Product Insights
The Firebird Wide-Leg Track Pant by Adidas Originals is a 100% recycled polyester pant that replicates the shiny tricot finish of the classic Firebird material, rooted in the Beckenbauer (1967) and Run-DMC's 1980s hip-hop style, and is certified GRS/RCS as part of adidas's permanent phase-out of virgin polyester, saving 45-85% energy while matching virgin polyester in tensile strength and abrasion resistance. However, buyers report the pants run very large and have an excessively baggy fit even after sizing down one to two sizes, and the 31-inch inseam is too long for anyone under 5'6, often requiring hemming that risks altering the wide-leg shape; care requires machine wash cold on gentle and tumble dry low to prevent pilling. Priced at 100 CAD (with Adiclub points roughly $30), the value sentiment is split, but the pant offers versatility for styling as a trouser or luxury piece and is linked to Run-DMC's smart-casual brand appeal.

User confirms wide leg and finds steep price
I got these wide leg sweats for 30$ after using adiclub points on the Adidas website. 80$ is steep but it's all in the brand you pay for.

Firebird Loose pants run long and have thin material
I recently tried on the Adidas Originals Firebird Loose track pants in two different sizes (M and S), and both of them are way too long in the legs for me. I also find that the fabric of the pants is a bit too thin as the edges of my underwear are visible at the back. I had hoped the pants would be a bit thicker.

Baggy Firebird runs huge, requires tailoring
In case anyone has the same question, and finds this post…they are not even close. I ended up sizing down and purchasing a Medium (I usually wear Large) and I’m still swimming in them. I went to to get them tailored, and they had ti cut off a lot of material. Even a S would be too big. Just fyi.
