| Train Flex Micro-Perforated Sleeveless T-Shirt: Choose this if you want a sleeveless training tank in a stretchy recycled polyester blend (55% polyester, 45% recycled polyamide) with soft, quick-dry microfibre and strategic micro-perforated zones for breathability. It suits workouts where a close-fitting crew neck, wide armholes, seamless construction described as providing greater comfort, and a relaxed, straight cut with full coverage to the hips matter. It comes in sizes Small to X-Large in Slate Grey and Blue, with a subtle heathered knit look and a low-contrast tonal logo on the chest.[1,2,3] | Performance Tank Top: Choose this for a functionality-first tank top with a regular fit and zero-feel comfort, featuring a quick-dry, tear-resistant knit on the front and breathable jersey at the back. It is designed with thermosealed seams to prevent friction and offers premium performance through its mix of materials. Note that despite being marketed with recycled content, the composition includes spandex in both the front and back panels.[4] | Core-T Tee: Choose this if you want a lightweight, ultra-breathable tee for running, sports, or everyday wear, made from stretch microfibre jersey of 92% recycled polyester and 8% spandex with a full micro-perforated style. The regular, classic cut is a short-sleeve crew neck with a relaxed straight cut that falls below the waist on the pictured model, and it comes in Black in sizes small to X-large. On positions it as comfortable and never clingy and engineered for all seasons, though those are brand statements rather than reported outcomes.[5,6,7,8] |
