The fabric that says, "I’m ready for anything". 

DayFlex is a bonded poly-nylon that's super smooth, water-repellent, and perfect for both bag exteriors and linings. We named it DayFlex for its versatility – from lunch bags to makeup pouches, travel organizers, fanny packs, and more.

The magic is in the bonded lining – a thin, smooth layer that’s permanently fused to the back of the fabric. It:

  • Adds stability and structure so your fabric isn’t floppy, even without interfacing
  • Makes cutting and sewing easier because the fabric doesn’t fray or stretch while you work

Which means, no interfacing is needed for most projects. But if you’re looking for a little extra structure, sew-in interfacing is your BFF.

✨ Why You’ll Love It

  • Sleek, smooth surface that wipes clean like a dream
  • Water-resistant finish to keep spills and messes in check (because life happens)
  • 280 gsm – the perfect balance of structure without the bulk
  • No interfacing required (but it works beautifully with sew-in interfacing for that extra body)
  • Easy to sew on your domestic machine – no stress, no fuss
Content 100% polyester. Non-stretch.
Cut Size Available in pre-cut 1-yard pieces (36” x 56” WOF). Not cut continuously if you order multiples.
Weight 280 gsm

Miles ★★★★★

I was pleasantly surprised by how smoothly the zipper glides along this fabric—no snags at all. It shed a quick coffee spill without any stain, which is exactly what I needed for daily use. The smooth texture also makes it effortless to wipe clean after outdoor trips.

Jacob ★★★★★

Rain rolled through my whole commute and the bag I made from this held up without a single damp spot, which is exactly why I picked the water-repellent finish. The bonded poly-nylon surface is so smooth it glides over my shoulder, and it's sturdy enough for both the outside and the lining without ad

Stella ★★★★★

I've been using this fabric for bag linings and the bonded poly-nylon feels way smoother than any other material I've tried. It's water-repellent too, which saved my stuff during a light drizzle.
