Product Insights
3" Stretch Cotton Trunk Waist sizing runs S 30–31 in, M 33–35 in, L 36–38 in and XL 39–42 in, with Lacoste advising the smaller size when between two. The body fabric is a light-to-midweight 95% cotton / 5% elastane jersey that is soft and breathable for everyday wear. Care instructions are restrictive: machine wash at 30°C on a very gentle setting, do not bleach, do not tumble dry, lay flat or line dry, and do not dry-clean. The main tradeoff is coverage versus low-profile fit: the low-rise, 3-inch leg keeps fabric out of the way under slim clothing but leaves more thigh exposed and can migrate. Lacoste states that underwear cannot be returned, exchanged or refunded.
Verified claims
- sizing
- Waist sizing runs S 30–31 in, M 33–35 in, L 36–38 in and XL 39–42 in, with Lacoste advising the smaller size when between two.
- fit
- The trunk is a low-rise, fitted cut with a 3-inch (7.5 cm) inseam that ends high on the thigh.
- sizing
- Do not size down to compensate for the short inseam: a smaller waist does not add leg length, and an overstretched leg opening is more likely to migrate.
- comfort
- The body fabric is a light-to-midweight 95% cotton / 5% elastane jersey that is soft and breathable for everyday wear.
- comfort
- The double-layered front adds support and opacity, but that extra layer can retain more heat than a single-layer front.
- construction
- The front is a closed double-layered pouch with no functional fly.
- construction
- The waistband is a branded elastic band made of 78% polyester, 13% elastane and 9% polyamide, chosen for snap-back and logo retention.
- construction
- Leg openings have narrow folded-over hems with visible stitching, and the rear has a center back seam that shapes the seat.
- material
- The 5% elastane gives the cotton jersey stretch and elastic recovery, helping it move with the body and return toward shape instead of bagging out like pure cotton.
- material
- Stretch alone cannot fix a poorly fitting pattern; if the seat bags or the legs ride up, the cut is part of the issue.
- care
- Care instructions are restrictive: machine wash at 30°C on a very gentle setting, do not bleach, do not tumble dry, lay flat or line dry, and do not dry-clean.
- care
- Ironing guidance is restrictive and inconsistent across the supplied care lists: one allows low iron up to 110°C, while another says do not iron or press.
- styling
- The trunk is styled with an all-over small crocodile logo print and a contrasting branded waistband, with Patterned Green as the depicted default, Patterned Blue as an alternate print, and solid Navy/Midnight Blue as the quiet option.
- styling
- Navy/Midnight Blue is the only solid colourway; the two patterned options are more decorative and may show through thin summer fabrics.
- use
- The 3-inch cut suits everyday wear, short shorts and low-impact movement; it offers less coverage and may ride up during high-intensity workouts or longer runs.
- value
- Every size and colourway is priced at 25 CAD, with no upcharge for XL or patterned options.
- variant
- All four sizes are stocked in all three colourways, so fit need not be traded for pattern.
- tradeoff
- The main tradeoff is coverage versus low-profile fit: the low-rise, 3-inch leg keeps fabric out of the way under slim clothing but leaves more thigh exposed and can migrate.
- warning
- Lacoste states that underwear cannot be returned, exchanged or refunded.

Product comparison
Compared within this brand.
| 3" Stretch Cotton Trunk: Choose this if you want a low-rise, fitted cotton trunk with a short inseam of 7.5 cm (3 inches), made from soft stretch cotton jersey (95% cotton, 5% elastane) with a double-layered front and a wide elastic waistband bearing the Lacoste wordmark. It comes in Patterned Green, Patterned Blue, and Navy/Midnight Blue colorways, each in sizes small through extra large, with patterned options featuring an all-over small crocodile logo print. Brand care guidance for its stretch cotton trunks calls for line drying rather than tumble drying, so this pick suits shoppers who don't mind that routine.[1,2,3,4] | 3" Striped-Band Stretch Trunk Cotton: Choose this if you want short, soft cotton-blend trunks: they are made of soft jersey in a 95% cotton, 5% spandex blend with a 3-inch inseam and a low to mid-rise fitted silhouette, double layered at the front with a contoured front pouch seam. The elastic navy waistband has uninterrupted red and white stripes with a white LACOSTE wordmark and a small embroidered crocodile on the left thigh, and one reviewer reports a great fit, describing the trunks as comfortable, soft, and stretchy with a band that does not double over. They come in Grey in sizes medium, large, and extra large, though sizing guidance from the brand (drawn from a similar stretch cotton trunks page) suggests choosing the smaller size if you fall between two.[5,6,7,8,9] | 3" Retro Striped-Waist Trunk Cotton: Choose this if you want a low-rise trunk worn on the hips with short, square-cut legs ending above mid-thigh, made of stretch cotton jersey (95% cotton, 5% elastane) that the retailer describes as very comfortable, with a double-layered front and contoured pouch. It suits shoppers drawn to a retro look, thanks to the navy elastic waistband with red and white stripes, centered LACOSTE wordmark, and embroidered crocodile logo. It comes in White and Navy/Midnight Blue in sizes small to large; note that the comfort description is the merchant's own wording, not an independent verdict.[10,11,12] |
