This season, two fabrics are making waves: fleece which is soft, cosy, and insulating, and scuba, which is known for its smoother surface and more body, helping garments that can hold a clean, structured shape.

For home sewers and indie makers, that difference can completely change how a hoodie, pair of joggers, skirt, or dress looks and feels. In this guide, we’ll compare fleece vs scuba by warmth, stretch, texture, breathability, sewing behaviour, and best uses so you can choose the right fabric for your pattern.

Fleece vs Scuba: Quick Comparison

If you just want the key differences at a glance, here’s how fleece and scuba compare across the things that matter most when choosing fabric for a project.

Quick takeaway: Choose fleece when warmth, breathability, and a soft feel are the priority; choose scuba when you want more structure, recovery, and everyday weather resistance.

What Is Fleece Fabric?

Fleece is a soft, insulating knit fabric with a brushed surface that gives it that warm, cosy texture. It comes in a range of weights and finishes, from lightweight microfleece to mid-weight polar fleece and heavier plush or Sherpa styles, so it can feel quite different depending on what you choose.

For sewing, fleece is especially popular for hoodies, sweatshirts, joggers, loungewear, jackets, and other cold-weather layers. It also tends to be fairly easy to work with since it doesn’t usually fray much, though thicker versions can add a bit of bulk at seams.

What Is Scuba Fabric?

Scuba fabric is a smooth, medium-to-heavyweight double knit with plenty of stretch and enough body to hold its shape. It’s most commonly made from polyester and spandex, though you’ll also find nylon, cotton-blend, and scuba crepe versions. That double-knit construction is what gives scuba its slightly spongy feel, clean surface, and structured drape.

For sewing, a scuba style really shines in pieces where you want to stretch without a lot of flop. Think fitted dresses, pencil skirts, structured sweatshirts, zip-up hoodies, joggers, jackets, blazers, and other athleisure styles. It also tends to resist fraying, which makes it a pretty practical choice for clean, modern finishes.

Fleece vs Scuba: How do they differ?

Now that we’ve covered what each fabric is, let’s look at how fleece and scuba compare in the areas that matter most when you’re choosing fabric for a sewing project.

Warmth & Insulation

For outerwear, warmth matters because the fabric needs to help hold body heat while still being comfortable enough to layer and move in. Heavyweight fleece does this especially well thanks to its brushed, lofty surface, which traps more air and provides strong insulation without feeling as heavy as you might expect.

Scuba also offers some insulation because of its dense double-knit structure, but it doesn’t trap as much air as fleece. It tends to feel heavier and more structured, though it does a better job of blocking wind and handling light rain.

• Winner for warmth & insulation: Fleece. The trade-off is that scuba gives you a sleeker shape and better wind resistance, while fleece gives you more actual insulation and breathability.

• Fabric recommendation : Fabric + Flow’s Fleece Knit in Thyme is a 280 GSM cotton-polyester fleece with a smooth knit face and soft fleece backing. It’s a great weight for sweatshirts, pullovers, joggers, and cosy everyday layers without feeling overly bulky.

Structure, Drape, And Silhouette

Fabric structure has a big effect on how a finished garment sits on the body. Scuba has much more body and bending resistance, so it holds clean lines, keeps volume, and can make details like pleats, peplums, collars, and structured sleeves stand out. Fleece is softer and more flexible, so it tends to fall closer to the body and works better for relaxed, slouchy shapes.

• Winner for activewear:  Scuba, especially for fitted pieces that need to bounce back after movement. The exception is stretch fleece with added spandex, which can work well when you want more warmth without giving up too much flexibility.

• Fabric recommendation: Fabric + Flow’s Scuba in Radiant Orchid is a 320 GSM cotton-polyester-spandex knit with four-way stretch and plenty of structure. It’s especially well suited to fitted dresses, skirts, peplum styles, jackets, and other projects where you want the fabric to hold a clean shape.

Stretch, Recovery, and Movement

Stretch tells you how far a fabric can comfortably extend, while recovery is how well it returns to its original shape afterwards. Both matter when you’re sewing fitted pieces or anything that needs to move with the body, because a fabric can stretch well but still lose its shape over time.

Scuba generally has more horizontal stretch and much better recovery thanks to its spandex content and dense double-knit structure. Standard fleece usually has less stretch and relies more on the give in the knit itself, so it works better in relaxed or oversized shapes.

• Winner for activewear:  Scuba, especially for fitted pieces that need to bounce back after movement. The exception is stretch fleece with added spandex, which can work well when you want more warmth without giving up too much flexibility.

• Fabric recommendation: Fabric + Flow’s Scuba in Pearl Luxe blends cotton and polyester with 5% spandex, giving it flexibility while keeping that smooth, structured scuba finish. At 320 GSM, it’s a good option for fitted skirts, structured joggers, pullovers, and other pieces where both movement and shape matter.

Moisture Wicking & Breathability

Moisture wicking and breathability both matter when you’re sewing something meant to handle sweat, but they’re not quite the same thing. Fleece has a more open structure, so air and moisture vapour can move through it more easily, while polyester fleece also tends to dry quickly once it gets damp. That makes it a strong option for active cold-weather layers where you want warmth without feeling too stuffy.

