week.

When to Wear Men's 2-in-1 Shorts

The 2-in-1 format is genuinely versatile. Wear them for weightlifting and strength sessions where you need freedom of movement through squats, deadlifts, and lunges. Take them out on your runs — shorter 5" inseam options keep things lightweight, while reflective details on certain styles make early morning or evening runs safer.

They're equally at home in HIIT classes, functional training sessions, and general gym work. The inner liner eliminates the need for separate base-layer shorts underneath, streamlining your kit bag and your routine at the same time.

Key Features

Dual-Layer Construction

Every pair in this range combines an outer shell with an integrated inner liner. The liner sits close to the body for a secure, settled feel, while the outer short gives you a clean, gym-ready look without needing to layer separate pieces.

Range of Inseam Lengths

Choose from 5" and 7" inseam options depending on how much coverage you prefer. The 5" cut keeps things lighter and more minimal for running and high-intensity work, while the 7" length suits those who prefer a more relaxed feel through the thigh during lower-body training.

4-Way Stretch Fabrics

Select styles are cut from 4-way stretch woven fabric, meaning the material moves with you in every direction — forwards, back, and side to side. There's no pulling, pinching, or restriction through the hips, regardless of the exercise.

Flatlock Seams and Considered Details

Flatlock seaming on key styles reduces friction against the skin during longer sessions or runs. Additional details like reflective logos on select shorts add low-light visibility for outdoor training.

FAQs

What are 2-in-1 shorts?

Men's 2-in-1 shorts combine an outer short with a built-in inner liner in a single garment. The outer layer looks and functions like a standard training short, while the inner liner sits closer to the body for a secure, comfortable feel. It removes the need to wear a separate base layer underneath and helps the fit feel secure during movement.

What length options are available in the men's 2-in-1 shorts range?

The range includes both 5" and 7" inseam lengths. The 5" cut is a shorter, lighter option popular for running and high-intensity training, while the 7" length offers more thigh coverage — a solid choice for strength sessions or if you simply prefer a slightly longer fit.

Are men's 2-in-1 shorts good for running?

Yes — several styles in this range are well-suited to running. The MP Men's 5" 2-in-1 Training Shorts feature flatlock seams to reduce chafing over longer distances, and a reflective logo for added visibility in low-light conditions. The shorter 5" inseam also keeps the fit lightweight and unrestrictive for continuous movement.

How do men's 2-in-1 gym shorts fit?

Fit varies slightly by style, but the range generally follows a relaxed outer fit with a closer-fitting liner. Check the size guide on each product page for specific measurements — it's the most reliable way to find your fit, especially if you're between sizes. Most styles are available across a full size range to suit different builds.

How can I check coverage before choosing a style?

Head to the individual product page for fit notes, fabric details, and the full size guide. These give you the clearest picture of how each style sits and moves, including the liner length and outer shell cut. If you're unsure between two sizes, the size guide measurements will help you decide rather than guessing by size label alone.

What fabrics are used in the men's 2-in-1 shorts range?

Fabrics vary across the range. Core training styles use a woven construction, with certain styles offering 4-way stretch for unrestricted movement. The Velocity Ultra styles feature a mesh construction designed for a lighter, more breathable feel. Check the individual product pages for the exact fabric composition of each style.

Who designed the men's 2-in-1 shorts?

All styles in this range were designed by Myprotein's in-house design team, developed with training performance and everyday gym use in mind.

How should I care for my 2-in-1 shorts?

Always check the care label on your specific pair, as washing instructions can vary by fabric. As a general rule, washing on a cool cycle and avoiding tumble drying will help preserve the fabric's stretch and structure over time. Avoid fabric softeners — they can affect the performance of technical materials.
