Bull-it (UK) and Denimotto (USA) both make AAA-class protected motorcycle denim, but the underlying technology differs. Bull-it uses Covec™, a proprietary single-layer aramid blend with strong hot-weather breathability and UK roots since 2008. Denimotto uses DuPont™ Kevlar® in both lined and single-layer constructions, priced lower with US-based support and made-to-order custom sizing. Choose Bull-it if you ride in hot/humid climates (UK, Australia, Southeast Asia) and want their established single-layer technology. Choose Denimotto if you want AAA protection at a lower price point with custom sizing options. Both are legitimate AAA-class protected denim brands.
Why this comparison matters
Bull-it and Denimotto often appear in the same "best protected motorcycle jeans" lists. Both certify under EN 17092 to AAA-class. Both target buyers who want jeans that look like normal denim but offer real abrasion protection.
The differences are meaningful: different fiber technology (Covec vs Kevlar), different geographic strengths (UK/Australia/EU vs USA), different price points, and different sizing flexibility. This article walks the comparison honestly — including where Bull-it is the better choice for a buyer.

Where Bull-it wins
1. Covec technology — proven single-layer aramid
Bull-it's Covec is a proprietary single-layer aramid blend, not Kevlar. It's been refined over more than 15 years and earned a strong reputation in UK and Australian riding communities specifically. For buyers who weight long-track-record technology over brand newness, Covec has the longer history in single-layer protected denim.
2. Hot-climate riding heritage
Bull-it is UK-based but built much of its reputation in Australia and Southeast Asia — hot-climate markets. Their single-layer construction reflects that origin: breathable, lightweight, designed for sustained heat. If you ride primarily in 80–100°F+ conditions, Bull-it's hot-weather pedigree is genuinely earned.
3. UK and Commonwealth distribution
For UK, Australian, New Zealand, and EU buyers, Bull-it has stronger local retailer networks than US-based brands. Local returns, local sizing reference points, and faster shipping all favor Bull-it in these markets.
4. Range of cuts and washes
Bull-it offers a broad range of fits (Easy, Tactical, Vintage Easy) and color washes (raw indigo, jet black, grey, light wash). For buyers who want style variety within the AAA-class category, Bull-it's lineup is broader than ours.
Where Denimotto wins
1. AAA protection at lower entry price
Denimotto's AAA-class jeans start at $130, vs Bull-it's typical $220+ entry point. For buyers who want certified protection without paying for premium positioning, our pricing is meaningfully lower.
2. Both lined and single-layer options
Bull-it commits to single-layer Covec across the line. Denimotto offers both lined Kevlar (warmer, more affordable, better for cold climates) and single-layer aramid options (cooler for hot climates). This gives buyers more flexibility to match construction to their actual riding conditions.
3. Made-to-order custom sizing
Denimotto's made-to-order custom service starts at $280 and accommodates tall, big-and-tall, petite, and athletic builds. Bull-it offers standard sizing only. For non-standard bodies, this is the difference between getting gear that fits and not.
4. US-based support and shipping
For US riders, Denimotto is local. US-based warranties, US shipping, US customer support, US return shipping. Bull-it ships from the UK with international shipping and customs complications for US returns.
5. CE Level 2 armor compatibility as standard
Both brands include CE Level 1 armor at the knees. Denimotto's pockets are sized for CE Level 2 upgrades from D3O, SAS-TEC, Knox, and Forcefield. Bull-it's pockets accommodate brand-specific armor; CE Level 2 upgrades require checking compatibility per product. See our CE Level 1 vs Level 2 guide.

Covec vs Kevlar — what's actually different
Worth understanding clearly because it's the technical heart of this comparison:
Kevlar (DuPont) is the best-known aramid fiber, used in motorcycle protective gear since the 1980s. Excellent abrasion resistance, heat-resistant (chars at ~450°C), but degrades under UV light, which is why it's most often used as a lining inside the denim.
Covec (Bull-it proprietary) is an aramid blend designed specifically for single-layer applications. The blend resists UV better than pure Kevlar, allowing it to be woven directly into the outer denim surface. The result is breathable single-layer protection. Bull-it claims their Covec material exceeds AAA-class requirements.
Functionally: both achieve AAA-class certification under EN 17092 when properly constructed. The EN 17092 class is the comparable metric, not the fiber name. A Bull-it jean and a Denimotto jean both certified AAA-class are roughly equivalent in tested abrasion protection.

