Running shorts are your first line of defense against chafing, bounce, and overheating on the road. A bad pair can turn a solid 10K into a lesson in regret, while the right pair disappears so completely you forget you’re wearing them.
I’m Mohammad — the founder and writer behind ProteinJug. I’ve spent countless hours analyzing fabric blends, liner compression levels, and pocket placement across dozens of brands to separate the shorts that actually perform from those that just look fast in the product photos.
This guide covers lined vs. unlined, 5-inch vs. 7-inch inseams, and the pocket designs that keep a phone secure without slapping your thigh. My goal is to help you find the best running shorts for men that match your stride, your gear, and the distance you’re chasing.
How To Choose The Best Running Shorts For Men
Most runners buy the first pair that looks decent and then fight with ride‑up, soggy waistbands, and phone pockets that launch the phone mid‑stride. The three decisions below eliminate those problems before you click add‑to‑cart.
Liner or No Liner — That’s the First Fork
Lined shorts (built‑in brief or 2‑in‑1 compression) eliminate the need for separate underwear and drastically reduce chafing if the liner fits snugly. Unlined shorts give you total freedom to choose your own base layer, but you must wear something underneath unless you enjoy a friction disaster. For runs longer than five miles, a well‑fitting liner usually wins.
Inseam Sets Your Stride Range
Five‑inch inseams maximize airflow and leg mobility, ideal for fast training and hot‑weather racing. Seven‑inch inseams offer more thigh coverage, reduce the chance of the hem riding up, and suit runners who prefer a modest cut or have larger quad circumference. Test each by doing a few lunges — any binding means the inseam is too short.
Pocket Volume That Actually Secures a Phone
A zippered rear pocket sized for a modern phone is the gold standard. Slotted side pockets often let the device bounce or slide out during sprints. If you carry a key fob, a small internal zippered pocket in the waistband or liner is a lifesaver. Every product on this list was evaluated on whether it can hold a current‑gen phone without turning into a pendulum.

In‑Depth Reviews
1. Under Armour Men’s Launch Run 7 Inch Unlined Shorts
The Under Armour Launch Run is an unlined short built for runners who want near‑zero weight and maximum ventilation. The 100% polyester woven fabric feels paper‑thin against the skin, and the strategically placed mesh panels dump heat fast enough for hard tempo efforts on humid mornings.
At a 7‑inch inseam, these shorts offer generous thigh coverage without any fabric drag, and the soft knit waistband paired with an internal drawcord keeps everything locked in place. The right‑side internal phone pocket is a rare find in an unlined short — it holds a large smartphone securely against the thigh without bounce, eliminating the need for an armband entirely.
The fabric composition includes at least 90% recycled polyester, which is a solid sustainability nod. Buyers report the shorts hold up well to weekly washing, and the fit runs slightly small, so sizing up by one is a common recommendation. These are the clear first pick for runners who prefer to layer their own base.
Why it’s great
- Ultra‑lightweight, highly breathable mesh construction for hot runs
- Internal phone pocket secures large phones without bounce
- Sustainable build with recycled polyester content
Good to know
- Runs small — consider ordering one size larger
- Unlined, so you must wear separate base layer
2. CRZ YOGA Mens 2 in 1 Running Shorts 7″
The CRZ YOGA 2‑in‑1 shorts are a clear alternative to premium brands, delivering a chafe‑free compression liner and a quick‑dry shell at a mid‑range price. The outer shell is soft and lightweight, while the inner compression short provides enough support to ditch underwear entirely.
A zippered pocket on the liner is the standout feature here — it fits a phone and keys securely without the weight pulling the waistband down. The 7‑inch inseam hits a balanced length that works for running, gym sessions, and casual wear, and the flat‑seam construction minimizes irritation on longer efforts.
Some users note the liner runs slightly large, which can cause bunching during squats, and the color selection remains limited compared to bigger brands. That said, for runners wanting a Lululemon‑style lined short without the premium price, this pair delivers the fit and function that matter most.
Why it’s great
- Compression liner with phone pocket eliminates extra underwear
- Lightweight, quick‑dry fabric suited for sweaty efforts
- Versatile enough for running, gym, and casual use
Good to know
- Liner can bunch on deep squats for some builds
- Limited color variety compared to competitors
3. maamgic Gym Shorts for Men 7 inch Inseam with Liner
The maamgic 7‑inch with liner feels denser and more substantial than typical gym shorts — the outer fabric resembles swim‑trunk material in thickness and opacity, so there is zero see‑through concern even in bright gym lighting or direct sun. The built‑in compression short provides full coverage and a structured fit that stays put during runs.
A zippered pocket is positioned for secure key and phone storage, and the internal drawstring lets you dial in the waist fit independent of the elastic band. Buyers consistently praise the quality feel relative to the price, with many noting it undercuts Lululemon while offering similar fabric heft and stitching detail.
The main caveat is liner tightness — runners with very thin builds may find the inner short lacks compression against slender legs, which can lead to slight fabric pooling at the thigh. For most body types, however, these shorts deliver premium material thickness and a clean silhouette that works for running and lounging alike.
