Men's Storm+ "12-Hour" RT Bibs

Size & Fit Chart

OVERVIEW: This is the inclement weather 12-Hour Bib™. Designed for ultra endurance events like the Transcontinental RaceTour Divide or Land’s End to John O’Groats, where weather and wet conditions can be a significant factor. Our development team worked for over two years with Italy's finest chamois makers at Elastic Interface® to perfect the ultimate long-distance pad, the Endurance Anatomic Super Air. Even more amazing is how water literally rolls off thanks to the bluesign® environmentally friendly, DWR (durable water repellency)  finished stretch fabric. Reflective leg grippers provide 360° safety in low-light conditions.

FABRICS & CONSTRUCTION: Guaranteed to provide unparalleled comfort for 12-hour activities, the Storm+ has been engineered with the one-of-a-kind Endurance Anatomic Super Air chamois, designed specifically to our demanding specifications. Built with all the same features you have come to love from the Endurance Anatomic 2 Carbon Flash chamois in our award winning Summit Raptor bibs, the new Anatomic Super Air is even lighter and more breathable. Plus, the unique perforated design allows for moisture transfer and quick drying. Using our proven Silhouette Articulation, the Storm+ shapes to your body in the riding position. You will be amazed at the water repellency of the Storm+ material. Water literally rolls off thanks to the bluesign® environmentally friendly, DWR (durable water repellent) finished stretch fabric. A breathable brushed fleece interior is cozy and comfortable against the skin. Reflective leg grippers from Plastotex®, another highly-respected Italian manufacturer, offer 360° safety in low-light conditions. 


The following OFF BODY inseam lengths were measured on a garment at rest. They may not exactly reflect the ACTIVE inseam length when the garment is being worn due to the combined effects of the 1) the riders's torso and femur length, 2) stretchiness of the material, and 3) the rider's leg musculature. 

S = 21 cm
M = 21.5 cm
L = 22 cm
XL = 22.5 cm
2XL = 23 cm

Pair with the Storm+ Hybrid Jacket and Arm Warmers for ultra-endurance, all-day comfort in wet and inclement weather conditions.

Measuring Tips 


Using a soft measuring tape, bring the tape across your back under each arm, around the front. For women, measure the widest point of the bust. For men, measure around the largest part of your chest.


Bend to one side to find natural indentation in torso. This is your natural waist. Run tape around waistline, keeping tape parallel with floor. 


Stand on a level surface with feet together. Measure around fullest part of hips and bottom (approximately 7" - 9" below waistline), keeping tape parallel with floor.
