Our Membranes and Linings

The performance SEGURA designed and developed by our teams

When choosing a blouson or a jacket motorcycle, it is essential to understand the respective roles of two key technical components: the lining and the membrane. Although often confused, these two layers have very different functions but work together to ensure your comfort in all circumstances.

Our membranes bwtech

The membrane is a waterproof and breathable layer inserted into the garment, often between the outer layer and the lining. Its mission: to prevent water and wind from entering while allowing water vapor (sweat) to escape. It allows you to stay dry and avoid internal condensation. At Segura, membranes are named BWTECH, also available in 4 performance levels (Classic, Super, Mega, Extreme). They differ according to their waterproof index (8000 to 10,000 mm) and their breathability level (3000 to 4900 g/m²/24h).

BWTECH Classic

The basic waterproof protection for daily use.

BWTECH Classic is designed to effectively protect against moderate showers while maintaining comfortable wear. It allows sweat to escape, thus avoiding the feeling of dampness. Ideal for daily commutes, in the city or over short distances.

BWTECH Super

The right balance between weather protection and comfort.

BWTECH Super offers superior breathability to the Classic version, for better management of body moisture during slightly longer or dynamic rides. The waterproofing remains reliable in all circumstances. Suitable for regular use, in all weather, for active motorcyclists.

BWTECH Mega

For those who ride long distances, regardless of the conditions.

BWTECH Mega is designed for those who ride often and long distances. Its high breathability allows rapid evacuation of heat and sweat, even during exertion or prolonged wear. Perfect for long outings, sporty rides, or road trips.

our shelltech linings

The lining is an insulating inner layer, integrated into the garment to retain body heat. It aims to protect you from the cold, ensure good thermal insulation, without suffocating. At Segura, linings are categorized under the Shelltech technology, available in 4 performance levels (Classic, Super, Mega, Extreme), based on their ability to retain heat.

Shelltech Classic

Lightweight and versatile insulation.

The Shelltech Classic is a quilted liner with vertical stitching. It is thin and lightweight, offering an initial layer of insulation suitable for mild conditions. Designed for intermediate seasons or mild climates, this liner provides basic thermal comfort without weighing down the jacket. It is suitable for daily city commutes or short outings when the cold is not intense.

Shelltech Super

Intermediate insulation.

The Shelltech Super is a quilted liner enriched with aluminum inserts and welded vertical quilting. It has a denser construction than the Classic, providing better heat retention. It is aimed at motorcyclists seeking more consistent insulation for comfortable winter riding, without reaching extreme conditions. It remains flexible, comfortable, and suitable for regular use.

Shelltech Mega

Enhanced insulation with technical inserts.

The Shelltech Mega is a quilted liner enriched with micro-fleece and aluminum inserts (horizontal quilted stitching). This model is designed to withstand lower temperatures. The aluminum inserts reflect body heat inward, making it particularly effective in winter or during extended rides in extreme cold.
