Review REI Kids Black Thermal Base Layer Bottom Long Johns Polyester Spandex

Introducing the REI Co-op Rainier Kids' 10-12 Thermal Base Bottoms, a must-have essential for keeping young adventurers warm and comfortable during chilly outdoor activities. These base layers are designed specifically for kids sized 10-12, ensuring a perfect fit for growing bodies.

Made from a soft and flexible 4-way stretch spandex fabric, these thermal base bottoms provide both insulation and freedom of movement.

The bottoms also have a handy elasticized cuff at the ankle to help keep them in place under boots or pants.

This product is not only functional but also environmentally friendly. The fabric is made from 100% recycled polyester, reducing the impact on the environment. The Rainier Kids' 10-12 Thermal Base Bottoms from REI Co-op are the perfect addition to any child's outdoor wardrobe, providing warmth, comfort, and durability for all their adventures.
