Original Red Bicycles end of line - one XS & one 3XL left
Thunderpants organic cotton and elastane fabric is super stretchy, comfy and easy-fit. There’s no nasty, scratchy elastic that digs in making them the ultimate comfy undie.
The undie styles are designed to sit in the natural curves of the body and are cut with plenty of fabric to cover your bum. Because our fabric is a bit thicker than you may be used to and has great retention and recovery, they may feel like they fit a bit tighter.
See the size guide below to help you choose the right size. If you happen to fall between the measurements in the undies, we recommend going up a size rather than down.... Our fabric is stretchy enough that a bigger size will often still fit, but won’t feel as tight. For the other garments, Bike Shorts, Leggings, and Camis, you should be ok in the same size as your Thundies but obviously all bodies are unique and how you want to wear them varies.
The sizes are standard UK sizes.

Hipster vs Original vs Sky Rise?
The three styles are exactly the same around the legs and bottom, the hipster is low rise sits on your low hip, the originals are higher and usually fall just below the belly button, and the sky rise are a high waisted that taper in at the top to sit on your natural waist.

The original comfy undies that don't go up your bum. In sizes small through to 3XL, check our size guide against your measurements. This very comfortable full brief sits in the natural crease at the top of the leg and just under the navel. Thunderpants are cut with enough fabric to cover your rear end and the comfy bands hold them in place so even the most active folk will no longer need to readjust their underwear.
-
The Thunderpants fabric is 90% organically grown cotton and 10% elastane to give it that super comfy, soft stretchy feel. The waist and leg bands are constructed in the same, lovely fabric eliminating the need for the addition of nasty, grippy elastic and adding to the enjoyment of your Thunderpants experience. All the garments are made locally and lovingly in the UK.
-
To preserve the print and life of the fabric we suggest you do not soak or bleach your Thunderpants items. Use a gentle detergent in a cold machine wash and dry your Thunderpants on the line, not in the drier.
Your Thunderpants are not only super comfy but they are designed to withstand some pretty staunch stuff, so get into them and get on out there!
