Product Insights
Only & Sons' Minimalist Knit Pant (59 CAD) offers a slim-straight cut with a straight-leg from the knee and stretchy knit at the waist, producing a clean line with minimal break thanks to its lightweight 64% viscose knit (lighter than Mark's thick stretch knit) for a lighter drape. The main tradeoffs: it omits moisture-wicking and odor control features found in performance knits, and requires careful care—wash cold and air dry to prevent pilling and heat damage, iron low with a cloth to preserve the matte finish. At $6 less than the Under Armour Rival Knit, it provides a minimalist, value-driven option for a refined silhouette.
Verified claims
- Silhouette
- Slim, slightly tapered leg; straight-leg from the knee; mid-rise waistband.
- Fit
- The slim-straight cut produces a close-to-body line from knee to hem with minimal break.
- Care
- Machine wash at 30°C on a gentle cycle, do not bleach, and air dry or hang dry rather than tumble dry to prevent pilling and heat damage.
- Weight
- 64% viscose knit yields a lighter drape than the Mark's thick stretch knit.
- Performance features
- Omits moisture-wicking and odor control features found in performance knits.
- Value
- At 59 CAD, it is $6 less than the Under Armour Rival Knit ($65).
- Ironing
- Iron at low heat with a cloth barrier to preserve the matte finish.
- Fabric stretch
- The knit is 64% viscose, 31% polyester, and 5% spandex, so the fabric is stretchy rather than rigid; the spandex provides real give and snap-back recovery rather than a rigid, woven feel.
- Inseam lengths
- Waist sizes 30–38 and inseam are chosen separately: the pant is listed with a 32 in (81.5 cm) standard inseam, plus 34 in (86.5 cm) and 36 in (91.5 cm) length options, so there is no fixed inseam per waist size.
- Pilling prevention
- Turn the pants inside out before machine washing to shield the knit face from friction and reduce pilling.
- Oil stain care
- Pre-treat oil-based stains by dabbing liquid detergent or stain remover on the soiled area and letting it sit for 15 minutes before washing to prevent set-in marks.

| Minimalist Knit Pant Slim Fit: Choose this if you want a slim, slightly tapered knit pant in a soft, stretchy polyester-blend fabric (64% viscose, 31% polyester, 5% spandex) with a smooth matte finish. It has a mid-rise waistband with belt loops and button closure, slanted front pockets, and two buttoned welt back pockets, with a clean finished hem that sits just above the shoes as shown. Note that Grey is only offered in sizes 32 and 34, while Black comes in sizes 30 through 38.[1,2,3,4] | Mark Knit Pant Slim Fit: Choose this if you want a slim, tapered knit pant whose soft stretch fabric is reported to rival sweatpants in comfort for all-day wear, with a clean silhouette that reviewers say pairs well with blazers in business-casual settings. It suits lean or athletic builds and, per customer reviews, men around 5 feet 7 inches tall, and comes in Black, Grey, and Navy/Midnight Blue with the blue colourway made of 64% viscose, 31% polyester, and 5% spandex. Be aware the cut runs smaller than typical slim fits and can feel skin-tight on larger legs, sizing varies between colors (black reportedly fits skinnier than grey or brown), the knit texture reads more jogger than trouser for formal dress codes, and hang drying is recommended since the pants can shrink after a cold wash.[5] | Piqué Weft Pant Slim Fit: Choose this if you want a slim, tapered pant in a stretch knit with a contrasting piqué texture — the shell is 88% cotton, 9% polyester and 3% spandex, with a mid-rise waistband, slanted front pockets, buttoned welt back pockets, and an unsewn cuff hem you can finish to your preferred length. This listing covers the size 30 Ivory/Cream Beige variant. Note that the product photos show small vertical creasing at the knee and upper thigh.[6,7,8,9] |

Received the wrong item.
I ordered slim fit pnts and received a wide led regular fit pair. This seems to happen a lot with online orders with this company. Unfortunate, because the products are decent.
