Love love love the colour! Runs a bit small. I'm 5'4" and 125 pounds. Usually get small, but took the medium. Padding is the thickest I've owned, but worked ok yesterday cycling 65km.

Extremely comfortable cycling short and looks great . Excellent padding (chamois) that contributes to comfort without hampering movement. Like most Castelli products runs small, you need one size larger than average product.

The chamois in these shorts is really awesome! The fabric is so soft and the cushioning is spot on. The outer fabric of the shorts themselves is a bit scratchy and not as stretchy as I usually prefer but I don't notice it once they are on. These shorts feel good and look good.

Easy to navigate website and was guided through what size would fit using other purchase data when buying for my wife’s birthday, it was spot on too.Package arrived on time and was emailed the delivery slotWill definitely use Tredz again
Very comfortable running shorts
Great length, super breathable and light, not too tight and simple design.
Girlfriend has a small waist (27) and larger hips (38) and a large fit well around the hips, but was a bit loose around the waist. She typically does not order large pants though, hence the "running small" pick. Though she doesn't mind that since they do not move when she's riding since they compress well to her thighs. All-in-all, give these a test fit before riding in them, because the chamois and look is really good.
Positive transaction
This is a high quality short, but the material is quite substantial and could be too thick for everyday riding. It would work well in situations where abrasion is expected. The shorts are also on the longer side in the leg / inseam.
