Save your knees. A 7.5-inch square you toss on the ground and kneel on — for the shot under a branch, the putt from a knee, the lie on rock or wet gravel or thorns. Sold as a two-pack for about $15, twelve colours.
The important spec is the thinnest one: it compresses to under one centimetre, which is exactly what PDGA rule 813.02 requires of a towel or pad placed under a supporting point. That number isn’t a feature, it’s the whole design constraint. (Towch’s own site cites the wrong rule number for this — 813.02 is the current one.)
Why it matters beyond comfort: knees are the fourth most commonly reported injury site in disc golf, and meniscal surgery is one of the two most common procedures among injured players. That’s not a promise a foam square prevents anything — nobody’s studied that. It’s a reason to stop treating your knees as disposable.
Fair warning: it’s a loose pad, so you have to remember to pick it up. And at under a centimetre it’s dirt-and-damp protection, not impact padding.
