Jamroc Dept. and Surf Trip Supply are both premium-priced streetwear brands, but they solve the "how will this actually fit and feel" problem in opposite ways — Jamroc publishes exact fabric weight on most heavyweight pieces, while Surf Trip Supply publishes a model's height and worn size on a good chunk of its catalog instead. We compared both live catalogs.
How we compared them
We pulled both brands' full live catalogs on August 30, 2026 — Jamroc Dept. (244 products) and Surf Trip Supply (50 products).
The quick verdict
Pick Jamroc Dept. if you want:
- ✅ Published fabric weight (GSM) — 400–530 GSM figures are common across the heavyweight line; Surf Trip Supply rarely publishes this
- ✅ A much bigger size range — 155 of 244 products reach 2XL, 19 reach 5XL, and 14 reach 6XL; Surf Trip Supply tops out at XL on 49 of its 50 products
- ✅ A far bigger catalog — 244 products versus 50
Pick Surf Trip Supply if you want:
- ✅ A model-height fit reference — a meaningful share of its catalog states a model's height and the size they're wearing, a feature Jamroc doesn't use
- ✅ California surf-culture design work — a different aesthetic entirely from Jamroc's Caribbean identity

Size range: the clearest gap
| Jamroc Dept. | Surf Trip Supply | |
|---|---|---|
| Reaches 2XL | 155 of 244 products | 1 of 50 products |
| Reaches 5XL | 19 of 244 products | 0 of 50 products |
| Reaches 6XL | 14 of 244 products | 0 of 50 products |
If you wear above an XL, Jamroc Dept. is by far the better-stocked brand of the two — Surf Trip Supply's entire catalog is built almost exclusively around a S–XL range.
Two different approaches to fit information
Jamroc Dept. answers "will this feel heavy or light" with a number: most of its heavyweight hoodies publish an exact GSM figure (400–530 is common, with one quarter-zip style claimed at 750 GSM). You know the fabric weight before you buy, though you still have to translate that number into what it'll feel like on you.
Surf Trip Supply instead answers "will this fit like it does in the photo" with a real reference point — a specific model's height and the size they're wearing, published on a meaningful share of its listings. It doesn't tell you fabric weight, but it gives you a size-to-body comparison Jamroc doesn't offer.
Price and catalog size
| Jamroc Dept. | Surf Trip Supply | |
|---|---|---|
| Tee price | $34–85 | $45–55* |
| Hoodie price | $120–165 | $75–98 |
| Total catalog | 244 products | 50 products |
*Surf Trip Supply's specific graphic tee styles were sold out across all sizes at the time we checked; the price reflects recently listed styles, not guaranteed current stock. Surf Trip Supply's hoodies actually run cheaper than Jamroc's — the opposite of the tee comparison.
