Ultra Cool Tech Glacier Tape Review: Cooling Bar Tape for Indoor Cycling

Cooling bar tape? Sounds like marketing ice cream. But after a few sweaty Zwift sessions and a scorcher of a trailer tow, we’ve got takes. Is it icy magic or just fancy grip with a chill vibe? Spoiler: our palms are cooler than our parenting strategies.

Indoor cycling is great for structured training. It’s also great for turning your living room, basement or garage into something that feels suspiciously close to a tropical rainforest within about seven minutes.

If you’ve ever done a Zwift session after bedtime, you know the routine: fan on full blast, towel over the bars, another one around your neck, and sweat dripping from places you didn’t even know could sweat.

So when a company introduces something called Glacier Tape — a handlebar tape that promises cooling when you add water — the idea immediately sounds appealing.

Maybe even a little too appealing.

After spending some time riding with it, though, the truth sits somewhere between clever idea and marginal gain.

Let’s take a closer look.

What is Glacier Tape?

Glacier Tape from Ultra Cool Tech is a handlebar tape designed to provide a cooling sensation while riding, especially during indoor training sessions. Once the tape is wet, evaporation and airflow create a cooling effect around your hands and cockpit area.

The manufacturer describes this as an endothermic cooling effect. In simple terms, the material absorbs heat energy from its surroundings while moisture evaporates. That process pulls heat away from the surface of the tape and the rider’s hands, creating a noticeable cooling sensation during use.

Installation works just like regular bar tape. Each package includes two lengths of tape, finishing strips, bar-end plugs and small cheater strips for the lever area.

First impressions

When you first take Glacier Tape out of the box, the texture stands out immediately.

Compared to many modern bar tapes, it feels noticeably rougher and more fabric-like. Not uncomfortable, but clearly different from the smoother surfaces you often see on road bikes today.

Once wrapped around the bars, the tape still feels solid and secure, just with a bit more texture under the hands.

Installation

Wrapping Glacier Tape is straightforward and doesn’t require any special tricks. In fact, the tape stretches nicely and is relatively easy to tension while installing. Because the surface is a bit rougher, it helps to occasionally pull it slightly tighter during the wrap to keep everything neat and evenly aligned.

One important note: it’s best to install Glacier Tape directly on the handlebar without another layer of bar tape underneath. The idea is that moisture can move through the material and evaporate freely. Adding another layer below would trap that moisture and could potentially create an environment where mold develops over time.

For similar reasons, it’s also not recommended to wrap a second thin grip tape over the Glacier Tape. That would reduce airflow and limit the cooling effect the tape is designed to provide.

Cooling in real use

Once the tape is installed, using it is simple: splash some water on the bars, start riding and let airflow do the rest.

The cooling sensation is clearly noticeable when the tape is wet. Your hands feel fresher, and the cockpit area doesn’t warm up quite as quickly during longer indoor sessions. It’s not a dramatic temperature shift, but it adds a pleasant cooling touch that you definitely notice when the room slowly heats up during a workout.

Where Glacier Tape really makes sense is indoors. On the road, natural airflow already cools you quite effectively. But in a warm room during a trainer session — especially the classic late-evening ride after the kids are asleep — every bit of extra cooling helps. With a strong fan blowing toward the front of the bike, the effect becomes even more noticeable because the airflow accelerates evaporation from the wet tape.

Like most evaporative cooling products, the tape gradually dries out during longer rides. Once dry, the cooling effect fades, so it helps to keep a second water bottle nearby to splash some water onto the bars again during longer sessions.

The Cooling Towel

Ultra Cool Tech also offers a Cooling Towel made from a similar material. Used over the shoulders during indoor rides, it works in much the same way: once wet, evaporation creates a cooling sensation.

Because the towel covers a much larger surface area than bar tape, the effect can actually feel quite noticeable across the upper back and shoulders. That larger contact area helps cool a bigger part of the body at once, which can feel surprisingly refreshing during hard trainer sessions.

I also experimented a bit by placing the towel under the jersey across the chest to bring it closer to the blood circulation in that area. At first this did feel slightly cooler, but with the jersey covering it, the effect faded fairly quickly and overall didn’t feel significantly better than simply wearing it over the shoulders.

In practice, the towel behaves much like other evaporative cooling fabrics: it works well right after wetting, then gradually dries out. During longer sessions it helps to re-wet it occasionally, just like the tape.

Pros

– noticeable cooling sensation when the tape is wet
– easy installation similar to regular bar tape
– works particularly well for indoor trainer setups

Cons

– cooling effect is most noticeable in warm indoor environments
– needs occasional re-wetting during longer rides
– texture is rougher than many riders might be used to

Verdict

Glacier Tape is one of those products that sits squarely in the “small gains” category — but in the right scenario, those small gains can still make sense.

If most of your riding happens outdoors in moderate temperatures, you probably won’t notice a huge difference. But if you spend a lot of time indoors on the trainer, especially during sweaty evening sessions squeezed in between bedtime routines and the next early morning alarm, the added comfort can be welcome.

I didn’t measure any performance improvements, and without structured testing it would be hard to claim that anyway. What I did notice is that indoor rides simply felt a bit more comfortable and slightly less overheated.

Glacier Tape won’t magically solve the heat problem in a pain cave. But as part of a good cooling setup — fans, airflow, hydration and maybe a wet towel nearby — it adds one more small trick to make tough indoor sessions a little more bearable.
