Your box jump lands clean, but by the third burpee your shorts have hiked up, the liner bunched, and you’re breaking form to adjust. In CrossFit, a fraction of a second spent pulling fabric is a rep lost. The right pair of training shorts should disappear from your awareness entirely, letting you focus exclusively on the clock, the load, and the next movement.
I’m Mohammad Maruf — the founder and writer behind WellFizz. I’ve spent countless hours analyzing fabric blends, liner construction, inseam geometry, and waistband retention systems to determine what actually survives the demands of high-intensity functional fitness.
This guide breaks down the technical specs that separate gym shorts from CrossFit-ready gear, so you can buy with confidence. Whether you prioritize anti-chafe liners, secure pocket layouts, or squat-proof mobility, you’ll find the best crossfit shorts for your exact training style.
How To Choose The Best Crossfit Shorts
CrossFit places unique demands on clothing that typical gym shorts aren’t designed for. Olympic lifts require unrestricted hip flexion, while high-rep box jumps and burpees punish loose liners. You need a short built for range of motion, moisture management, and equipment security.
Liner Construction and Anti-Chafe Design
The built-in compression liner is the defining feature of a CrossFit short. A loose liner allows the legs to rub together during running or creates bunching during squats. The best liners use a tight-knit four-way stretch fabric that moves with the adductors, not against them, and a moisture-wicking finish to prevent friction burns.
Inseam Length and Mobility
A 5-inch inseam offers maximum freedom for pistols and cossack squats but exposes the thigh. A 7-inch version provides more coverage and stays put better on broad-jump landings. Your choice depends on your thigh circumference and whether you prefer the short to end above or at mid-thigh during the bottom of a squat.
Pocket Placement and Security
Standard gym shorts with open side pockets become dangerous during wall balls or handstand holds, dumping your phone or keys. CrossFit shorts need zippered or deeply angled pockets that keep valuables trapped against the leg. A rear zippered pocket is ideal for a locker key or card.
Fabric Weight and Durability
Lightweight fabrics under 100 GSM dry fast but tear easily on barbell knurling or rope climbs. Heavier polyester-spandex blends between 130-180 GSM resist abrasion and hold shape after hundreds of washes. For rope-climb days, a double-weave panel or thicker outer shell is worth the slight weight penalty.

In‑Depth Reviews
1. Anthem Athletics Isoflex Gym Shorts
The Isoflex stands out because Anthem Athletics gives you three inseam lengths in one product line—5, 7, and 9 inches—so you can match coverage to your specific thigh circumference and squat depth preference. Reviewers consistently praise the heavier, thicker fabric that resists abrasion from barbells and maintains its shape wash after wash, a critical detail for athletes who train daily.
The zip pockets are deeply recessed and survive dynamic movements like handstand walks without spilling a phone or car key. At a 5’9″, 180 lb frame, a size Medium offers a snug but unrestricted waist, while the internal drawstring provides backup security during heavy deadlifts or rope climbs.
One caveat: the color shown in product photos for the charcoal option is all black in reality, not a two-tone design. As long as you pick a solid color you like, the fabric density and zipper quality make this the most durable non-lined short in this lineup for serious metcon work.
Why it’s great
- Thick, durable fabric survives thousands of cycles in the wash
- Zip pockets stay closed during inversions and box jumps
Good to know
- Some color options don’t match the listing image exactly
- No built-in compression liner if you prefer the 2-in-1 design
2. Zero Foxtrot Zero Shorts
Zero Foxtrot engineered the Zero Short with a pocket layout that feels deliberately designed for functional fitness: two side pockets, an interior zippered compartment within the right side pocket, and a zippered back pocket that holds a wallet or phone without bouncing during runs. The 5-inch inseam runs slightly flexible (it can sit closer to 5 or 6 inches depending on your drawstring tension), giving you a middle ground between freedom and coverage.
The outer fabric is quick-drying polyester with a matte finish that doesn’t cling when wet, making these shorts equally useful for outdoor running and casual wear. One reviewer with muscular legs noted the cut is intentionally roomy through the quad, so if you prefer a taper, these may feel baggy.
The main frustration is the drawstring length, which hangs to the knees when untied and becomes bulky under a shirt when knotted. A quick trim solves the issue, and the overall pocket utility is unmatched among the unlined options here.
Why it’s great
- Three separate secure compartments including a rear zippered pocket
- Quick-dry material works for gym, run, and swim use
Good to know
- Drawstring is excessively long and needs trimming
- Cut is loose through the thigh, not a compression fit
3. HOPLYNN 5-Pack 2 in 1 Running Shorts
For athletes who train five or six days a week, rotating laundry is a constant pain point. The HOPLYNN 5-pack solves this by delivering five lined shorts for roughly the same cost as two premium singles. Each short features a built-in compression liner, deep front pockets with a small zippered back pocket, and a 2-in-1 construction that eliminates the need for separate underwear.
A reviewer noted the liner stays tight enough to keep everything secure during sports, and the outer fabric is thick yet breathable. The phone pocket fits an iPhone 15 Pro with a case, which is a realistic test for most gym-goers. The shorts are generic in appearance without prominent branding, making them suitable for casual wear as well.
