Why it works
Brushed Flannel Fabric & Construction

We weave this Mossimo jacket from 100% cotton yarn, then brush both sides of the fabric for softness against your skin. The midweight flannel gives you structure without stiffness — it drapes naturally whether you wear it open or buttoned.

Sizing & Fit for Layering

This jacket runs true to size with a relaxed cut designed for layering. The drop-shoulder seam sits slightly off your natural shoulder line, giving you room to wear a hoodie or chunky sweater underneath without pulling at the armholes.

Sleeve length is designed for average proportions — if you’re between sizes, we recommend sizing up for a looser shacket fit or staying with your usual size for a more structured jacket look. The hip-length hem provides coverage without adding bulk at the waist.

Care Instructions for Flannel

Care Instructions for Flannel

Machine wash your Mossimo flannel jacket in cold water with similar colors. We recommend turning the garment inside out before washing to preserve the color intensity of the plaid pattern.

Tumble dry on low heat or hang to dry — high heat can cause cotton flannel to shrink slightly on first wash. The brushed texture naturally softens over time, and you’ll notice the flannel developing a vintage hand after several washes. The same attention to durability found in our outerwear collection means this jacket holds its shape season after season. Iron on medium heat if needed, though most wrinkles release naturally as the fabric warms to your body.

Perfect weight for fall layering
I ordered this in the red and black buffalo plaid and it's exactly what I wanted. The flannel is soft but still has structure, so it doesn't feel like I'm wearing a baggy shirt. I've been wearing it over hoodies and it fits perfectly without being too tight in the shoulders.

Better quality than expected
The stitching is solid and the buttons feel sturdy — not cheap plastic. I've washed it twice now and it still looks brand new. The brushed flannel gets softer every time, which I love.

Great fit, runs slightly large
I'm usually a medium and the medium fits comfortably with room to layer. If you want a more fitted look, I'd size down. Overall really happy with this purchase.

Lived in this all October
This jacket became my go-to for cool mornings. It's warm enough that I don't need a coat, but not so heavy that I'm overheating by noon. The plaid pattern goes with everything in my closet.

Exactly what a flannel jacket should be
I wanted something that looked like a jacket but felt like flannel, and this nails it. The pockets are actually functional and the sleeves have enough length. Highly recommend.

Soft and comfortable from day one
Didn't need to wash it multiple times to break it in — it was soft right out of the package. The cut is relaxed without being boxy. I wear it at least three times a week.

Questions About Your Mossimo Flannel Jacket

This jacket has a more structured cut than a traditional flannel shirt, with defined shoulders and a slightly longer body length. It’s designed to be worn as outerwear rather than tucked in. The relaxed fit gives you room to layer a hoodie or sweater underneath, while the drop-shoulder seam prevents pulling at the armholes. If you typically wear flannel shirts in a medium, the medium jacket will fit similarly through the chest but with added length and room in the sleeves.

The midweight flannel construction works best for fall and spring temperatures, typically 45-65°F. In winter, it layers well under a heavier coat or over a thermal base layer and hoodie for added warmth. The fabric provides insulation but isn’t thick enough to replace a winter parka in freezing temperatures. Many customers wear it as a mid-layer during winter months.

Cotton flannel can shrink slightly on the first wash if exposed to high heat. We recommend washing in cold water and tumble drying on low heat or hanging to dry. Following these care instructions, you should see minimal to no shrinkage. The fabric is pre-washed during manufacturing to reduce shrinkage, but high dryer heat can still cause the cotton fibers to contract.

We offer this Mossimo flannel jacket in classic buffalo plaid (red and black), navy and green tartan, grey and black check, and burgundy and cream plaid. All colorways use the same 100% cotton brushed flannel construction. Color availability varies by season, with new plaid patterns introduced each fall.

If you plan to wear this jacket primarily over tees and light sweaters, your usual size will give you a relaxed fit with room to move. Size up if you want to layer it over bulky hoodies or thick sweaters for a looser shacket style. The relaxed cut means most customers find their true size comfortable for typical layering. Check the sizing chart for specific chest and sleeve measurements.

The structured silhouette and button-front design make this jacket suitable for casual office environments, especially when paired with chinos or dark jeans and a crew-neck sweater. It reads more polished than a typical flannel shirt due to the jacket cut and patch pockets. For more formal business settings, we’d recommend pairing it with tailored trousers and keeping it unbuttoned over a collared shirt.

We accept returns and exchanges within 30 days of purchase, provided the jacket is unworn with original tags attached. If you’ve tried it on at home and the fit isn’t what you expected, you can exchange it for a different size or return it for a full refund. Shipping costs for returns are covered if the issue is due to a manufacturing defect.
