Fabric Guide 2026

Understanding fabric types and weights is essential for making good purchases through the Hubbuycn spreadsheet. This guide explains the most common fabrics you will encounter and what the numbers mean.

GSM Explained

GSM stands for Grams per Square Meter. It measures fabric weight. In the Hubbuycn spreadsheet, GSM is the most reliable indicator of fabric quality. A higher GSM generally means a thicker, more substantial fabric. For t-shirts, 240-300 GSM is ideal. For hoodies, 400+ GSM is considered premium.

Cotton Types

The Hubbuycn spreadsheet lists several cotton types. Ring-spun cotton is softer and more durable than regular cotton. Combed cotton has shorter fibers removed, making it smoother. Pima and Egyptian cotton are premium variants with longer fibers. Check the fabric type column in the spreadsheet for these details.

Blends

Cotton-polyester blends are common in the Hubbuycn spreadsheet. They offer better shape retention and less shrinkage than pure cotton. The typical blend is 80/20 or 70/30 cotton to polyester. The exact blend percentage is listed in the spreadsheet for most items.

Synthetic Fabrics

For jackets and performance items, synthetic fabrics like nylon and polyester are common. The Hubbuycn spreadsheet lists denier ratings for nylon items, which indicates thickness. Higher denier means more durable fabric. For puffers, the shell fabric rating is as important as the fill.