Why it’s great
- Thick, opaque fabric with no see-through risk in any light
- Built-in compression short and zippered pocket for secure storage
- Premium material feel that rivals higher-priced brands
Good to know
- Inner liner may feel loose for very thin legs
- Higher price point within the mid-range category
4. Fabletics Men’s The Fundamental Short 7″
Fabletics designed the Fundamental Short for runners who want a built-in liner that actually stays put — no riding up, no sliding around during dynamic movements. The liner fits snugly without the need for additional compression shorts, and stays in place through both track intervals and weight training.
The 7‑inch inseam balances coverage and mobility, and the ultra‑lightweight, quick‑drying fabric efficiently wicks sweat. Pockets are deep and positioned to hold a phone without bounce, which is a common failure point in cheaper lined shorts. The athletic cut avoids being baggy or restrictive, making the shorts feel tailored for movement.
The main callout is sizing inconsistency: multiple reviews mention the waist runs large, requiring an elastic adjustment or size swap. The fabric is also not the softest straight out of the bag, though it holds its shape well after repeated wash cycles. For runners prioritizing liner security and pocket stability, these are a strong mid‑range option.
Why it’s great
- Built-in liner stays secure without extra compression shorts
- Lightweight, breathable quick-dry fabric for sweaty training
- Pockets hold phone with minimal bounce during runs
Good to know
- Waist can run extremely large — may need sizing down
- Fabric texture is functional but not especially soft
5. New Balance Men’s Sport Essentials Short 7″
New Balance’s Sport Essentials short is the no‑frills entry into lined running shorts. The built‑in brief liner offers basic support and eliminates the need for separate underwear, while the 7‑inch inseam provides standard coverage for runs and casual wear.
The construction is straightforward — a cotton‑blend feel that isn’t ultra‑lightweight but offers enough durability for regular training. Many buyers note these shorts last through several seasons of use, and the fit is consistent with typical New Balance sizing, though a few reviews mention the waist runs slightly small.
The main trade‑off is breathability: the fabric doesn’t wick as aggressively as polyester‑dominant shorts, so it can feel warmer on summer runs. The built‑in liner is also a point of contention for some runners who prefer a less restrictive feel. For a simple, affordable lined short from a trusted brand that covers the basics, this is a solid entry‑level choice.
Why it’s great
- Built-in brief liner for convenient support without extra layers
- Reliable durability for consistent multi-season use
- Fresh design true to the New Balance athletic aesthetic
Good to know
- Fabric breathability is lower than high-performance wicking shorts
- Built-in liner fit may not suit all runner preferences
- Sizing can vary slightly — some reports of running small
6. Under Armour Men’s Armour Heatgear Compression Shorts
The Under Armour Heatgear Compression Short is a second‑skin layer designed to eliminate friction, support muscle, and wick moisture during any distance. The snug compression fit wraps the quads and hamstrings securely, and the Heatgear fabric actively pulls sweat away from the skin to keep you dry.
A side phone pocket is built right into the compression short — a rare feature that holds a large device like the iPhone 16 Pro Max without bounce, even at race pace. Multiple verified reviews confirm a single pair lasts through years of 40‑50 mpw training, including half marathons and full marathons, which speaks to the material durability.
These are not standalone shorts for most runners — they are typically worn under loose running shorts or used as a base layer in cold weather. The compression fit is intentionally tight; sizing up is recommended if you prefer a less restrictive feel. For the anti‑chafe runner who logs volume and hates thigh rub, this is the piece that solves the problem.
Why it’s great
- Snug compression fit eliminates thigh chafing on long runs
- Built-in phone pocket secures large devices without bounce
- Highly durable — survives years of high-mileage training
Good to know
- Compression can be restrictive; size up for a more relaxed feel
- Designed as a base layer, not a standalone short
7. maamgic Mens Workout Shorts 5″ Short Shorts
The maamgic 5‑inch shorts are built with a silky‑soft 86% polyester and 14% spandex blend that offers exceptional stretch and a barely‑there feel. The fabric is unlined, so you will need a base layer, but the soft touch inside and out makes them one of the most comfortable pairs for casual wear or light training.
Pocket design is thorough: two deep front unzippered pockets, a right zippered pocket for keys (though it won’t fit a phone), a small left pocket for contacts or a card, and a rear zippered pocket that accommodates a phone vertically. The 5‑inch inseam keeps the shorts short and breezy, ideal for runners who want full freedom of movement and prefer a shorter silhouette.
The spandex content gives these shorts a form‑fitting stretch that can feel snug on the quads if you carry significant muscle. Buyers consistently love the color range and the buttery texture, but note the lack of a liner means you must plan your base layer. These are a top choice for the runner who values softness and a modern short‑short length.
Why it’s great
- Ultra‑soft 4‑way stretch fabric is among the most comfortable available
- Multiple pocket layout with a rear zippered pocket for phone
- 5″ short length maximizes airflow and stride freedom
Good to know
- Unlined — requires separate base layer for running
- Form-fitting stretch can feel snug if you have muscular thighs
