Product Insights
The Preppy Retro Trackpant from Le 31 blends a structured, straight-leg fit with a satiny piqué jersey that channels air and wicks moisture, offering both breathability for active wear and a smart-casual sheen. True to size with an elastic waist, it resists bagging and pilling while maintaining a smooth drape. The brown colorway pairs with cream, blue, and olive for an autumnal preppy palette, and side stripes elongate the leg. Made from 55% reprocessed polyester and 45% organic cotton, it balances retro-luxe style with durability, though the matching track jacket is sold separately for a full tracksuit.

Deep Research
How to style preppy retro trackpants today
- Brown in a satiny finish acts as a warm neutral anchor; paired with cream cable-knit sweaters, light blue oxfords, or tonal olive outerwear, it deepens the outfit's autumnal preppy palette without clashing with accent colors.
- The straight fit falls cleanly over footwear without bunching, so it works equally well with minimal white sneakers or chunky retro runners — a silhouette that avoids the tapered jogger look and keeps the retro vibe authentic.
- The fabric's subtle sheen and heavier weight elevate the trackpant beyond loungewear, allowing it to hold its shape when styled with a button-down oxford and leather loafers for a sportif preppy smart-casual look.
- The athletic-style striped inserts act as a vertical line that elongates the leg, so pairing the pants with a tucked-in polo or crewneck sweater draws the eye cleanly downward for a vintage tennis or track-inspired silhouette.
- The matching jacket turns the trackpant into a complete preppy track suit; wearing both together creates a deliberate retro-luxe statement that requires no additional coordination, making it the easiest route to the trend.
How the piqué jersey fabric wears and breathes
- The combination of polyester's fiber strength and the piqué knit's textured surface reduces the formation of abrasive pills that typically mar flat cotton jersey pants after repeated washes.
- The satin face smooths the piqué texture into a fluid, low-friction surface that glides over the leg without clinging, giving the straight-cut silhouette a more polished, less athletic drape.
- Organic cotton absorbs excess perspiration while the polyester component wicks it outward and shortens evaporation time, keeping the fabric drier against the skin and faster to air-dry than 100% cotton sweats.
- At a comparable fabric weight, piqué jersey allows significantly more airflow than interlock or fleece because its waffle-like raised loops create channels that break up the insulating still-air layer, reducing the clammy, heat-trapping feel.
- Recycled polyester fibers intertwine with the organic cotton to increase tensile strength and recovery, so the knees and seat resist permanent bagging even after extended wear and hang-drying.
What the straight fit looks like on and how it compares
- A straight cut — without the inward taper of a jogger — keeps the leg opening wide enough to fall cleanly over loafers, derbies, or chunky retro sneakers without bunching, making the pant work for footwear that requires a trouser-like break.
- The heavy, subtle-sheen fabric has enough body to resist collapsing around the calves, so the straight silhouette remains structured through the day rather than turning slouchy.
- Continuous contrast stripes run the full length of each leg, creating a clear vertical design line that elongates the silhouette and references classic 1970s trackpants.
Le 31’s design approach and sustainable materials
- Tagged as preppy, retro, and casual, the straight-fit silhouette with elastic comfort waist and sporty stripe detailing channels the relaxed, collegiate aesthetic that has resurged in recent seasons, situating this trackpant within a specific fashion conversation rather than as generic loungewear.
- Le 31 is the signature private label of Simons, a family-run Canadian department store with roots dating back to 1840, giving these trackpants a design lineage that prioritizes trend-aware, in-house development over mass-market sourcing, which often translates to better fit and aesthetic cohesion at this price.
- The thick piqué knit provides body and structure that resist sagging, while the satin finish adds a subtle luster that elevates the pants above standard fleece, enabling them to transition from casual days to dressed-down evenings more convincingly than typical sweatpants.
- The side-stripe inserts reference vintage track-and-field heritage while the coordinating zip jacket (sold separately) turns the trackpant into part of a full retro tracksuit, signaling Le 31's emphasis on head-to-toe styling and the kind of cohesive collection thinking more common in higher-tier fashion brands.
- The blend of organic cotton—cultivated without synthetic pesticides—and recycled polyester derived from post-consumer plastic waste gives the satiny piqué jersey a reduced environmental footprint while maintaining the garment's sturdy, structured hand, making it a conscientious choice for everyday wear.

Q&A
3 answered- How does the fit compare to other Le 31 trackpants? Is the waist true to size given the elastic band?
- The Preppy Retro Trackpant has a straight fit with an elastic comfort waist, so it generally fits true to size. Compared to other Le 31 pants like the Faded French Terry Joggers (also with elastic waist), this one has a similar waistband approach but a slightly more structured satiny piqué fabric. We recommend sticking with your usual size.
- What are the recommended washing instructions for the satiny piqué jersey material?
- We recommend machine washing cold on a delicate cycle and turning the garment inside out. Do not use fabric softener, as it can cause pilling. Hang to dry in the shade and avoid tumble drying. A low iron can be used if needed.
- Is the satiny piqué jersey smooth on the outside and textured on the inside, or is it the same on both sides?
- The satiny piqué jersey has a smooth, slightly lustrous outer surface with a subtle textured pattern, while the inside is likely softer and less textured due to the satin finish. It is not identical on both sides.
