Jamroc Dept. vs Farm Brand

Which one actually gives you more fabric for your money?

I have not personally tested every product here — these picks are based on manufacturer specifications, expert sources, and analysis of verified customer reviews. See our methodology below.

These two brands are almost never compared, and there’s a mundane reason why: they measure fabric in different units. Jamroc Dept. publishes GSM (grams per square metre). Farm Brand publishes oz (ounces per square yard). Put their product pages side by side and the numbers are incomparable — 530 versus 8.3 tells you nothing.

So we converted all of it. 464 products across both catalogs, every published weight normalised to GSM.

The result splits cleanly, and neither split is close.

First, the conversion you need

1 oz/yd² ≈ 33.9 GSM. That’s it — a straight unit conversion, not an estimate.

So when Farm Brand lists a hoodie at 8.3 oz, that’s 281 GSM. When Jamroc lists one at 530 GSM, that’s 15.6 oz. Now they’re comparable.

For reference, here’s how the trade generally reads these numbers:

Hoodies: Farm Brand wins on price per gram, decisively

Every figure below read from the brands’ own product data on July 23, 2026.

Farm Brand hoodies

Jamroc Dept. hoodies

Cost per gram of fabric weight:

• Farm Brand Just Right Surf — 281 GSM at $40 = $0.14 per GSM
• Jamroc Essential Heavyweight — 400 GSM at $135 = $0.34 per GSM
• Jamroc I and I — 530 GSM at $165 = $0.31 per GSM

Farm Brand delivers roughly twice the fabric weight per dollar. If your goal is “a genuinely substantial hoodie for the least money”, that is the answer, and it isn’t marginal.

⚠️ But read the fibre column before you get excited about that 417 GSM. Farm Brand’s heaviest hoodie is heavy because it’s 100% polyester with a sherpa lining — the weight comes from a bonded fleece layer, not from dense knit cotton. Jamroc’s 530 GSM is 100% cotton. These are different garments that happen to share a number. A sherpa-lined polyester zip-up is warmer; a 530 GSM cotton pullover holds structure and shape in a way fleece does not.

The honest comparison is Farm Brand’s cotton-blend hoodies at 271–281 GSM against Jamroc’s 400–530 GSM cotton. Jamroc is meaningfully heavier. Farm Brand is meaningfully cheaper. Neither is “better” — they’re aimed at different buyers.

T-shirts: Jamroc wins, and the gap is enormous

This is where the comparison stops being close.

Farm Brand’s Plain T-Shirt is $24 at 142 GSM. Jamroc’s Di Goat Crowned Vintage Heavyweight Tee is $85 at 430 GSM.

142 GSM is a light summer tee — thin, close-draping, often slightly translucent in pale colours. 430 GSM is triple that, and behaves like a completely different garment: it holds a boxy shape, doesn’t cling, and doesn’t go see-through.

Farm Brand does offer a few heavier exceptions — the Soft-Washed Hoodless Pullover at 7.0 oz (237 GSM, $45) and the Soft-Washed Midweight Long Sleeve at 6.1 oz (207 GSM, $38) — but across the tee range, 4.2 oz is the default by a wide margin.

If you want a heavyweight tee, Farm Brand essentially does not sell one. That’s not a criticism; it’s a different product philosophy. But it decides the question.

Range, sizes and availability

Two things stand out.

Farm Brand has deeper stock and better spec coverage. 4,411 in-stock variants against 2,820, and 184 of 186 products state fibre content. Nearly every Farm Brand item runs a full XS–2XL grid.

Jamroc owns the extended sizes. 96 styles reach 3XL or beyond, against 14. Above 3XL, Farm Brand effectively has nothing.

⚠️ One thing to be careful about

The brand’s name is Farm Brand USA — but only 3 of its 186 products actually say “Made in USA” in their descriptions. The name is not a manufacturing claim about the catalog. If country of origin matters to your purchase, check the individual product page rather than assuming from the brand name.

Who should buy which

Buy Farm Brand if:

• ✅ You want a real hoodie under $50 — several sit at 271–281 GSM for $40–58
• ✅ You want matching joggers or sweatpants (Jamroc doesn’t sell them; Farm Brand has 23 styles)
• ✅ You want a lightweight tee for warm weather at $24–35
• ✅ You want the best odds your size is actually in stock

Buy Jamroc Dept. if:

• ✅ You want a genuinely heavyweight tee — 310–430 GSM, which Farm Brand doesn’t offer
• ✅ You wear above 3XL, or below XS
• ✅ You want 400–530 GSM cotton hoodies and accept paying $135–165 for them
• ✅ You want Jamaican-designed graphics specifically

Who should NOT buy from either

• ❌ You want heavyweight cotton on a budget. Farm Brand’s cheap hoodies are mid-weight; Jamroc’s heavyweights start at $135. That combination doesn’t exist here.
• ❌ You need a specific style above 3XL. Only Jamroc goes there, and only on some styles.
• ❌ You’re buying a gift without knowing their size or fit preference. Between Jamroc’s oversized cuts and Farm Brand’s crops and onesie dresses, guessing will go wrong.
• ❌ You want country-of-origin certainty across a whole catalog. Neither brand provides it at catalog level.

Frequently asked questions

Is Jamroc or Farm Brand better quality? Neither publishes enough to answer that outright. On the one metric both do publish — fabric weight — Jamroc’s garments are heavier, and Farm Brand’s are cheaper per gram. Weight is a proxy for substance, not for stitching or durability, and we have not handled either brand’s garments.

How do I compare oz to GSM? Multiply ounces by 33.9. A 6 oz tee is about 203 GSM; a 10 oz hoodie is about 339 GSM.

Why is Farm Brand’s 417 GSM hoodie cheaper than Jamroc’s 400 GSM one? Because it’s a different construction: 100% polyester with a sherpa lining rather than dense knit cotton. Fleece and lining add weight cheaply. Compare like fibre with like fibre.

Which has more sizes? Jamroc, at both ends — 2XS through 6XL, with 96 styles at 3XL or above. Farm Brand runs XS–2XL on almost everything, with 3XL on 14 styles.

Does Farm Brand sell heavyweight t-shirts? Not really. The overwhelming majority of its tees are 4.2 oz (142 GSM). Its heaviest short-sleeve option is the Soft-Washed Hoodless Pullover at 7.0 oz (237 GSM).

Is Farm Brand made in the USA? Only 3 of 186 products state that. The “USA” in the brand name is not a claim about the whole range.

Which is better value overall? For hoodies, Farm Brand, by roughly 2× on fabric weight per dollar. For tees, Jamroc, because Farm Brand doesn’t compete in the heavyweight category at all.

Do the numbers on this page change? Yes — prices and stock move constantly, and both brands add styles. Everything here was read on July 23, 2026. Check current listings before ordering.

Methodology and limitations

We read the complete published product data for both brands on July 23, 2026 — 278 Jamroc Dept. products and 186 Farm Brand products, 464 in total. From those we extracted every published fabric weight (78 Jamroc products in GSM, 97 Farm Brand products in oz), fibre content, price, and size availability, then converted all weights to GSM at 33.906 g/m² per oz/yd².

We have not physically handled either brand’s garments. Fabric weight, fibre content, price and size availability are verifiable from published data. Stitch quality, shrinkage, colour accuracy and how either brand wears after a year are not — and we make no claim about them.

The per-GSM cost figures are arithmetic on published numbers, not a quality judgement. A heavier garment is not automatically a better one.
