Frequently Asked Questions
What fabric is the SisFlow™ Flex Sports Jacket made from, and is it stretchy? ＋
The jacket is made from 75% Nylon and 25% Elastane with added Lycra®, giving it four-way stretch that moves freely in every direction without feeling restrictive. The SisFlow™ fabric has a brushed, buttery-soft finish that feels like a second skin during yoga, gym sessions, or everyday wear.
Is the SisFlow™ Flex Sports Jacket true to size, and how does the slim fit run? ＋
The jacket is designed as a slim fit, so it hugs the body closely for a sleek athletic silhouette. If you prefer a more relaxed feel or are between sizes, sizing up one is recommended for extra comfort during high-movement workouts.
What activities is the SisFlow™ Flex Sports Jacket best suited for? ＋
It's designed for yoga, gym training, running, and casual daily wear, thanks to its four-way stretch, breathable mesh back panel, and thumbholes that keep sleeves in place during movement. The stand collar and slim fit also make it versatile enough to wear as an athleisure jacket outside the gym.
Does the SisFlow™ Flex Sports Jacket have pockets? ＋
Yes — it features both a hidden zipper pocket and an inner stash pocket, making it practical for storing your phone, keys, or cards securely during workouts or on-the-go errands.
How should I wash and care for the SisFlow™ Flex Sports Jacket to maintain its shape? ＋
Machine wash cold with like colors, tumble dry on low, and avoid bleaching, ironing, or dry cleaning to preserve the Lycra® elastane's shape-retention and the fabric's soft finish. Following these care instructions helps the jacket maintain its fit and four-way stretch over time.
How does the SisFlow™ Flex Sports Jacket compare to a regular zip-up hoodie for workouts? ＋
Unlike a standard hoodie, this jacket uses performance-grade SisFlow™ fabric with added Lycra® for superior stretch and shape recovery, plus a ventilated mesh back panel for active cooling — features a typical cotton hoodie won't offer. The thumbholes, elastic zipper pull that doubles as a hair tie, and secure pockets also make it more functional for active use.