AAA jeans, men's, regular cut
| Feature | Bull-it SR6 Tactical Slim | Denimotto Workshop Slim |
|---|---|---|
| EN 17092 class | AAA | AAA |
| Fiber | Covec single-layer | Kevlar single-layer (Workshop Slim) |
| Armor | Knee Level 1; hip optional | Knee Level 1 included; hip optional |
| Cut | Slim | Slim |
| Sizes | EU 28–38 | US 28–40 + custom MTO |
| Price | $260–300 | $160–200 |
Verdict: Bull-it earns its premium in hot-climate riding pedigree and UK/Australian reputation. Denimotto delivers equivalent AAA-class certification at meaningfully lower price with broader sizing.
Which brand is right for you?

| Are tall, big-and-tall, petite, or non-standard sizing | Denimotto (Custom MTO) |
| Want both lined and single-layer options to choose from | Denimotto |
| Ride in temperate or cold climates | Denimotto (lined options are warmer) |
| Want CE Level 2 armor upgrade compatibility | Either, but verify with Bull-it per product |
There's no universal winner. The right choice depends on geography, climate, sizing needs, and budget.
What both brands have in common
Both Bull-it and Denimotto are legitimate AAA-class protected denim brands certified under EN 17092. Both publish protection classes openly on product pages. Both work with reputable third-party testing labs. Both offer real protection, not marketing-only claims.
The motorcycle protective denim category is full of "Kevlar lined" jeans on Amazon that aren't certified and don't perform. Choosing between Bull-it and Denimotto is choosing between two genuinely tested options — the decision is about fit, value, and geographic match, not about whether the protection is real.
Honest disclosure
Denimotto wrote this. We've worked to keep it fair — used Bull-it's actual product names and specifications as published on their site as of May 2026, recommended Bull-it where they genuinely better fit a rider's needs, and acknowledged their hot-climate pedigree honestly. If you choose Bull-it based on this comparison, that's a legitimate outcome.

FAQ
- Is Bull-it better than Denimotto?
- Neither is universally better. Both make AAA-class certified protected denim. Bull-it uses Covec single-layer technology with strong hot-climate pedigree, priced $220–320. Denimotto uses Kevlar in both lined and single-layer constructions, priced $130–280, with US-based support and made-to-order custom sizing. Choose Bull-it for hot-climate riding and UK/Australian markets; Denimotto for US riders, value, and non-standard sizing.
- What is Covec, and is it the same as Kevlar?
- Covec is Bull-it's proprietary aramid blend, designed specifically for single-layer applications. It's similar to Kevlar in protective function but engineered to resist UV better, allowing single-layer use. Kevlar (DuPont) is the more widely-known aramid, typically used as a lining. Both achieve AAA-class certification when properly applied.
- Which is more protective, Bull-it or Denimotto?
- Both achieve AAA-class certification under EN 17092 — the highest abrasion class. Tested abrasion protection is functionally equivalent. Differences are in construction approach (Bull-it commits to single-layer Covec; Denimotto offers both single-layer Kevlar and lined Kevlar), armor compatibility, and feature sets.
- Are Bull-it jeans worth the price?
- For hot-climate riders, UK/Australian/EU riders with local retailer access, and buyers who value the long-established single-layer Covec technology — yes. For US riders, value-conscious buyers, or non-standard sizing needs, Denimotto delivers equivalent AAA protection at a lower price.
- Can I get Bull-it in custom sizes?
- Bull-it offers standard EU/UK sizing ranges. Custom made-to-order is not a standard service. For non-standard sizing (tall, big-and-tall, petite, athletic), Denimotto's custom MTO from $280 is the cleanest path.
- Where is Bull-it manufactured? Where is Denimotto manufactured?
- Bull-it is UK-based with manufacturing in Asia. Denimotto is based in Virginia, USA, with manufacturing partnerships. Both ship internationally; for US riders, Denimotto is local with straightforward returns. For UK/EU riders, Bull-it is local.
