Assos GT Ultraz Winter Booties – Overshoes

The GT Ultraz Winter Booties are constructed with ASSOS’ dual-layer twinDeck textile construction for maximum insulation and weather protection in the harshest winter conditions.

Insulating winter overshoes for the coldest days: the GT Ultraz Winter Booties by ASSOS

ASSOS wanted to create the ultimate stormproof head-to-toe outfit that could keep serious riders on the road regardless of the weather. Building on their standard GT Winter ASSOSOIRES, the Ultraz Winter Booties offer additional textile layers to boost insulation and protection in these most extreme environments.

Wear the booties over your shoes in the most challenging winter conditions, paired with the Ultraz Winter Socks, Speerhaube, and GT Ultraz Winter Bib Tights for maximum lower-body protection.

ThermoShell is the primary textile used, applied in two overlapping layers. This 3-layer softshell features a PU-bonded membrane plus a perforated circular knit face – increasing breathability without sacrificing thermal protection. There’s also a DWR treatment on the outer layer for one extra level of protection.

In addition to ASSOS’ dual-layer twinDeck construction, the booties feature a reverse camlock zipper, while the zeroCuff creates the smoothest transition possible between your legs and the fabric, furthering the aerodynamic profile.

Technology

ALS (ASSOS Layering System)
Less is more. The entire ASSOS collection is conceptualized around this technology. ASSOS apparel is engineered with minimum volume, taking advantage of the body’s natural heating/cooling capacities by insulating intelligently through pro-active layering. Both fabrics and garments have chain functions and are cut to complement each other. Everything fits like a puzzle; technically as well as aesthetically. It is up to each cyclist to follow the climate range guidelines and to experiment with the different ASSOS garments in order to find the perfect personal outfit for each specific riding season.
