Manufacturer description
The Corsair MM350 PRO Extended XL gives you 36.6 by 15.7 inches of continuous cloth surface, which is enough room to seat a full-size keyboard and still leave a wide arc for low-DPI mouse sweeps. That 930mm x 400mm footprint is the whole point of this pad: your keyboard stops drifting into the mousing zone, and flick shots run out of desk before they run out of pad. Corsair builds the surface from a micro-weave fabric, a dense weave meant to keep glide fast and consistent rather than draggy, and finishes it with a spill-proof, stain-resistant coating so liquids bead up and wipe away instead…
SpecPicks Verdict
SpecPicks scored Corsair MM350 PRO Extended XL Spill-Proof Cloth Gaming Mouse Pad using a rating × review-volume × price-fit model applied to published specs and reviews across the gaming peripherals category. Corsair's gaming peripherals lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here. Judge it on the specification table and the price rather than on sentiment: check the figures that decide your use case, then put it side-by-side with two or three close alternatives in the Compare tool before clicking through.
Common buyer scenarios for gaming peripherals of this kind: matching it to an existing build, replacing a failing part, or upgrading from a previous-generation equivalent. Check the spec table below against your current setup — particularly socket / form-factor / power-rating fields — and confirm compatibility on the retailer's listing before purchase.

Frequently Asked Questions
What are the exact dimensions of the Corsair MM350 PRO Extended XL?
The surface measures 930mm x 400mm, or 36.6 inches wide by 15.7 inches deep, with a 4mm-thick rubber base. Measure your desk first: you need at least 37 inches of clear width for it to lie flat.
Will it fit a full-size keyboard and a mouse at the same time?
Yes. At 36.6 inches wide, the pad is sized to hold a keyboard, a gaming mouse, and more, per Corsair's description. A full-size 104-key board takes roughly 17-18 inches, leaving about 19 inches for mousing.
Is the spill-proof coating actually waterproof?
Corsair describes it as a spill-proof, stain-resistant coating that liquids slide off of, so the pad wipes clean after an accident. Treat it as spill resistance for quick cleanup, not as a claim that it can be submerged.
Is the surface fast or slow for low-DPI aiming?
It uses a micro-weave fabric, which Corsair specifies as a dense surface for a faster, smoother glide. That puts it on the fast end of cloth, closer to a speed pad than a control pad.
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 most common failure mode on unstitched cloth pads. Check the product listing for current warranty terms.
