"Lightness" is one of the most crucial features for mountaineering apparel and gear.

The lighter the item, the more you can reduce your base weight (the total weight of your backpack at the start of your hike, excluding consumables), and it also decreases the strain on your body. That’s why professional mountaineers are always searching for wearables and gear that are even a gram lighter.

Shell jackets, which are typically on the heavier side, have seen countless brands experiment and strive for lighter designs.

Amidst the competition, the "mont-bell" "Ultra Light Shell Parka"—which debuted in 2020—truly stands out.

It weighs just 136g on average. For context, that’s about the same as a single D-cell battery, and even lighter than your typical banana. Yet, it boasts stretchability for free movement and high-performing features like moisture absorption and quick-drying abilities. Best of all, it comes at a remarkable price: just 9,900 yen (tax included).

Let’s uncover the secrets behind Montbell’s lightest ever soft shell with PR representative Tetsushi Hosako.
