Hoodie Weight Guide: What GSM Means in the Fishgoo Spreadsheet
Fabric weight changes everything about how a hoodie feels and drapes. Here is how to read GSM data in our sheets.

What Is GSM and Why It Matters
GSM stands for grams per square meter and it is the standard way to measure fabric weight. In the Fishgoo Spreadsheet, the GSM column tells you how heavy or light a hoodie will feel before you buy it. Lower GSM around two hundred to three hundred means a lighter, more breathable layer suitable for spring or indoor wear. Higher GSM above four hundred indicates a thick, warm hoodie that holds its shape better and feels more substantial.
GSM also affects how a hoodie drapes on your body. Lightweight hoodies cling and flow, which can look relaxed but also less structured. Heavyweight hoodies stand away from the body, creating cleaner lines and a more defined silhouette. Neither is better by default, but knowing the GSM helps you pick the right piece for your climate and style preference.
Another factor influenced by GSM is shrinkage behavior. Higher GSM fabrics often shrink less because the fibers are packed more tightly. Lower GSM fabrics can shrink noticeably after the first wash, which changes both the fit and the drape. Our spreadsheet includes a shrinkage note column that pairs with GSM data to give you a complete picture of how the hoodie will change over time.
Typical GSM by Style
Comparing GSM Across Styles
Different hoodie styles target different GSM ranges. Vintage wash hoodies often sit around two hundred fifty GSM because the washing process thins the fabric slightly. Streetwear blanks usually aim for four hundred to five hundred GSM for that oversized, boxy structure. Athletic hoodies might drop below two hundred GSM to prioritize stretch and moisture movement.
Our Fishgoo Finds break this down by style so you do not compare a vintage wash piece to a heavyweight blank and feel confused. We also note whether the GSM is pre-wash or post-wash, since some hoodies shrink and become denser after the first laundry cycle. This matters if you are ordering for an exact fit and weight feel.
Style-specific GSM expectations also help you avoid disappointment. If you order a streetwear blank expecting a light layering piece, the four hundred plus GSM weight might feel bulky and unwieldy. Conversely, if you order a vintage wash hoodie expecting winter warmth, the two hundred fifty GSM weight will leave you cold. Our style tags prevent these mismatches by setting expectations before you buy.
Warmth Ratings
How GSM Relates to Warmth
Warmth is not only about GSM, but GSM is a strong predictor. A four hundred fifty GSM cotton fleece hoodie will keep you warm in cool autumn weather. A two hundred GSM French terry hoodie is better for layering under a jacket rather than wearing alone in cold conditions. We pair the GSM number with a warmth note in our sheet to make this intuitive.
Other factors like lining type and drawstring thickness also play a role. A hoodie with a sherpa lining will feel warmer than its GSM alone suggests. We include a lining note column for this reason. By combining GSM, lining, and warmth tags, you get a complete picture without needing to touch the fabric yourself.
For buyers in variable climates, we recommend building a hoodie rotation across GSM ranges. A two hundred GSM hoodie for indoor and mild weather, a three hundred fifty GSM hoodie for transitional seasons, and a four hundred plus GSM hoodie for winter. This layering strategy gives you more outfit combinations than relying on one heavyweight hoodie year-round.
