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.
- Compression
30% spandex yields firm compression and four-way stretch that snaps back.
Why this is supported
The 30% spandex content—roughly double that of typical sports bras—delivers compression. A research source states it is
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.
Feel and performance of Dynamiq® fabric — 30_spandex_content. The four-way stretch ensures instant recovery:
lets the fabric move with the body's full range of motion and snap back instantly
Feel and performance of Dynamiq® fabric — four_way_stretch_recovery. The compression comes from the knit's stretch-recovery mechanics rather than abrasive fabric, so the bra stays comfortable against skin for all-day wear.
- Adjustability
Removable foam padding allows fine-tuning support level.
Why this is supported
The removable foam padding adds adjustability. It is noted that it
adds a layer of adjustability that complements the compression fabric
Value compared to other sports bras under $60 — removable_foam_padding, allowing fine-tuning of support without a more expensive bra.
- Exclusive fabric identity
Dynamiq is a trademarked fabric developed exclusively for INNER SELF and sold only at Simons.
Why this is supported
INNER SELF engineered Dynamiq as a proprietary fabric for its Montreal collection.

- Value compared to premium
At CAD 55, Dynamiq's fabric spec — compression, moisture wicking, breathability, four-way stretch — rivals that of $65+ bras from Lululemon or Sweaty Betty.
Why this is supported
The Dynamiq fabric's four technical attributes—compression, moisture wicking, breathability, and four-way stretch—are highlighted in the product research:
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.
Value compared to other sports bras under $60 — proprietary_dynamiq_fabric- Activity suitability
Designed for low-impact activities; may work for jogging in A/B cup sizes.
Why this is supported
The product's Q&A states that
It adds that for A/B cup sizes, it may provide adequate support for jogging, but is not engineered for high-impact running.
For A/B cup sizes, it may provide adequate support for jogging, but it is not engineered for high-impact running.
Does the light support level work well for A/B cup sizes during running, or is it better suited for yoga/walking?The 30% spandex content—double the industry norm—delivers a firm compression typical of higher-support bras, making it suitable for weight training and barre. Additionally, the four-way stretch fabric allows overhead movements without riding up:
lets the fabric move with the body's full range of motion and snap back instantly
Feel and performance of Dynamiq® fabric — four_way_stretch_recoveryThis combination confirms its suitability for both static low-impact activities and dynamic movement.
- All-day comfort
Soft fabric makes it comfortable for extended wear and casual layering.
Why this is supported
The fabric is chosen for comfort:
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.
Feel and performance of Dynamiq® fabric — soft_lightweight_polyester_faceThis supports the bra's use as both a workout piece and a casual layering item.
- Adjustable padding
Removable foam padding lets wearers adjust support without buying a pricier bra.
Why this is supported
The bra includes removable foam padding, listed in the product description. This allows the wearer to fine-tune support and shape, a feature typically found on higher-end models, without needing to purchase a different bra.

- Set styling
A fashion blogger recommends the all-black Dynamiq set as the most flattering monochrome line for any skin tone.
Why this is supported
A fashion blogger states,
The bra and matching biker short are cut from the same compression fabric, creating a smooth, continuous line that mimics a one-piece bodysuit. The racerback and high-waist silhouette highlights shoulders and elongates legs, and the set is available in three colors for different style personalities.

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.
