Era / Decade
Circa 2018-2021; this specific marl pattern and jacquard logo waistband were hallmarks of the peak Flex collection era.
Material
Nylon, Polyester, and Elastane blend. High-quality seamless knit construction with sweat-wicking properties and 4-way stretch.
Condition
Very Good. The fabric appears to have maintained its shape and the jacquard logo on the waistband is crisp. No immediate signs of pilling in the inner thigh area or elastic fatigue.
Demand Level
Moderate to Strong. While Gymshark demand has stabilized from its 2019 peak, the Flex line remains a staple for gym-goers. Higher demand during New Year resolution periods and summer.

Description
These Gymshark Flex Cycling Shorts feature the iconic seamless marl knit in a burgundy and pink colorway. Designed with a high-waisted, figure-hugging fit, they include the classic contrast contour shading to highlight the physique and a bold jacquard branded waistband. Perfect for gym training, cycling, or athleisure wear.
Key Features
Highly recognizable branding, popular contour shading, seamless technology for comfort, and a 'squat-proof' reputation that maintains value in the second-hand fitness market.
Authenticity Indicators
High confidence. Look for the inner heat-sealed care label (rather than a physical tag) and the specific density of the jacquard knit logo. Counterfeits usually have thinner waistbands and less defined contour shading.
Flaws to Note
Potential for minor pilling at the crotch or inner thighs (common in knit activewear). Check for any 'snags' in the seamless fabric which cannot be easily repaired.
Selling Guide
Where to Sell
Poshmark and Depop are the best platforms for this brand due to their younger, fitness-focused demographic. Mercari is also a strong secondary option.
Selling Tips
Use keywords like 'seamless', 'squat proof', 'high waisted', and 'contour'. Always take a photo of the gusset/crotch area to prove cleanliness and lack of pilling. Mention if the item comes from a smoke-free home.
