Neoflex V2 vs Hexatex: Fabric for Stretchy Bag Projects

Two fabrics, two different kinds of stretch

If you're planning a bag that needs some give—whether for a snug fit or a soft, structured shape—you might be weighing Neoflex V2 against Hexatex. But these fabrics serve different purposes, and only one is designed to stretch. Neoflex V2 is a 2.0mm thick neoprene with a flexible core, while Hexatex is a water-resistant ripstop polyester that offers durability without stretch. Understanding their differences will help you choose the right material for your project.

What each fabric actually is

• Kitty Krew Neoflex V2 (2.0mm Thick) Half Yard: Kitty Krew Neoflex V2 is a 2.0mm thick neoprene with a smooth, soft-touch exterior and a solid interior. It is naturally waterproof and insulative, and holds shape without added foam or interfacing. This makes it a strong candidate for projects that need both structure and a bit of flexibility, like insulated lunch bags or drink cozies.

  

• Inkscape Hexatex (YD): Inkscape Hexatex is a custom-printed water-resistant ripstop 420D fabric made from 100% polyester, with a ripstop weave for tear resistance and UV resistance. Hexatex is built for durability and weather resistance, not stretch, so it suits bags that need to hold their shape without giving.

  

Stretch and structure: how they behave in a bag

• Flexibility: Neoflex V2 has a flexible neoprene core that allows some stretch, making it ideal for form-fitting or insulated items. Hexatex is a woven ripstop with no inherent stretch, so it provides firm structure.
• Shape retention: Neoflex V2 holds its shape beautifully without extra interfacing, thanks to its thickness. Hexatex also maintains shape but may require interfacing for structured bags, though it is not recommended for use with fusible interfacing.
• Best uses: Neoflex V2 shines in insulated lunch bags, drink cozies, travel organizers, and structured accessories. Hexatex is great for bags, tents, banners, and other projects that need water resistance and tear strength.

Sewing considerations: machine compatibility and needles

Neoflex V2 is not domestic-machine friendly due to its 2.0mm thickness and resistance. It sews best on a walking-foot or industrial straight-stitch machine. Use a Microtex 90/14 needle for clean penetration, and choose bonded polyester or heavy-duty thread. Construction seam allowance is 3/8" and topstitching is 1/4", with stitch lengths of 3.0–3.5 mm for construction and 4.0–5.5 mm for topstitching.

Hexatex, on the other hand, is domestic-friendly and can be sewn on a standard machine. It is a ripstop polyester, so a standard needle and all-purpose thread work well. However, it is not recommended for use with fusible interfacing, so plan your structure accordingly.

Key specifications at a glance

• Kitty Krew Neoflex V2 (2.0mm Thick) Half Yard: Sold in half-yard rolls: 18"x52". May have a light manufacturing scent that airs out easily. Compression creases may occur and can be minimized with a quick heat-press (test first). The half-yard size is generous for small projects, and the care notes help you prepare the fabric before sewing.
• Inkscape Hexatex (YD): Sold by the yard, precut. Width is 36"x58". Water-resistant and UV resistant. Not recommended for use with fusible interfacing. The yardage and width give you ample material for larger bags, and the water resistance adds outdoor durability.

Making the choice for your stretchy bag project

If your project requires stretch—like a wetsuit-style bag, a cozy, or a form-fitting organizer—Neoflex V2 is the clear choice. Its neoprene core provides flexibility and insulation, and it holds shape without extra interfacing. Just be prepared to use a walking-foot or industrial machine and a Microtex needle.

If you need a durable, water-resistant fabric for a structured bag that doesn't need to stretch, Hexatex is the better option. It's domestic-friendly, tear-resistant, and UV resistant, making it ideal for everyday bags, outdoor gear, and accessories. Keep in mind that it doesn't stretch, so it won't suit projects that rely on give.
