Frequently Asked Questions
The Helios is lighter (3.2 oz vs 5+ oz) and more packable than most Tilley models, with comparable UPF protection. Tilley hats often have more structure and may be better for very windy conditions, while the Helios excels in breathability and packability.
Absolutely. The Helios is ideal for hiking with its lightweight design, excellent ventilation, and secure fit. The 3-inch brim provides superior sun protection without being so large as to catch branches on narrow trails.
The Helios can be completely crushed and packed into a backpack pocket or luggage without damage. It springs back to shape remarkably well. For travel, you can roll it and secure with the chin cord to minimize space.
