Whether you are looking for a thermal top with the right stretch, breathability, or comfort, K2 Base Camp has something for your next adventure.
How to select the best thermal top for your activity
All the thermal tops in our collection are designed with versatility and purpose in mind. Most thermal tops are made of 100% merino knit wool for their superior warmth, moisture-wicking, temperature regulation, and softness.
Icebreaker is especially well-known for its merino wool and synthetic fibre blend thermal tops, delivering further performance features. A light-medium thermal top with a 200gsm density is the ideal weight for hiking, climbing, and camping. Tops with a density greater than 200gsm will provide you with additional thermal protection to suit freezing conditions.
