Our latest Thermal Theory design has arrived in store - our customer favourite Sherpa Lined Thermal Leggings, now with two phone pockets.

Offering the same warmth, comfort and flexibility as our regular leggings but with the added advantage of two full sized upper leg pockets which can fit the largest phones on the market (iPhone 14, Samsung Galaxy S23 Ultra etc). Perfect for when you're on the go and need your hands free.

These leggings are made with thermal performance fabric that stretches for a secure fit, while their high waisted design allows for a full range of motion without riding down. Designed for cold temperatures, with a super-soft short pile sherpa lining is thick without being bulky so you'll stay warm in style.

Note for sizing - These leggings can fit a range of sizes which are indicated on the sizing tags. They are not a compression legging. They are soft and comfortable, with a thick but flexible fabric. 

Available in Classic Charcoal Black in sizes XSmall to 2XL (Aust Women's 6-20).

What are Thermal Theory clothes made from?

Our Premium Sherpa Collection is made from a dual-layer thermal tech fleece.

The outer layer consists of :

  • 70% Cotton, 25% Polyester, 5% Spandex
  • Cotton provides breathability and softness, the polyester aids against pilling and colour fading, and the Spandex gives the material some elasticity which keeps its shape.

The inner layer/lining consists of :

  • Premium brushed sherpa fleece (Polyester)
  • This product will not pill or clump together like cheaper brands and will retain it's soft fluffy texture, even after multiple washes.

Other features:

  • 550gsm fabric. This is premium heavyweight!! GSM stands for grams per square metre, which refers to the weight of a fabric. In general, the higher a fabric's GSM, the thicker and more hard-wearing it's likely to be. eg. a T-shirt is usually less than 150gsm.
  • Windproof weave. Due to the density of the fabric it provides a unique windproof layer which adds to the thermal properties and keeps you warm.
  • 12+ TOG rating . This is made for low temperatures. TOG stands for 'Thermal Overall Grade". This is the measurement of the fabrics ability to retain and trap heat. The higher the TOG value the warmer your clothing will be.

How do I care for my purchase(s) when it needs to be washed?

Please follow our care instructions to ensure your clothing stays in it's best possible condition. Failure to do so may cause damage to the material.

  1. Program washing machine to a cold water wash. 
  2. Use a sensitive/gentle wash cycle.
  3. Use a gentle laundry detergent. Do not bleach.
  4. Do not use fabric softener.
  5. Dry on a flat surface and turn inside out to check inner layer has dried too.
  6. Can be finished in the dryer on low temp.

*If desired the material can also easily be washed by hand. Follow the same instructions #3 to #6.

I love them

Warm as toast

Thank you Thermal Theory for wonderfully warm sherpa lined leggings with pockets. So toasty warm and comfortable to wear on cold mornings. The pockets are just right for a mobile, car keys and credit card.
Thermal Theory provide excellent customer service. They helped clarify my query and were prompt in their response.

Almost perfect pants!

Love these so much. My legs are always really cold and these have fixed it. I'm so cosy now. I bought the ones with pockets as well as the ones without. The ones with pockets fall down a bit, otherwise they would be absolutely perfect. I wear them around the house, walking down the street, and even to a fancy restaurant last night!! Life changing. And I shouldn't have to say it, but as a size 18 - I'm so glad these come in my size. Thank you!!
