PB Jam Leggings


This is a digital sewing pattern for close-fitting, workout leggings with contrast swirl design on the upper front thigh leading to the upper back. There’s a hidden pocket inside at the upper centre back, perfect for gels, keys, or your phone, and contrast panels at the back of you knees are perfect for mesh fabrics. An elasticated, high-rise waistband means they won’t shift around as you move, either!

Intermediate sewing skills are required for this pattern - some experience with sewing knits is expected. Note that this pattern requires stretch jersey fabric with good recovery - it is drafted with negative ease!

1cm (3/8in) seam allowances are included except for the waistband edge, where a 4cm (1 1/2in) elastic allowance is included. A 3cm (1 1/4in) hem allowance is also included.

This pattern is designed and tested to print onto both A4 and US Letter paper, and uses 24 pages for the pattern. An A0 compatible "Print at Copy Shop" version is also included.


  • 1m (1 1/4yd) of 150cm (60in) wide main Lycra jersey with at least 50% stretch in both directions and good recovery (wicking lycra is ideal!). Lots of great lycra shops only sell by the whole meter - this is designed so you only need to buy one meter of main fabric!
  • Less than 0.5m (<1/2yd) contrast lycra jersey (if coordinating with the XYT Workout Top, 1m or 1yd of fabric is sufficient for the top and leggings contrasts!)
  • Less than 1m of 2cm (3/4in) woven (aka “braided”) waistband elastic

The v3 update from November 2015 improves the readability of the pattern illustrations and corrects a few instruction typos. The pattern pieces themselves have not been changed.

I am a long-distance runner and also a sewist - I've long been disappointed by the quality and fit of exercise clothing available on the market, so I've been sewing my own for the past few years - even running four full marathons in my own-sewn gear! All my digital sewing patterns have been road-tested by myself and a team of fellow fit sewists.

My patterns are for personal use only. No commercial use of the products made from this pattern or derivations thereof is allowed. So feel free to make them for yourself, friends, family, etc, but you can't sell products made from my patterns.

If you don't sew but love the design, get in touch as I can also make these on demand.
