Product Insights
The Dynamiq® Racerback Sport Bra ($55, INNER SELF) delivers premium-level compression and four-way stretch via its exclusive trademarked fabric, rivaling $65+ bras from Lululemon or Sweaty Betty. Designed for low-impact activities (yoga, walking, daily errands) and all-day comfort, it features removable foam padding for adjustable support, a stay-put fit that prevents ride-up, and a flattering black colorway that creates a smooth monochrome line when worn as a set. The tradeoff: its support is optimized for low-impact use, though it may suit jogging for A/B cup sizes.

Deep Research
Feel and performance of Dynamiq® fabric
- The Dynamiq blend's 30% spandex content is roughly double the elastane found in typical sport bras (10–15%), producing a firm, body-hugging compression that delivers a noticeably more 'held-in' feel than other light-support options—without relying on thick, stiff panels.
- The four-way stretch, empowered by the high spandex count, lets the fabric move with the body's full range of motion and snap back instantly, ensuring the racerback maintains its fit through overhead reaches and dynamic side-to-side movements without riding up or losing shape.
- Dynamiq is a trademarked fabric developed exclusively for INNER SELF's Montreal collection and sold only through Simons, so its compression-to-softness balance and wicking behavior are purpose-tuned to the brand's activewear vision—giving the bra a curated, design-forward identity that sets it apart from generic private-label sportswear.
- With its 70% polyester face described as soft and lightweight, the compression comes from the knit's stretch-recovery mechanics rather than from abrasive fabric, meaning the bra stays comfortable against skin for all-day wear under casual clothing, not just during workouts.
Styling the matching biker short set
- Choosing the black set leans into the kind of all-black biker-short-and-sports-bra pairing that Malikah Kelly highlights as 'the most flattering' and suitable for any skin tone, creating a streamlined, low-stakes look that can be dressed up with accessories without competing with the rest of the outfit.
- Because both the bra and its matching short use the same compression-driven Dynamiq fabric, wearing them together produces a smooth, continuous line that mimics a one-piece bodysuit — a silhouette that reads as a cohesive outfit rather than separates thrown together.
Value compared to other sports bras under $60
- Four-way stretch allows the fabric to extend and recover in all directions, so it won't restrict shoulder or torso rotation during side-to-side movements; this puts it on par with premium athleisure brands that market multidirectional stretch as a key selling point.
- While removable padding can be found on many bras, at this price it adds a layer of adjustability that complements the compression fabric, allowing the wearer to fine-tune support without stepping up to a more expensive model.
- The named Dynamiq® fabric calls out four technical attributes—compression, moisture wicking, breathability, and four-way stretch—a multi-function fabric story that, at CAD 55, rivals the marketing of $65+ bras from Lululemon or Sweaty Betty, giving this bra a spec-forward identity unusual for its price tier.
- With 30% spandex, this bra contains substantially more elastane than the 15–20% common in competing low-impact bras from Nike and Under Armour, translating to a snugger, more durable compressive fit that holds its shape after repeated wear.
The INNER SELF brand and its Montreal collection
- INNER SELF RUNNING INC. filed a Canadian trademark for the brand name in December 2025 under class 25 for apparel, signaling a long-term commitment to intellectual property and a defensible brand identity — for a buyer, this indicates the brand is building a permanent presence in the activewear market rather than operating as a temporary pop-up label.
- INNER SELF's entire identity is built around the mission to 'empower runners to break boundaries and embrace their freedom' — a manifesto that positions the brand as a vehicle for personal liberation through running, giving this bra a narrative depth rarely found in generic activewear sold alongside basic cotton tanks.
- With a company size of 2-10 employees and no external funding, INNER SELF remains a hands-on, founder-led label — Gabriel Vigneault is listed as Owner/Designer, meaning a single creative vision drives every product; this boutique scale often correlates with more deliberate design choices and a closer feedback loop with the running community than mass-market competitors can offer.
- The Dynamiq Racerback Sport Bra is part of INNER SELF's Montreal collection created exclusively for Simons — for a nascent brand, achieving a department store exclusive implies a level of production rigor and market confidence, and the 'Montreal collection' naming suggests a curated, regional identity that adds storytelling depth beyond a standard retail buy.
- INNER SELF engineers its own performance textiles — the bra's Dynamiq fabric is a compressive stretch material designed for support and recovery, while the brand's shorts use AirGrid, an ultralight 95 GSM perforated fabric built for maximum airflow — the use of named, purpose-specific fabrics across categories signals a technical, R&D-driven brand rather than a fashion-only label.

Q&A
2 answered- What is the best way to care for the Dynamiq fabric to maintain its moisture-wicking and compression properties?
- To maintain the moisture-wicking and compression properties of the Dynamiq fabric (70% polyester, 30% spandex), wash in cold water on a gentle cycle and avoid fabric softeners, which can clog the fabric's pores. Hang or lay flat to dry—do not use a dryer or iron, as heat can damage the elastic fibers. These care steps help preserve the garment's performance over time.
- Does the light support level work well for A/B cup sizes during running, or is it better suited for yoga/walking?
- This bra is designed specifically for low-impact activities like yoga, walking, or weight training. For A/B cup sizes, it may provide adequate support for jogging, but it is not engineered for high-impact running. Reviewers of similar low-support bras often note that for running, a medium- or high-impact bra is generally recommended to minimize bounce and discomfort.
