Satisfy
Space-O™ Micro-Perforated Short 2.5" Length
A 2.5-inch running short from Satisfy, made for road and trail running with a lightweight, four-way-stretch micro-perforated Space-O™ jersey that provides ventilation, quick drying, and odour resistance. It integrates a Justice™ liner, an elastic waistband with hidden drawcord, a sweat-resistant phone pocket at the rear, and reflective branding. User reviews note the fit is snug, so sizing up is advised, and while the liner is comfortable for some, others report chafing and minimal support.

Product Insights
Satisfy's Space-O Micro-Perforated Short 2.5" Length uses Italian-milled micro jersey (88% polyamide/12% elastane) with precision-punched 4-way stretch, offering a high-fashion aesthetic at $250 CAD. The core promise is premium running style and durability—buyers report lasting over 3 years and multiple marathons—but the tradeoff involves sizing that runs small, a compressive liner with minimal support, and bonded seam seams that can chafe despite anti-chafe design. The removal of side pockets eliminates the original six-gel storage capacity, though a phone pocket in the waistband reduces bounce. Some buyers receive the women's version, causing support issues. Odor control persists after washing, and care requires hand or machine cold wash to preserve micro-perforations.
Verified claims
- Sizing
- Buyers report shorts run small and size up.
- Fit
- The Justice brief liner is compressive but non-restrictive, and the shorts run small enough that many buyers size up.
- Chafing prevention
- An anti-chafe Justice brief, a double waistband that tucks the drawcord away, and bonded outer seams reduce friction points.
- Storage capacity
- Side pocket removal eliminates integrated six-gel capacity.
- Durability
- A marathoner used the Space-O 2.5 through at least three marathons.
- Price positioning
- At $250 CAD, the price reflects high-fashion branding.
- Brand cachet
- Satisfy is the French high-fashion running brand in urban run clubs.
- Fashion-performance balance
- The original design earned praise for carrying six gels easily, but the current revision no longer includes side storage pockets.
- Shell fabric
- Italian-milled micro jersey (88% polyamide/12% elastane) with precision-punched 4-way stretch.
- Sourcing
- Fully European textile chain: Italian-milled shell and French-made Justice liner.
- Construction
- Bonded seams, detachable tag, and double waistband reduce friction and fabric wear.
- Waistband and tag
- Double waistband and detachable tag prevent drawcord and tag chafing.
- Phone pocket
- A sweat-resistant phone sleeve is integrated into the dual-layered elastic waistband and keeps a phone secure, dry, and bounce-free.
- Care
- Hand wash or machine wash cold (30°C) to preserve micro-perforations.
- Odor control persistence
- Odor control remains effective after repeated washing.
- Moisture management
- The Justice liner wicks moisture rapidly and dries exceptionally fast, helping the shorts stay comfortable during sweaty runs.
- Fabric
- The shell is a four-way-stretch perforated fabric milled in Italy.

Edge seam bonding chafing on Space-O 2.5
In the brief format of these 2.5" ones (and the Space-O 5") Satisfy's edge seam bonding is lackluster and can chafe - completely ruining the awesome nature of the fabric.

Space-O shorts run small
I’m usually between a Medium or Large. 6ft 180lbs, usually a 33 waist — I recently purchased space-o shorts in a size large and they fit pretty snug. I’m contemplating trying a pair in xl, which I’ve never worn in any other brand.

Missing pockets in revised version
I'm thinking about grabbing an extra pair or two of the old 2.5" versions that are available in the archive sale just because they still have the side pockets. I've run two marathons in these specifically BECAUSE of the extra pockets for gels and gummies, really feels like a miss getting rid of the storage.

Unsupportive liner on 2.5 shorts
Okay this is wild because i ran yesterday for the first time with my new 2.5 shorts and i experienced the exact same thing LOL. I also thought maybe they gave me the female version or im blessed because my junk was mostly out the side for the run. I think you have to wear underwear with them which is stupid asf because yea that liner is a joke there is zero support.

Durable favorite shorts with great liner
Satisfy’s Space-O 2.5 shorts are by far my favorite running shorts, and I’ve tried quite a number. The true value i think is in the Justice liner, which is a lightweight, thin and form fitting material that just disappears on the skin. I’ve got 3 pairs, 2 of which have held up over 3 years of abuse and still work as new.
