Interlock explained in simple words

Short answer: What is interlock? It is a knitted fabric construction where two layers of loops are locked together, so the fabric is smooth on both sides, stable and a little thicker than single jersey. Here is a simple explanation of how it works and what it means for the garment.

What interlock is in simple words

Interlock is a way of knitting jersey. Instead of one layer of loops, two layers are knitted and interlaced, so the fabric has the same smooth surface on both sides. That makes the fabric firmer and more stable in shape than ordinary jersey, which is why it is used in many basic garments.

How interlock differs from single jersey

Single jersey is thin and stretchy, and the edges often curl. Interlock lies flat, the edges rarely curl, and the fabric feels thicker and more compact. How much you notice depends on yarn and weight. The difference is clearest when you hold the two fabrics side by side.

Why interlock is used in clothing

Because interlock is stable and smooth, it can be used for T-shirts and other garments next to the body. Look at the range for men to see which garments exist. Read the product description if you want to know which knit a particular garment has.

How interlock feels

Interlock is often felt as smooth and slightly dense, and it has an even surface on both sides. That means the garment feels nice on the inside too. The feel depends on fibre and yarn as much as on the knit. Try a garment and judge for yourself how it feels after a full day.

Interlock and fit

A dense fabric can sit a little more firmly than a thin fabric. That means the size can feel different, even if the measurements are the same. Measure yourself, compare with the size guide and think about how closely you want the garment to fit. Read the description for tips on fit.

Washing and care of interlock

Interlock is often durable, but always follow the care label. A gentle cycle, a sensible amount of detergent and air drying help the fabric keep its shape. High heat can pull the fabric together and affect the surface. Turn the garment inside out so the surface is protected from rubbing.

Interlock in everyday life

The dense fabric can suit you well when you want a garment that keeps its shape over time. A T-shirt with a stable fabric can be easier to wear under other clothes. Look at bamboo T-shirts for men and bamboo boxer briefs to see how the material is used.

How to read what a garment is made of

The description often shows fibre, weight and knit. Words such as interlock, jersey and rib say something about how the fabric is knitted. Use them to compare garments with each other. If something is unclear you can always ask, and that is better than guessing what a word means.

Frequently asked questions

What is interlock

Interlock is a knitted fabric construction where two layers of loops are locked together. The result is a fabric that is smooth on both sides, stable and a little thicker than single jersey.

Is interlock thicker than jersey

Often yes, because two layers of loops are used. How thick it feels also depends on the yarn and the weight of the fabric.

How do I wash interlock

Follow the care label, choose a gentle cycle and avoid high heat when drying. Air dry if you can so the fabric keeps its shape.
