Our models typically wear US Size 2-4 or Australian Size 6-8, X-Small, Small, or One-Size garments.
On each product page, we provide the model's measurements and what size she is wearing to help guide you.
You can refer to the charts when selecting sizes but please note that sizes cannot be guaranteed and might vary slightly between brands.
If you need any advice about sizing, please feel free to drop us a line at: service@sunnoss.com
The measurements in the description of individual products are taken only across the front side of the garment, not around the circumference (e.g. chest and waist).
If you can't find a completely satisfactory size in our size chart, don't worry! Feel free to contact us anytime at service@irispetal.com or through our online customer service. Our team is more than happy to provide personalized advice, recommend alternative styles, or assist with customization needs. Your comfort is our top priority!

Why Can't Light Be Aero?
The next-gen Specialissima says no to compromise, giving you the very best tool for mountains and steep gradients. The lightweight, aero-optimised frame and proprietary componentry ensure you can excel on the flat roads and technical descents that come before and after the climb.
Light
The overall weight of the Speciallisima is 6.6Kg, with a variation of (+/-) 5%. Achieving this low weight meant strategic redistribution of material from the rear of the bike to the front, with super-fine seat stays and thinner chain stays, while also amping up the shape of the head tube to create the more aerodynamic front-end.
Aero
Compared with the previous generation, enhancements made to the Specialissima add up to 8.7 seconds saved for a rider doing 200 watts on a 10 km climb at 6%.
On the flat for 40km, 31.9 seconds are saved at 200 watts. For elite climbers doing 30km/h on a 6% gradient, 3.6 watts of effort are saved by the Specialissima's design.
Pushing the Threshold
We call the tipping point where an all-rounder can outperform an aero bike "The Threshold". The data proves the next-gen Specialissima hits Threshold significantly sooner than the previous generation.
In comparison with the Oltre RC, and in the hands of a pro cyclist pushing 420w, the Specialissima RC becomes the best choice for climbing on gradients above 6.2%. This is due to the aerodynamic optimisation of the Specialissima, along with its excellent stiffness-to-weight, and low overall weight.
For a well-trained expert doing 300w, the Threshold is reached at 4.9%. For a medium-level amateur producing 250w, the Specialissima hits Threshold at 4.2%.
For Mountain Courses
Its stiffness-to-weight enables the Specialissima to excel on climbs, while the redesigned aerodynamics ensure it can also support you to be faster on the flat valley roads and winding descents that come before and after.
