Creating a secure pocket

For Fehr Trade’s latest Surf to Summit top, I added a secure pocket. Here’s how I did it.

My RTW cycling jerseys have close fitting pockets so I adjusted the back pocket and drafted a pocket bag pattern piece.

The new cycling jersey uses left over Stormset print fabric from Funki Fabrics and an invisible zipper from my stash.

I checked the pattern to make sure it fit my phone and also checked the zipper length I need to get the phone into my pocket.

Next I had to figure out the steps to actually sew the pocket together.

Step 1: Sew the zipper to the outer pocket first (right side of the zipper). Use the invisible zipper foot. A 15cm invisible zipper will do.

Step 2: Sew the zipper (left side of the zipper) onto the zipper bag, leaving room for the seam allowance.

Here’s what it should look like.

Step 3: Sew the zipper seams closed at top and bottom. This will take some negotiating because the fabric stretches but the zipper doesn’t.

Step 4: If the zipper needs to be shortened, zigzag the zipper base and cut it to size.

Step 5: Pin the zipper bag to the main pocket piece, ready to sew it closed.

Below is how the back pocket fits on the jersey. I’ve used Fehr Trade’s Surf to Summit sewing instructions to sew the jersey.

I’ll show the finished cycling jersey next post.


  1. Great post. I love the idea of a secured pocket to put my valuables. I've recently made an armband using Fehr Trade's free pattern for the mean time.
    Awesome fabric combo btw


  2. I saw Fehr Trade's link to your work here! This is such a great idea for this top. I'm always awkwardly hanging onto stuff when I'm running–pockets make so much more sense.
