We recommend washing the t-shirt at a maximum temperature of 30°C (86°F). Where possible, allow the shirt to air dry. If you must use a machine dryer, then we suggest using a cold setting.

Avoid ironing the printed logo, as this may damage the print.

We recommend washing the socks in water no higher than 40°C (104°F), as this will ensure longevity of the material and prevent any potential shrinkage from high heat.

Allow the socks to air dry after washing. We strongly recommend against putting the socks through a machine dryer as the heat can affect the material of the socks.

Aspire Wrist Wraps

JCMB-team — Fri, 30 May 2025 10:06:46 +0000

Wrist wraps relied on by strength athletes around the world, available in two versions and three lengths, to accommodate for every preference.

Flexible – Designed to support the wrist while allowing the wrist to flex, designed for superior moulding to the wrist, and upgraded comfort during supported wrist flexion.

Stiff – Designed to cast and immobilise the wrist, now with a softer finish, to resist wrist flexion while minimising discomfort.

Aspire is a limited edition collection, offering the same performance and manufactured to the same high standards as our classic product line.

Sold as a pair.
IPF approved with the maximum width (8cm) and available up to the maximum length (1m).
Proprietary wide elastics developed and manufactured specifically for wrist support.
Powered by VELCRO® Brand hook and loop
Left and right designs for equal wrapping of each wrist.
Made in Sheffield, Great Britain.

Size
Small (40cm/15.7in)	Small wrists
Medium (60cm/23.6in)	Standard size for medium-large wrists
Large (100cm/39.4in)	Maximum competitive use

Support
Flexible	To allow some wrist flexion
Stiff	To fully immobilise the wrist

Most athletes prefer a medium-length, flexible wrist wrap, suitable for a variety of exercises.

If you have a very small wrist, we would recommend choosing the small length.

The large flexible wrap is ideal for those wanting a versatile wrap which, depending on how many times it is wrapped, can be altered to be more or less supportive.

Athletes looking for maximal support can try the stiff version of our wrist wraps, which we would typically recommend as a second pair of wrist wraps to complement our flexible wraps.

We recommend hand washing the wrist wraps with warm water and a mild detergent, and then allow the wraps to air dry. Do not machine wash or dry, as this can damage the material of the wrist wraps.

Measure the circumference of your knee joint with your leg out straight, keeping your muscles relaxed. Measure around the centre of your kneecap (at the patella), and around the thickest part of your calf. If your calf is more than 4cm (1.6in) larger than your knee, then you may wish to size up to ensure a good fit.

If you are new to wearing knee sleeves we recommend going with the recommended fit instead of sizing down, especially if you fall on size medium or smaller.

We recommend hand washing your knee sleeves with water or a mild detergent (or a specialist neoprene/wetsuit detergent), then allow the sleeves to air dry standing up.

The spin cycle of a washing machine can damage the sleeve, as the knee sleeves become quite bulky when wet and can potentially get caught up or damaged by wringing. High heat from a washing machine or a dryer will degrade the rubber in the sleeves (potentially causing shrinkage or brittleness).
