How to Care for Waffle Knit Loungewear Without Losing Softness

Waffle knit loungewear stays cloud-soft for years when you follow a few simple care rules most people skip.

Updated 24 Aug 2026 5 min read 7 sections

Waffle knit loungewear holds its signature texture and softness longer than almost any other casual fabric, but only if you treat it correctly from the first wash. Get the care wrong and those deep, satisfying squares flatten out, the fabric pills, and the whole set loses its appeal within a season. Here is exactly what to do instead.

Why Waffle Knit Fabric Needs Special Attention

The waffle texture is created by a raised, grid-like weave that traps air between the squares. That structure is what makes a waffle knit set so breathable and warm at the same time. It is also what makes the fabric vulnerable to the wrong laundry conditions.

Heat is the enemy. High temperatures cause the cotton or cotton-blend fibers to contract unevenly, which crushes the raised squares flat.
Agitation breaks down fibers. Heavy spin cycles and rough drum tumbling pull the loops that form the grid, leading to pilling and snags.
Overloading the machine forces garments to rub against each other constantly, which is the fastest way to dull the surface texture.

If you picked up a waffle knit loungewear piece from Harbor & Thorne, check the care label first. Most harbor thorne pieces use a premium cotton-modal or cotton-spandex blend, and those blends have slightly different tolerances than 100% cotton, so the label is your definitive source.

How to Wash Waffle Knit Loungewear Without Damage

Follow these steps every single time and your set will look new for far longer.

Turn the garment inside out. This protects the outer texture from direct friction against the drum.
Use cold water, always. Cold water (30°C / 86°F or below) preserves both the weave structure and any dye in the fabric. Warm water is acceptable for heavily soiled items but keep hot water entirely off the table.
Select the delicate or gentle cycle. Lower spin speeds and shorter agitation times are the single biggest factor in keeping the texture intact.
Use a mild, low-enzyme detergent. Enzyme-heavy detergents are great at breaking down stains but they also break down protein-based fibers like modal. A gentle detergent designed for delicates is the right call.
Skip the fabric softener on the first few washes. Softener coats the fibers and can reduce breathability. After the fabric has been washed a handful of times and the fibers have relaxed naturally, a small amount is fine.
Wash with similar items. Keep your harven sweatpants and waffle pieces together, away from denim, zippers, or anything with hardware that can snag.

As Refinery29 notes, the waffle knit trend has exploded precisely because the fabric is so versatile, but that versatility depends on maintaining the texture through proper care.

Drying: The Step Where Most People Go Wrong

Drying is where the most damage happens, and it is also the easiest step to get right.

Air dry flat whenever possible. Lay the garment on a clean towel or a drying rack in its natural shape. Hanging a wet waffle knit piece causes gravity to stretch it out, especially at the shoulders and hem.
If you must use a dryer, use the lowest heat setting (air-only or tumble-low) and remove the item while it is still slightly damp.
Never wring the fabric. Twist-wringing breaks the raised loops in the weave. Instead, press the garment gently between two towels to absorb excess water.
Avoid direct sunlight for drying. UV exposure fades color and weakens cotton fibers faster than almost anything else.

Storage Tips That Preserve the Texture

How you store waffle knit is just as important as how you wash it.

Fold, do not hang. Hanging stretches the fabric at the hanger points over time. Fold pieces loosely and stack them.
Store in a breathable space. Airtight bags trap moisture and can encourage mildew, especially with natural-fiber blends.
Keep away from rough surfaces. Storing waffle knit next to items like a bordeaux leather good or anything with metal hardware can cause snags if they are pressed together for long periods.
Cedar blocks over mothballs. If you are storing off-season, cedar is gentler on fibers and leaves no chemical odor.

Comparing Waffle Knit Care Versus Other Loungewear Fabrics

Understanding how waffle knit sits relative to other popular loungewear fabrics helps you make smarter laundry decisions across your whole wardrobe.

Fabric	Wash Temp	Dryer Safe?	Pill Risk
Waffle knit (cotton-blend)	Cold	Low heat only	Medium if over-agitated
French terry	Cold to warm	Medium heat	Low
Fleece	Cold	Low heat	High
Ribbed cotton	Cold	Low heat	Medium

The womens waffle knit lounge set category has grown because the fabric genuinely outperforms fleece and standard French terry for year-round comfort, but that advantage disappears if care is neglected.

Which Harbor & Thorne Pieces Need This Care Routine

Not every piece in your wardrobe is waffle knit, but if you have built out a Harbor & Thorne lounge rotation, here are the items where this guide applies most directly.

The waffle knit set is the core piece. The matching top and bottom are cut from the same fabric, so they can be washed together on the same cycle without any guesswork.
The harven sweatpants use a complementary knit construction that responds well to the same cold-water, gentle-cycle approach described above.

Questions

Can I machine wash waffle knit loungewear, or does it need to be hand washed?

Machine washing is fine as long as you use the gentle or delicate cycle with cold water. Hand washing is gentler and ideal for older or more delicate pieces, but a careful machine wash on the right setting will not damage a quality waffle knit set.

Why does my waffle knit set pill after only a few washes?

Pilling is almost always caused by too much friction during the wash or dry cycle. Turning the garment inside out, using a mesh laundry bag, and switching to the delicate cycle will reduce pilling significantly. Washing with rough fabrics like denim is another common culprit.

Is it safe to put Harbor & Thorne waffle knit pieces in the dryer?

Yes, but only on the lowest heat or air-only setting, and remove the piece while it is still slightly damp. High dryer heat is the fastest way to flatten the waffle texture permanently.

How do I restore softness if my waffle knit loungewear has already gone stiff or flat?

Wash on a cold gentle cycle with a small amount of hair conditioner in place of detergent, then air dry flat. This can partially restore fiber softness. Repeating the correct care routine going forward will prevent further stiffening.

Can I wash the waffle knit set top and harven sweatpants together?

Yes, if both are waffle or similar knit constructions they can share the same cold, gentle cycle without issue. Just keep them away from heavier items with zippers or hardware in the same load.
