What Makes Sport-Tek Moisture-Wicking Fabric Different From Cotton?

May 25, 2026 6 min read By Cameron Wells

Quick Answer

Moisture-wicking fabric moves sweat to the surface to evaporate, rather than absorbing it like cotton.
Sport-Tek pieces at Bear Grips use polyester or poly-blend performance fabric for this reason.
It works best for active, sweat-heavy use; cotton pique still wins for soft, office-facing wear.
No fabric surcharge is added to the base price for the performance material.

Frequently Asked Questions

Is Sport-Tek moisture-wicking fabric actually a difference, or is it a marketing word for polyester? It is a real, physical difference in how the fabric handles sweat, and it changes which use cases the shirt actually fits. Here is a plain-language explanation of what the fabric does, and when it matters for a gym, coaching staff, or outdoor business.

How Moisture-Wicking Fabric Actually Works

Cotton absorbs sweat into the fiber itself, which is why a cotton shirt feels heavy and stays wet for a long stretch after activity. Moisture-wicking polyester works the opposite way: the fiber does not absorb moisture, so sweat is pulled along the fabric surface toward the outside, where it can evaporate faster. The shirt stays lighter and dries quicker, which is the entire reason performance apparel brands like Sport-Tek build around polyester and poly-blends instead of pure cotton.

Where Moisture-Wicking Fabric Matters Most

Any activity that produces sustained sweat. Coaching a practice, working a gym floor, or a long outdoor shift.
Hot climates and summer months. The fabric dries faster between wear and after washing.
All-day wear without a change of shirt. A performance tee or polo holds up better across a full 8-hour shift than a cotton equivalent.

Where Cotton Pique Still Wins

Moisture-wicking fabric is not universally better. Office-only staff, indoor customer-facing roles, and anyone who wants a softer, more traditional hand-feel are generally better served by a cotton pique polo like the Gildan Premium Cotton Pique Polo also in the Bear Grips catalog. Matching the fabric to the actual working conditions of the wearer matters more than defaulting to performance fabric for everything.

Which Sport-Tek Pieces Use Moisture-Wicking Fabric

Every Sport-Tek piece in the Bear Grips catalog, the polo, all three moisture-wicking tees, both long sleeves, both quarter-zips, and all three shorts styles plus the skort, uses this performance fabric approach. It is the defining feature of the brand within the catalog, distinct from the cotton-based Bella+Canvas, Gildan, and Next Level lines sold alongside it.

Frequently Asked Questions

Is moisture-wicking fabric the same as dry-fit or performance fabric?

Yes, these are largely marketing terms for the same underlying idea: polyester or poly-blend fabric engineered to move sweat to the surface rather than absorb it like cotton.

Does moisture-wicking fabric cost more?

The base price already includes the fabric type for each piece; there is no separate fabric surcharge added on top.

Is Sport-Tek fabric good for hot climates?

Yes, this is one of its main strengths. It dries faster and feels lighter than cotton in sustained heat.

Should office staff wear moisture-wicking polos too?

Not necessarily. Indoor, low-activity roles are often better served by a softer cotton pique polo, which is also available in the catalog.
