The wrong trail running short turns a technical descent into a misery of chafing, fabric grab, and pocket toss. You need a short that sheds water fast, hugs your quad without squeezing, and holds a bar or phone without bouncing on every root and rock. The difference between a good run and a great run often comes down to that 7-inch inseam and the quality of the built-in liner.
I’m Mohammad — the founder and writer behind ProteinJug. I’ve analyzed over 100 pairs of athletic shorts, comparing liner construction, fabric weight in GSM, pocket geometry, and seam placement across budget, mid-range, and premium trail models to find what actually works on singletrack.
After evaluating dozens of options, I’ve settled on seven models that balance durability, moisture management, and freedom of movement for the trail. This guide breaks down the specs that matter so you can pick the best trail running shorts for your next long run.
How To Choose The Best Trail Running Shorts
Trail running shorts face different demands than road shorts — you need abrasion resistance against brush, water resistance for splashes, and pockets that don’t dump your gear when you roll an ankle. Here are the three specs that make or break a trail short.
Liner Type and Fit
Built-in liners range from loose mesh briefs to snug compression shorts. For trail use, a compression-style liner (often labeled 2-in-1) provides better thigh support and reduces friction on long descents. Brief-style liners can cause chafing when dirt and sweat mix. Check reviews for liner tightness — a liner that bunches or slides is the top complaint among trail runners.
Pocket Security
Standard front pockets work on pavement but fail on steep terrain. Look for at least one zippered pocket positioned on the back or side seam to secure a phone, key, or energy bar. The pocket should sit snug against your body — flapping or deep pockets cause gear bounce that throws off your stride. Some models include a dedicated phone sleeve inside the liner for zero-movement carry.
Fabric and Water Resistance
Trail shorts need a fabric that dries quickly after creek crossings or heavy sweat. Lightweight polyester blends with a DWR (durable water repellent) finish shed light rain and spray. Avoid 100% cotton or heavy cotton-poly blends — they absorb water and stay wet, adding weight and causing chafing. Aim for a fabric weight of 100-140 GSM for the best balance of durability and breathability on trail.

In‑Depth Reviews
1. MudGear Men’s Freestyle Running Shorts
The MudGear Freestyle is purpose-built for muddy obstacle racing and technical trail runs. Its lightweight, quick-drying fabric sheds water and mud after creek crossings or sweat-soaked climbs. The 7-inch inseam provides enough coverage for brush without restricting stride, and the back zipper pocket fits a phone securely with zero bounce — a critical feature for trail runners who need hands-free carry.
The inner brief liner has drawn mixed feedback. Most users find it comfortable and supportive for races and gym leg days, but a few report the “panty” style liner feels restrictive and have removed it. For obstacle course racers who hit water and mud regularly, the fast-dry performance and durability after repeated wash cycles make this a top pick.
Owners consistently praise the shorts for holding up through Spartan Races and Tough Mudder events, with no rips, tears, or fading after months of abuse. The drawstring is notably long, and pocket size varies by color — the black version has a 50% larger pocket than the grey, so check your color choice if you carry a larger phone.
Why it’s great
- Fast-drying after mud and water exposure
- Zipper pocket stays secure during technical trail sections
- Durable stitching survives obstacle races
Good to know
- Inner brief liner not preferred by all runners
- Pocket size varies by color
- Drawstring length may need trimming
2. THE NORTH FACE Men’s Wander Short 2.0
The North Face Wander 2.0 is designed for hot summer trail days and water-adjacent runs. The DWR finish sheds light rain and splashes, while the moisture-wicking fabric pulls sweat away from your skin to prevent chafing on long, humid climbs. The elastic waistband with internal drawcord offers a customizable fit without digging into your hips.
This short runs small — multiple verified buyers suggest sizing up if you are between sizes. The fabric is lightweight and quick-drying, making it a favorite for creek crossings and post-swim runs. The forest olive color has been spotted at deep discounts, adding strong value for those who catch a deal.
While the Wander 2.0 excels in hot conditions, the lack of a built-in compression liner means you will need separate base layers or briefs for chafe protection on longer runs. The DWR coating holds up well through multiple washes but is not intended for heavy rain exposure — it is best suited as a summer trail short for day hikes and short to mid-distance runs.
Why it’s great
- DWR finish handles light rain and spray
- Lightweight, quick-drying fabric ideal for hot conditions
- Elastic waist with internal drawcord fits comfortably
Good to know
- Runs small — plan to size up
- No built-in compression liner
- DWR coating is not heavy-rain rated
3. HOPLYNN 5 Pack Mens 2 in 1 Running Shorts
The HOPLYNN 5 Pack delivers exceptional value for runners who need a rotation of trail-ready shorts without a premium price tag. Each pair features a built-in compression liner that eliminates the need for separate underwear, plus deep front pockets and a small back zipper pocket that fits an iPhone 15 Pro with case. The fabric is thick enough to avoid show-through during deep squats but breathable enough for warm-weather runs.
