What It Is

Endurance-level comfort for every ride with Castelli's most comfortable seat pad.
Progetto X² Air Seamless

MAXIMUM TECHNOLOGY FOR SUPREME COMFORT.Constructed in two components, each dedicated to a specific purpose, that together create the most comfortable seat pad on the planet.Skin Care LayerSeamless, bacteriostatic layer made to adapt to the shape of your body and saddle without any folds in the fabric. Cushioning LayerSeamless Integrated Technology (S.I.T.) Perforated Viscous Comfort Zone.

The main story of this short is the use of our renowned top-of-the-line Progetto X2 Air Seamless seat pad in an otherwise traditional short, but in fact every little detail has been obsessed over to ensure your comfort on your next long endurance ride. A great pad is useless without great fit. The seams are placed around the hip area to create a perfect shape on the bike. The Endurance Evolution fabric has a soft hand while providing good compression and excellent moisture management. And it's all held in place with the amazingly comfortable GIRO3 leg gripper. This short offers exceptional value and is ready to deliver lasting comfort on your longest rides.

280km and my butt is okay

13/05/2024

Bought this because I needed a much better chamois for my endurance training. This was waaaaaaay more comfortable.

Following the sizing chart and gbuying XL bibs was perfect for me.
I usually wear a size M for my normal clothing size.

Great quality, but sizing is way off

03/08/2023

The quality of these bibs doesn't disappoint, the material feels great and provides adequate support, especially if you choose a smaller size (see my comment later on sizing). The chamois is really comfy for longer rides, which is what I was looking for. I just got these so I don't know how they hold in time, with washing and everything. The only disappointment is the sizing: I usually get bibs in M (5'9" 75kg) but with Castelli I sized up, so I ordered L. They are incredibly small, so I recommend sizing 2 up if you want a good fit (supportive, not loose)

Sizechart needs to be updated

Hip measurements doesn't correspond. I have hip measurement 95 cm and ordered size L. Didn't fit. Changed to XL, but did't fit either. Next I try size XXL which has said to fit hip measurement of 108 cm. Hope this will do.

Nice bib but go 1 size up!

05/07/2023

Well-made bib, however sizes are misleading for Europe - I'm between L/XL with my 186 cm 89 kg, but took this one in XXL (after reading feedback for another Castelli bib - thanks for that!), so what I see is that XXL ir really like L/XL, that is tight on me. Overall impression after 1st use - chamois pad is not very thick, especially thin in front part (this improves air inflow to your genitals), and surface is very soft-touch . Shoulder strips with XXL are Ok and comfortable for my 186 cm height, but not any loose on my small shoulders. Overall - very good quality, but watch for the right size for you, don't hesitate going size up.

Does the ENDURANCE 3 BIBSHORT have a thicker chamois compared to other bib shorts?

Hi Nelson! The Endurance 3 Bibshort has the Progetto X2 Air Seamless, the same used on all our Rosso Corsa bibshorts and bibtights.

Perfetto

29/03/2024

Ho preso il primo pantaloncino Castelli nel 1997. Nel corso degli anni ho provato altre marche, ma alla fine sono ritornato da Voi. Ormai sono anni anni che li sto utilizzando. Per la mia corporatura, semplicemente perfetto.

Top Sitzpolster

12/05/2024

Das Sitzpolster ist Top. Die erste Fahrt ging über 4 h und was soll ich sagen, den Popo ging es gut.
Oft liest man, das man 2 Größen größer bestellen soll, das würde ich nicht so bestätigen.
Ich trage normalerweise M, bin 178 cm groß und 75 kg schwer.
Der Größenrechner auf dieser Seite ist eine gute Hilfe. Beim mir kam nach all meinen Angaben dann auch eine M als Empfehlung raus.
ABER mit dem Hinweis "etwas eng".
Falls das so ist wählt die nächst größere Hose.
Mit der M lässt es sich zwar fahren, ist aber wirklich etwas (zu) eng. ;-)

Incredibilmente ottimo

25/06/2023

Primo acqusto da Castelli.
Usati il primo giro (medio) sembrano come tanti altri ....
Provati nel secondo giro (250 Km 10,30 h) ottimi ... nessun dolore , ne abraiioni da sfregamento ne altro. incredibile!!
Usati ieri per il giro più lungo (300 Km 13 h) meraviglia, han tenuto fino alla fine senza fastidi.
Complimenti.
Penso che oltre ci siano problematiche dovute all'eccesiva permanenza in sella ma per me questo è il massimo che posso fare ed aspettarmi.
