Natural Performance Wear

OUR STORY

We're Unwaver
(the new identity of Tigil)

Unwaver is a sports and lifestyle brand born from a simple belief: nature created over time materials that offer the best performance. That is why we design technical clothing using natural materials, with a strong focus on wool.

Hiker in rugged mountain terrain

Our journey began with a question: why has the outdoor industry almost abandoned the materials that kept explorers warm for thousands of years? While synthetic insulation dominates the market, we looked back to move forward. Wool has been trusted by mountaineers, shepherds, and adventurers across generations. It breathes, regulates temperature, resists odor, and performs when wet, qualities no synthetic can truly match.

Our name says it all. To be unwavering is to stay true to your path, to trust in time-tested materials, and to refuse compromise. We are not chasing trends. We are returning to what works, refined for modern performance.

Unwaver launches with two essential pieces: a wool-quilted ultralight vest and jacket. These garments are designed for the trail, the summit, and the city street. Very soon, we will have improved versions of our 100% merino wool base-layers and mid-layers (currently available under Tigil brand) as well as all the socks and accessories.

PHILOSOPHY

Nature Over Synthetic

From synthetic compromise to natural performance

Synthetic fibers close-up

We choose
wool.

Synthetic insulation dominates outdoor apparel because it's lightweight and cheap. But it degrades with use, traps moisture, and loses warmth over time. Down offers great thermal efficiency yet fails in wet, dynamic conditions.

We choose wool. It breathes, wicks moisture, resists odor, and regulates temperature naturally. Our solution brings wool insulation and garments to the outerwear market — performance that lasts without compromise.

Insulations
Comparison

When comparing insulation materials, wool consistently outperforms synthetic alternatives in breathability, durability, odor resistance, and environmental impact.

While down excels in warmth-to-weight ratio, it fails in wet conditions—exactly when you need insulation most. Wool maintains its thermal properties even when damp.

Our story

From Tigil to Unwaver

Our manufacturing home is Ecovolve in Arandjelovac. From it came Tigil—merino performance and casual wear, from socks to base and mid layers, with the line Feel better, go further. Biodom is our official shop and showroom; Revolana is our bedding line.

Unwaver is the rebranding of Tigil: a new name and visual system for the same workshop and products, with a sharper focus on technical outerwear and a global audience—the line you know from Tigil, expressed as Unwaver.

Unwaver was created first by Milena and Lionel Mestre, who founded Ecovolve and launched Tigil. Yvann then led the next stage of the identity work. Yovan joined afterward to help build the brand forward.
