In-Game Recovery for Athletes

The Narwhals™ are a palm cooling device for accelerating recovery during practices and competitions, and avoiding heat stress.

Accelerate heart rate recovery during timeouts 

Cool down quickly during breaks without removing gear

Extend work capacity during high intensity work

Reduce perspiration and loss of electrolytes 

If you’re not thinking about thermoregulation, you’re leaving points on the table.

The first game I used it, going into the second and third period, I noticed a difference. I just felt a little clearer mentally, then physically felt a little bit less heavy or fatigued as the game went on.
James van Riemsdyk, NHL Left Winger
We’ve been using the Narwhals from Apex Cool Labs for over a couple of months now. It’s made a clear difference in recovery during training sessions. Athletes recover faster and can sustain higher intensities for longer. The palm cooling technology is especially useful for us here in Arizona, where we’re often training in 100+ degree heat. The Narwhals are now part of our daily setup, and I recommend them whole-heartedly.
Stuart McMillan, ALTIS | CEO / Sprint Coach
The Narwhals have been crucial in helping me maintain the focus and intensity required to excel on the defensive end, especially in those high-pressure moments late in the game.
Kindyll Wetta, Point Guard, CU Women’s Basketball
Our athletes love the Narwhals as they allow them to recover faster in competition and prepare for our long season. We have used them every game for the last two seasons and will continue to do so. The company and product are at the top of the field.
Paul Valukas, D1 Strength & Conditioning Coach
The Narwhals have made a significant impact on our thermoregulation model for our parathletes. We now have a proactive method for managing heat before it becomes a problem and extending our athletes’ ability to perform at higher intensities longer.
Alex Curry, Director of Sports Medicine, Adapted Athletics, University of Alabama
To me, they are a no-brainer as a recovery tool for any team sport that is intermittent in nature, and they can also significantly enhance performance in the gym. Apex Cool Labs has developed a superb product and provides excellent customer service.
Joel Jackson, NHL Strength & Conditioning Coach
I’ve been using my Narwhals consistently during training and recovery for over a year now and have loved how fresh and ready-to-go they help me feel! I have especially loved adding them to my wind-down routine after late practices and games to help me get more quality sleep and recovery.

As ambient and core body temperatures increase, performance declines. By cooling between bouts of effort you can sustain a higher level of play longer.

Avoid heat stress

Recover heart rate faster

Increase work volume

A more powerful way to cool down is within reach

Our palms are natural radiators for the body. They contain special vasculature for efficient offloading of heat.

By holding something cool (not cold), with good thermal conductivity, and a mechanism for avoiding thermal barriers, you quickly remove excess body heat, accelerating recovery and improving performance.
