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.

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.