The main adjustment is sizing: a 5’10”, 175 lb reviewer needed a Large despite normally wearing a 32-inch waist, suggesting a size up is necessary for a comfortable fit. A few users noted the inner seams are visible but not irritating. At this per-unit price, the trade-off is negligible for a daily rotation.
Why it’s great
- Five shorts in one purchase — ideal for weekly training volume
- Zippered back pocket adds security for keys and cards
Good to know
- Runs small; order one size up from your regular waist
- Generic design with minimal aesthetic flair
4. CRZ YOGA Mens 2 in 1 Running Shorts 7″
CRZ YOGA has carved a reputation as a Lululemon alternative, and this 2-in-1 short delivers the soft, lightweight feel that runners and CrossFit athletes want at a fraction of the premium price. The 7-inch inseam provides generous coverage for taller athletes (reviewers up to 6’4″ report a good fit), while the built-in liner eliminates the need for compression shorts underneath.
The fabric is quick-drying and breathable, with a smooth hand feel that reviewers describe as comfortable enough for all-day wear from the gym to casual errands. A secure zippered pocket on the right side keeps your phone locked in place during dynamic movements like burpees or tuck jumps.
The liner is the only point of contention: some buyers find it runs slightly large, leading to bunching during deep squats. If you have thinner legs, the liner may not compress enough to prevent movement. For most builds, the combination of durable stitch work and premium fabric feel outweighs this one limitation.
Why it’s great
- Soft, premium-feeling fabric at a mid-range price point
- Zippered pocket secures phone during inversions
Good to know
- Compression liner can feel loose on slim builds
- Limited color palette compared to bigger brands
5. maamgic 7″ 2 in 1 Gym Shorts
Opacity is an underrated spec in CrossFit shorts. During wide-stance sumo deadlift high-pulls or overhead squats, lightweight fabrics can become translucent under tension. The maamgic 7-inch shorts use a thicker, swim-trunk-like material that blocks visibility completely, giving you confidence during wide-range movements. Reviewers specifically note this as a top priority.
The built-in liner is full-length (not a brief) and the outer shell features a discreet internal drawstring that doesn’t show through the fabric. The stretch is generous, and the dark color options hide chalk marks and sweat stains well. A tall, thin reviewer at 6’4″ found the small size fit perfectly, indicating the cut accommodates lean builds.
The liner tension is the divisive factor: some users report it’s not snug enough for long-distance running or high-rep box jumps, leading to chafing. If you use these primarily for lifting and moderate metcon work where thigh friction is less of a concern, the thick, opaque material is a strong selling point.
Why it’s great
- Thick, non-see-through fabric ideal for wide stance lifts
- Quality stitching holds up to frequent machine washing
Good to know
- Liner may be too loose for serious runners or chafe-prone athletes
- Priced slightly above similar mid-range options
6. maamgic 5″ Running Shorts with Compression Liner
If your typical CrossFit session includes more running, double-unders, and bodyweight skill work than heavy barbell cycling, the 5-inch maamgic shorts are worth considering. The shorter inseam maximizes range of motion for pistols, lunges, and gymnastics, while the built-in compression liner prevents thigh chafing during high-repetition running intervals.
The side pockets include inner compartments that securely hold a phone, keys, and the exact gel chews you need for long training sessions. A rear zippered pocket provides a secure spot for an ID or locker key. Reviewers report the fabric stays looking new after 9 months of machine washing and drying, which indicates strong color retention and seam integrity.
The same liner issue appears here as with the 7-inch maamgic model: some users find the compression short not snug enough for sustained running, causing chafing concerns. This seems to depend on individual thigh circumference and stride mechanics. For athletes who prefer a tighter liner, this pair works best for metcons under 15 minutes.
Why it’s great
- Ultra-lightweight fabric moves well for running and gymnastics
- Inner pocket compartments secure small essentials
Good to know
- Liner may not compress enough to prevent chafing on long runs
- Holes in the side mesh show white backing fabric at seams
7. LRD Mens Athletic Workout Shorts 7″
The LRD 7-inch shorts are an entry-level option that prioritizes comfort and soft fabric over pocket security and compression liner features. The outer material is noticeably soft to the touch, and the inner liner is equally gentle, making these a good choice for lighter gym sessions, stretching, and casual wear. Large side pockets are convenient for a phone, but they do show the pocket lining when you sit.
Reviewers note that the shorts fit nicely and feel extremely comfortable for active use, with one user specifically praising the patriotic design on the leg. The adjustable waist tie helps fine-tune the fit if you’re between sizes.
The main drawback is sizing inconsistency: some users report the shorts run smaller than expected, with a higher-than-average inseam cut that might feel shorter than a standard 7 inches. If you are between sizes, sizing up is the safer play. The lack of a zippered pocket means you should avoid carrying valuables during intense dynamic movements.
Why it’s great
- Extremely soft and comfortable for low-impact training
- Adjustable waist tie provides a custom fit
Good to know
- Runs small; order one size larger than usual
- Open side pockets lack security for intense metcons
