The Pas Normal Studios Men's PAS Mechanism Thermal Long Bibs are race-focused thermal cycling tights designed for fast training and longer efforts in cold, variable conditions. Crafted in Italy from M.I.T.I. SuperRoubaix fleece fabric, they combine effective insulation with high stretch and abrasion resistance for unrestricted movement throughout demanding winter rides.

A C0 DWR treatment adds protection against light rain and road spray while maintaining the breathability of the fleece construction. Ergonomically shaped legs follow the riding position closely, while an internal hem elastic with a silicone grid gripper keeps the tights securely positioned without restricting movement.

Fleeced shoulder straps add warmth around the upper body while retaining breathability through their mesh structure. A four-layer chamois with quick-drying antimicrobial membranes provides support and moisture management during longer efforts, while reflective detailing improves visibility in low-light winter conditions.

The Pas Normal Studios Women's PAS Mechanism Thermal Long Bibs are race-focused thermal bib tights designed for fast training and longer efforts in cold, variable conditions. Built around the streamlined Mechanism platform, they combine high-stretch M.I.T.I. SuperRoubaix fleece with lightweight weather protection and a four-layer chamois for sustained comfort through winter riding.

The fleeced SuperRoubaix fabric provides effective insulation while maintaining the stretch required for an aggressive position on the bike. Its high abrasion resistance supports repeated use through demanding winter conditions, while a C0 DWR treatment helps repel road spray and light precipitation without turning the bibs into a fully waterproof layer.

Fleeced shoulder straps add warmth around the upper body, while their mesh structure maintains breathability and stretch beneath additional winter layers. An articulated construction follows the riding position closely, combining thermal protection with the freedom of movement required during harder efforts.

A highly technical development for the harshest conditions. Perfect for fast-paced training and racing through the deepest of winter. The PAS Mechanism Deep Winter Long Bib features a revised fit around the knee and lower leg as well as the waist. The Windtex Pro Membrane used in the 3-layer main fabric adds a stretchable feel, creating an optimal fit. The advanced back of the fabric uses a brushed fleece in a grid structure for extra insulation and warmth, while still allowing you to breathe. The soft elastic straps and mesh back panel create the best possible conditions for your choice of base layer and outer layers to work with you.

Temperature
The bibs are optimised for winter training below and around 0 degrees.

Intensity
The bibs can be used for both low intensity and high intensity rides. Use them on chilly training rides in between seasons or use them in CX/gravel races during the winter season when the temperature drops below 0 degrees celcius.

Insulation
The bibs combines light and advanced 2 and 3-Layer Schoeller fabrics for both protection and insulation.

Wind Protection
Without adding bulk, the extra layers of fabric gives your muscles protection from the wind.

Water Protection
The bibs are water protected in key areas and will keep you protected from light showers.

Breathability
The bibs are made to protect to you from the elements and keep you warm. This compromises breathability properties slightly. However, perspiration is still allowed in order to get rid of excess heat.

Fit
Optimised for road riding, the bibs has inherited the tight fit from the Mechanism collection.
