Designed as the ideal companion on excursions where a little insulation is needed, the No. 503 was crafted to sit next to your skin providing lightweight insulation with moisture wicking prowess. The Polartec® Power Dry® grid pattern textile features a patented bi-component knit construction that creates two different surfaces: one that is optimized to move moisture away from the skin, the other to dry quickly. The Henley style pull-over and Midtop™ collar allow for the greatest flexibility in heat retention, combined with the soft elastic ribbing cuffs for easy layering.

The mountains have a unique way of testing your resilience. The cliffs and cold push you to your physical and mental limits. Your emotions will play endless games with your pursuit of the summit. Few will ever be able to comprehend what these moments are like; what that climb was like. Few will understand the feeling of gravity and fear pulling you down, while your passion and determination push you higher. It is for these moments, these experiences, that our mountain wear is designed.
Driven by a desire to make products with fortitude and inspired by our passion for the experiences only found in the mountains, we are determined to make mountain wear reminiscent of a time when climbing was in its purest form and excellence was found in all aspects of a product. Performance and quality were as important as style and design, with none taking second place.
