Pros & Cons

- ✓ Spill-proof coating sheds liquid instead of soaking into the cloth

- ✗ Extended pads are awkward to wash and slow to fully dry
Manufacturer description
The Corsair MM300 PRO Extended gives you a 930mm x 300mm (36.6" x 11.8") desk surface, which means your keyboard and your mouse share one continuous cloth pad instead of fighting over two. That matters most at low mouse DPI, where wide sweeps run off a standard pad mid-flick. Corsair's micro-weave cloth is woven dense rather than plush-soft, so the mouse feet glide quickly and predictably across the whole span, and the 3mm plush rubber base adds enough padding to keep your wrist comfortable through a long session without turning spongy under the keyboard. The surface carries a spill-proof…

Frequently Asked Questions
Will the Corsair MM300 PRO Extended fit my desk?
It measures 930mm x 300mm (36.6" x 11.8"), so measure your usable depth and width first. Desks under 37 inches wide will have the pad running edge to edge or overhanging.
Is this mouse pad actually waterproof?
It has a spill-proof, stain-resistant coating, so liquids slide off the surface rather than absorbing, and you wipe it clean. Corsair describes it as spill-proof, not submersible.
How thick is it, and is it comfortable for long sessions?
The base is 3mm-thick plush rubber, which Corsair specifies for hours-long play. It is a mid-thickness pad: cushioned under the wrist but not a padded wrist rest.
Will the edges fray or peel over time?
The perimeter has 360 degrees of stitched anti-fray edging specifically to guard against surface peeling, which is the usual failure point on unstitched cloth pads.
Is this fast or slow for gaming?
The micro-weave fabric is woven dense for a faster, smoother glide than a standard plush cloth pad, though any cloth surface is slower than a hard pad. Good for low-DPI wide sweeps.
