For first time buyers of cycling apparel it is important to note that most cycling jerseys and shorts run smaller than regular street clothes (especially in the larger sizes). And it is also common for different brands to sometimes fit differently from each other.
Each of our individual listings contains sizing info for that particular brand/model. Normally this would include a size chart and/or more detailed sizing info.
Just in case a buyer is not satisfied with the fit of any item they receive from us, we do offer a 60-day return policy for either a size exchange or refund.
Here are a few other tips and observations regarding cycling jersey sizing:
1) Usually, but not always, when a buyer is choosing between two different sizes, the bigger one is more often than not, the better choice.
2) We get back about 5%-6% of our jerseys for size exchanges. Of these that are returned, overall about 2/3 want a larger size and 1/3 want a smaller size. But if we break that down a little further, buyers of 3X, 4X and 5X are more likely to return for a larger size than buyers of M, L, XL.
