Two Overgrips for Sweaty Hands – Which One Holds Up in a Real Match?

The ball was sitting up on the ad side, a metre inside the baseline. I set up for a crosscourt backhand slice, weight forward, rachead head above the ball, and then — nothing. The grip turned in my hand mid-swing. The ball dribbled into the net tape. My opponent didn't even react; he just walked to the other side.

I've been playing competitive club tennis in West Africa for eight years. Sweaty hands are not a seasonal problem here. They are a constant. I've tried a dozen different overgrips in actual match conditions — not on a practice court with fresh balls and a hopper, but in third-set tiebreaks when the air is thick and my palm is wet before the first changeover.

Here's what I've learned. There are two kinds of overgrip that work for sweaty hands, and they work in opposite ways. One grips you when it's wet. The other soaks up the wet so your hand stays dry. If you pick the wrong camp, no amount of talent will stop your racquet from twisting on a one-handed backhand you've hit ten thousand times.

The Two Camps

Sticky-when-wet grips are made from tacky polyurethane that reacts to moisture. The more you sweat, the tackier the surface becomes. Think of a climbing chalk bag that only activates when your hands are damp.

Dry-absorbent grips are made from cotton or microfiber blends that wick sweat away from your palm. They feel papery or cloth-like to the touch. They don't get tackier; they get drier.

Good. Now you know which category you need. Here are the two overgrips I've tested most thoroughly, head-to-head.

The Contenders

Yonex Super Grap (Sticky-when-wet)

I used Tourna Grip for six years because that's what everyone told me to use for sweat. It was fine. Then I ran out before a tournament and borrowed a Super Grap from a teammate. I hit one serve and stopped. That was five years ago. I haven't used anything else as my primary grip since.

Super Grap feels unremarkable when you unwrap it — smooth, slightly waxy, not especially thick. For the first ten minutes of a match it's nothing special. Then your palm starts to sweat. Around the fifteen-minute mark, the surface changes. The grip becomes soft and adhesive. Not sticky in a tacky-glue way, but in a "your hand is no longer moving independently of the racquet" way. On a humid day, after two hours, it still holds.

How long it lasts: Three to four singles matches, or about six hours of court time. After that the tackiness fades and the grip starts to feel slick where your thumb pads rest.

Honest negative: It does not handle a soaked palm well. If your sweat is heavy enough to bead and run, Super Grap becomes slippery — not because it's bad, but because it's designed to grip moisture, not shed it. Players who drip sweat onto the court between points need a different answer.

Tourna Grip Original (Dry-absorbent)

The blue roll is a classic for a reason. Tourna Grip is thin, cottony, and feels almost like medical tape on your hand. It does not try to grip moisture; it absorbs it. The material is porous. Sweat goes into the grip, not between the grip and your palm.

How it lasts in a match: The first twenty minutes feel great — dry, secure, with that papery tactile feedback that tells you the racquet is exactly where it is. After thirty to forty minutes, the grip compresses and the absorbency drops. By the end of a two-hour match, it's flat and slick. You can still play with it, but your grip pressure will increase unconsciously to compensate.

Honest negative: Durability is poor. One aggressive singles match is about the limit. You can stretch it to two if the conditions are mild, but after that the grip is done. It also has almost no cushioning. Players with arthritis or sensitive hands will feel every ball impact through the handle.

Head-to-Head

You need three honest answers before you choose.

First, what is your hand-sweat volume? Do your palms feel damp, or do you actually drip? If you drip — meaning you wipe your hand on your shorts between every point and the grip is visibly wet — go with Tourna. Super Grap needs some moisture to activate, but it can't handle a flood.

Second, what climate do you play in? Humid heat is the worst environment for both grips. In that case, Super Grap's tacky chemistry works better because it doesn't rely on the air to dry out. Dry heat is kinder to Tourna; the sweat evaporates faster and the grip stays usable longer.

Third, how often do you want to change your grip? If you play once a week and string once a month, Super Grap will outlast your strings. If you play every day and enjoy regripping before a match, Tourna gives you that fresh-paper feel every session.

Who This Is For / Who It Isn't

Super Grap is for the player who stays on court for two hours or more, who wants a grip that settles into its best state as the match goes on, and who is willing to pay a small premium for durability. It is not for the dripper.

Tourna is for the player whose hands are wet before the warm-up ends, who plays best in the first hour, and who doesn't mind changing grips often. It is not for the tight-budget player who wants a grip to last a week of practice.

The Honest Truth

No overgrip turns a wet hand into a dry hand. Tourna soaks up moisture but compresses. Super Grap grips moisture but eventually oversaturates. Both are good. Both have a ceiling.

If you want the grip to do everything, you will keep searching. If you want the grip to do one thing well, pick based on whether your sweat is a slow leak or a fast drip.

The rule of thumb I carry onto the court every night: if your palm is damp before the first changeover, use sticky-wet. If your palm is wet before the first game, use dry-absorbent. The rest is just brand loyalty.
