Extreme Heat and Performance: SIXS Chooses Dryarn® for the New Ultra-Light LIGHT BT V2 SS26 Line

How can you tackle the hottest days on the track, on a bike, or during the most grueling trails without sweat becoming an obstacle? For the Spring/Summer 2026 season, SIXS answers this need by presenting the revolutionary LIGHT BT V2 line: the evolution of the lightest and most breathable base layer ever developed by the Italian brand.

Designed to dissipate body heat rather than retain it, the new collection is a full 40% lighter than the traditional 4-Season line. The secret to this extraordinary performance lies in the use of Dryarn® microfiber, a high-performance polypropylene yarn that never absorbs moisture. Instead, it instantly transfers it to the outside, promoting rapid dispersion.

Compared to the previous generation, the V2 version takes a further leap in quality by introducing even more durable solutions in high-stress areas, an improved anatomical fit, and “multi-zone” engineering (solid knit for strength, mesh areas for extreme sweat ventilation, and ribbing for elasticity).

Three Key Pieces of the New SS26 Collection:

BT STXL R V2: The Ultimate Undersuit for Motorcyclists

Designed to excel on the track under leather suits, but also perfect for summer touring, the BT STXL R V2 full-body undersuit uses the full thermoregulating power of Dryarn® to become the number one ally against scorching temperatures.

This garment eliminates friction under protective gear and, by wicking sweat away, prevents annoying skin irritation.

The V2 evolution introduces a redesigned elastic waistband to perfectly follow the riding posture, ensuring lumbar stability without pressure on the abdomen.

BT CC2L: Under-Shorts with Advanced Padding for Cycling

Developed to work under technical suits and trousers on intense hot days, the BT CC2L shorts combine the extraordinary lightness of Dryarn® with targeted protection for those who spend many hours in the saddle.

Its real strength is the integrated technical pad: it offers ergonomic shaping at the groin, thick foams to absorb vibrations, and a removable rear part for modular protection management.

The multi-zone construction and a new reinforced material solution guarantee maximum resistance to rubbing, stability under protections, and skin that stays dry at all times.

BT TS1L V2: The Short-Sleeved Shirt for Multisport

Whether for motorcycling, cycling, running, or high-intensity outdoor activities, the BT TS1L V2 short-sleeved shirt is the ideal Dryarn® “second skin” for sweltering days.

Thanks to a meticulous anatomical study, the V2 version features a redesigned sleeve to fit perfectly in the underarm area (improving sweat management and eliminating folds) and a low-profile collar to minimize bulk under jackets or protectors.

Technical Advantages of the SIXS LIGHT BT V2 Line

All garments in the new summer collection share excellent technical features, strictly 100% Made in Italy:
