Neptune Thermoregulation System (Unisex)

The shirt fits as expected. The body warmers keep me warm. But, the water still got into the pouches a little and the warmers wanted to come out of the shirt. Their should be an additional flap to help hold the warmers in. Absolutely love the shirt and recommend it.

This shirt is a game changer for obstacle course racing, or cold weather running! I wore it for the first time in 30 degree weather with wind chills in the low 20's. within fifteen minutes I had to roll up my outer sleeves and take off my gloves, I was that warm. The material felt comfortable and the extra long waist kept the shirt from riding up. I would recommend this shirt to everyone, it is worth every penny.

The Neptune system is a must have for anyone that spends time outdoors during the cold (hunting, kids sports games, adventure racing, cold weather training etc). I've used my Neptune system several times during the cold and have no issues. Normally the chemical heaters are deactivated if water is encountered, however this system has solved for that and allowed me to keep moving with six warm heaters while constantly being in and out of water in a 24 hour Endurance race. The shirt itself is very comfortable and doesn't ride up like many other compression shirts.

Excellent product. Helped me at Worlds Tougest using with water throughout the night and the pouches stayed dry and warm. Looking forward to expanding my use for hunting this year in the winter. It fit as expected, was very comfortable and easy to care for. Their customer support is great 👍

I have used this shirt for the January 1 - 5k and Polar Plunge. Amazed how long the packs last. Not bulky as you might think they would be. Definitely I smart investment if you spend time in the colder weather elements.