Scuba can move moisture across its smooth surface, but its dense double-knit construction doesn’t breathe as freely and can trap more heat during harder workouts.

• Winner for exercise:  Fleece, especially for hiking, running layers, and other active cold-weather use. For day-to-day wear, scuba gives you a smoother, more structured look when maximum breathability isn’t the priority.

• F abric recommendation: Fabric + Flow’s Fleece Knit in Light Melange Grey is a 280 GSM cotton-polyester fleece with a soft fleece backing and gentle four-way stretch. Its breathable warmth makes it a comfortable pick for pullovers, sweatshirts, joggers, and casual layers you’ll actually want to move around in.

Water and Weather Resistance

For light rain and wind, scuba has the edge because its dense double-knit structure creates a tighter barrier against the elements. Light drizzle may bead on the surface for a short time, and it does a better job of blocking wind than standard fleece. That makes scuba a practical option for transitional outerwear like bombers, structured hoodies, and lightweight jackets.

Fleece handles damp, chilly conditions differently. Its fibres resist absorbing much water and it can keep insulating when slightly damp, but the open, fluffy structure doesn’t block rain or wind very well on its own.

• Winner for weather resistance: Scuba. The trade-off is that fleece is usually warmer and more breathable, while scuba gives you a denser layer for breezy, transitional weather. Neither fabric is waterproof, so for sustained rain, you’ll still want a proper outer shell.

• Fabric recommendation: Fabric + Flow’s Scuba in Crème is a smooth, structured scuba that works nicely for transitional pieces like zip-up hoodies, lightweight jackets, and other clean-lined outer layers. Just keep in mind that it’s a fashion scuba rather than a waterproof shell fabric.

Fleece & Scuba Style Directions: Dress up, Dress Down, Mix fabrics

Here’s how to flex these fabrics in your wardrobe so pieces feel more than just “comfy clothes.”

Pro Tips to Style Fleece and Scuba

These little styling choices can make a big difference, especially if you’re mixing fleece and scuba or trying to make a simple athleisure piece feel more intentional.

• To tone down a bold red or electric color, balance with neutrals in bottom/hats/shoes.

• Use monochrome layering (e.g. different textures of similar hue) to make the look more cohesive.

• For transition seasons, choose lighter-weight fleece or thinner scuba so the layering doesn’t bulk.

• Add small details (contrast piping, colour-blocking panels, tonal zippers) to elevate a basic fleece or scuba set.

Fleece and scuba are both knits, but they behave pretty differently at the machine, so a few small adjustments can make sewing them much easier.

• For fleece, use a good ball‑point needle or stretch knit needle; serger or stretch stitches for seams.

• For scuba, pay attention to edge finishing (it doesn’t fray much, but sometimes can have bulk). Use a walking foot or stretch stitch so seams lie flat.

• Consider stabilizing shoulders or necklines with lightweight elastic or stay tape, especially in scuba to prevent distortion.

• When mixing fabrics, remember they may need different seam allowances or handling care.

• Always make a muslin (or test piece) if mixing heavy scuba and lighter fleece so proportions and drape work.

FAQs about Fleece vs Scuba

What are the disadvantages of fleece?

Fleece is warm, soft, and easy to sew, but it isn’t very wind- or rain-resistant on its own. It can also feel bulky in heavier weights, and some synthetic fleece can shed microfibres during washing. For care, wash it gently and follow the fabric supplier’s instructions to help maintain its loft and finish.

Does scuba fabric keep you warm?

Yes, scuba fabric provides some warmth because its dense double-knit structure helps trap a small layer of air and block wind. It usually isn’t as insulating as heavyweight fleece, though, so it works better for transitional weather, structured layers, or garments worn over a lighter base layer.

Can fleece and scuba be combined in one garment?

Yes. They can work well together when you want to mix softness and structure, such as fleece for the body of a hoodie and scuba for panels, collars, or other shaped details. Just compare the weight, stretch, and recovery of both fabrics first so one section doesn’t pull or distort the other.

Are fleece and scuba suitable for half-zip hoodies?

Yes, both work well for half-zip hoodies, but the zipper should match the fabric. A flexible nylon coil zipper is a good choice for scuba, while thicker fleece can handle a sturdier moulded plastic zipper. Fabric + Flow’s closed-end zippers are a handy option for this type of project, especially when you want a clean, low-profile finish. Stabilizing the zipper opening before sewing will also help prevent stretching and keep the front looking neat.

Fleece or Scuba? Make It Your Own

At the end of the day, the better fabric comes down to the kind of garment you want to make. Go with fleece when you want warmth, softness, and easy everyday comfort, or choose scuba when you’re after a cleaner shape, more structure, and a polished athleisure look.

Whichever direction you take, Fabric + Flow has the fabrics, trims, and zippers to help bring the whole project together. Pick your pattern, choose the fabric that fits the look and feel you’re after, and make something you’ll actually want to wear on repeat.
