Lululemon Swiftly Tech Short Sleeve Shirt (Crewneck)
Lululemon Athletica · Clothing & Accessories > Athletic Apparel

Era / Decade
2010s-2020s. This is a core staple item for the brand that has been produced for over a decade; the narrow tear-away tag suggests a newer iteration (post-2015).
Material
Seamless construction, likely Silverescent technology fabric (Nylon and X-STATIC Nylon/Polyester blend). Known for anti-stink properties and moisture-wicking.
Condition
Good to Very Good. The garment shows some wrinkling and potentially slight discoloration/yellowing toward the bottom hem (though this may be lighting). No visible rips or snags in the mesh venting.
Demand Level
Strong. The Swiftly Tech line is one of Lululemon's most consistent best-sellers with a dedicated following.

Description
Lululemon Swiftly Tech Short Sleeve in White. Features a slim fit, crew neckline, and seamless construction to prevent chafing. Mesh venting is strategically placed in high-sweat zones for breathability. This versatile athletic top is perfect for running, training, or yoga.
Key Features
Brand recognition, Silverescent technology (odor inhibition), seamless construction, thumbholes (if present on long sleeve, though this is short sleeve), and the classic 'Omega' logo typically found on the back neck or hip.
Authenticity Indicators
High confidence. Characterized by the specific tear-away care tag style and the signature knit-in design patterns. Check for the size dot inside the bottom hem or in a small pocket if applicable.
Flaws to Note
Possible yellowing or perspiration stains under the arms or at the hem (common in white athletic wear). Potential 'pilling' in high-friction areas like the chest or where a hydration pack might rub.
Selling Guide
Where to Sell
Poshmark, Mercari, and eBay are the best venues. Poshmark is especially effective for Lululemon due to a highly active brand community.
Selling Tips
Photograph the size dot to prove authenticity and size. Use keywords like 'Silverescent', 'Seamless', and 'Yoga/Running'. Ensure the shirt is steamed or freshly laundered to remove the heavy wrinkling seen in the photo to maximize 'curb appeal'.