Buyers report the shorts run slightly small — a 5’10”, 175-pound runner with a 32-inch waist needed a size Large for a comfortable fit. The seams are internal, which some users find slightly irritating, but the majority say the seams are not noticeable during movement. The generic unbranded look appeals to those who prefer minimal branding.
For the price of a single premium short, you get five pairs that perform well for running, gym workouts, and casual wear. The compression liner is snug without being restrictive, and the fabric dries reasonably quickly after washing. If you are building a trail running wardrobe on a budget, this pack is the smartest entry point.
Why it’s great
- Five pairs at the cost of one premium short
- Deep front pockets and a zipper back pocket
- Compression liner prevents chafing during runs
Good to know
- Runs small — size up for proper fit
- Internal seams may irritate sensitive skin
- Fabric is slightly thick for hot, humid days
4. Eddie Bauer Mens Rainier Short
The Eddie Bauer Rainier Short is a versatile option that bridges trail running, hiking, and active travel. Its stretch fabric allows a full range of motion on technical terrain, while the durable water-repellent finish handles light precipitation and dewy morning brush. The multiple pockets — including secure zippered options — make it a practical choice for runners who carry a phone, keys, and a snack.
Fit is slightly sporty and true to size, though some users note the waistband is not adjustable beyond the internal drawstring. The fabric is lightweight and cool, but the stretch is moderate — not enough for deep squats without seam stress. The 7-inch inseam falls at a comfortable mid-thigh length that avoids the too-long or too-short extremes.
After a year of regular use, the Rainier Short holds its shape, color, and water resistance. The front pockets are deep enough for a cased iPhone but not oversized for larger phablets. For runners who want one short that transitions from trail to travel to casual wear, this is a strong, durable choice.
Why it’s great
- Stretch fabric allows full range of motion
- DWR finish handles light rain and brush
- Durable construction survives repeated wash cycles
Good to know
- Moderate stretch — not great for deep squats
- Waistband is not adjustable side-to-side
- Pockets could be deeper for larger phones
5. CRZ YOGA Mens 2 in 1 Running Shorts 7″
The CRZ YOGA 2 in 1 shorts deliver strong value for runners who want a compression-liner short without spending premium money. The built-in liner prevents chafing and eliminates the need for separate underwear, while the flat seams reduce irritation on longer runs. The phone pocket inside the liner keeps your device secure and bounce-free — a feature that usually costs much more.
Fit is generally true to size, with a 5’10”, 175-pound runner fitting well in a medium. The 7-inch inseam runs slightly longer than standard, which works well for taller runners with thick thighs. The fabric is lightweight, quick-drying, and breathable, making these shorts suitable for everything from trail runs to gym workouts to casual wear.
Durability is a highlight — multiple users report the shorts survive numerous wash and dry cycles without fading or seam failure. The limited color selection is the main downside, and some users wish for a back pocket. For runners who want a reliable 2-in-1 short at a budget-friendly price, the CRZ YOGA is a proven performer.
Why it’s great
- Compression liner prevents chafing on long runs
- Phone pocket inside liner for bounce-free carry
- Durable fabric survives repeated wash cycles
Good to know
- Limited color selection
- No back pocket for extra storage
- Liner may bunch during squats
6. maamgic Gym Shorts for Men 7 inch Inseam with Liner
The maamgic 2 in 1 shorts offer a thicker, more substantial fabric that feels closer to swim trunks than standard running shorts. This added thickness means zero show-through during deep squats or lunges, but it also reduces breathability on hot, sweaty runs. The 7-inch inseam with a full-length compression liner provides good coverage and support for gym workouts and shorter trail runs.
The liner has drawn mixed reviews — some users find it not snug enough, raising chafing concerns for longer runs, while others appreciate the stretch and fit. The zipper pocket is large enough to secure a phone and keys. The brown/black color option hides stains well, making these shorts practical for muddy conditions.
Build quality is consistently praised for the price point, with strong stitching and a modern aesthetic that works both in the gym and on the trail. However, the liner issue makes these shorts better suited for medium-mileage runs and gym sessions rather than ultra-distance or technical trail use where liner security is critical.
Why it’s great
- Thick fabric eliminates show-through during squats
- Zipper pocket securely holds phone and keys
- Good build quality for the price
Good to know
- Liner not snug enough for some — potential chafing on long runs
- Thick fabric reduces breathability on hot days
- Limited color options
