Get your MagnaFlow hoodie and t-shirt fit right the first time, then keep them looking sharp with a simple wash-and-dry routine built for car apparel.

Quick answer

Measure a sweatshirt or tee you already like, compare those numbers to the size chart, and size the hoodie for the layer you'll wear underneath. Then wash cold and hang dry to protect the print and the fleece.

Why hoodie sizing and t-shirt fit need different approaches

A hoodie and a t-shirt are not sized the same way in practice. The MagnaFlow Flow Stamp Hoodie is cut with a classic fit and a generous feel, so it leaves room for a shirt underneath without looking oversized. A t-shirt sits against the body, so its fit is decided almost entirely by chest and length.

That means you can comfortably wear the same letter size in both and still get two different looks: a relaxed hoodie and a closer tee. If you want a matched, trimmer look across both, size down in the hoodie rather than up in the tee.

Where car apparel care goes wrong

Most premature wear on printed gear comes from heat and agitation, not from wearing it. Hot water, a hot dryer, and a heavy load all stress the cotton face and the print. Treat the hoodie and tees as delicate-ish everyday items: cold water, a gentle cycle, and air drying solve most problems before they start.

The fleece blend in the Flow Stamp Hoodie has a 100% cotton face, which is what gives it a soft hand and takes print well. That face is also the part most affected by high dryer heat, so air drying protects both the feel and the graphic.

Steps to size and care for your MagnaFlow gear

Measure a hoodie you already wear: Lay a favorite hoodie flat and measure pit-to-pit and body length. Compare those numbers to the size chart rather than guessing from the letter on the tag. If you're between sizes and plan to layer, choose the larger size.
Choose your t-shirt fit by chest, not by habit: For MagnaFlow t-shirt fit, measure your chest and match it to the chart. If you want a closer fit, stay true to size; if you prefer room to move, go up one. Check sleeve length too, since a tee that's right in the chest can still be short in the sleeve.
Decide on a zip-up layer separately: A MagnaFlow zip-up jacket is worn over other clothes, so size it for the thickest shirt you'll layer under it, not for your bare chest measurement. Try the zip-up on over a hoodie before removing tags if you plan to wear it as an outer layer.
Wash cold on a gentle cycle: Turn the hoodie and tees inside out, close the zipper on any zip-up, and wash in cold water on a gentle cycle with like colors. Skip fabric softener on fleece; it coats the fibers and reduces softness over time.
Air dry to protect print and fleece: Hang or lay flat to dry instead of using a hot dryer. If you must tumble, use the lowest heat setting and remove items while slightly damp. Never iron directly over a printed graphic; press inside out on low if needed.
Store folded, not on a wire hanger: Fold hoodies and tees to keep the shoulders from stretching. Keep them away from damp garage or trunk storage. A clean, dry drawer beats a hook in the shop for long-term print life.
