Troy Lee Designs Jackets
Troy Lee Designs jackets sit at the sharper end of MTB outerwear - gear built around the reality that you're going to be moving hard, not standing still. Whether you're chasing enduro stages on the Quantocks or grinding a wet fire road in the Tweed Valley, TLD's jacket range is designed to keep the weather out without turning you into a mobile sauna. The moto world shaped the brand's thinking around protection and mobility, and you can feel that logic in how these jackets are cut - forward-leaning, built for a rider who's actually riding.
The range covers proper ground. Lightweight DWR-coated windbreakers handle the unpredictable British shower - the kind that arrives halfway through your climb and disappears before the descent. Step up to the heavier waterproofs and you're looking at taped seams, waterproof membranes, and the sort of build quality that doesn't flinch at a Welsh autumn. Articulated sleeves stop fabric bunching when your arms are stretched forward, and helmet-compatible hoods mean you're not choosing between head coverage and your lid. For riders who don't want bad weather to decide when the ride ends, TLD's outerwear is worth a serious look.

Fabric Tech and What It Actually Keeps Out
Not all TLD jackets are doing the same job, so it's worth knowing where the line sits between a windbreaker and a proper waterproof. The lighter end of the range uses Teflon EcoElite DWR coating - a durable water-repellent finish that causes rain to bead and roll off the outer fabric. It handles splashes and brief showers well, and because there's no heavy membrane, breathability stays high. Good for those days when the forecast looks borderline and you want something that packs away to nothing.
The heavier-duty options - the Descent line being the flagship - run a 10k/10k waterproof/breathability rating as standard, with higher-spec versions reaching 20k/20k. Those numbers mean the fabric can handle sustained rain without saturating, while still letting water vapour escape as you work. Fully taped seams close off the stitch lines that membranes alone can't seal, and YKK water-resistant zippers stop the obvious weak points from letting water track in. On a steep UK climb where you're generating real heat, the better-rated jackets earn their keep - you're not just staying dry from the rain, you're not cooking yourself from the inside either.
Pit zips and chest vents appear on some models for exactly this reason. On a punchy Peak District climb in October, that mechanical venting is the difference between a jacket you want to wear and one you stuff in your pack at the first switchback.
How TLD Jackets Fit and Which One's for You
TLD cuts its jackets around a ride fit - which means the proportions assume you're bent over bars, not standing upright in a shop. Articulated sleeves are pre-shaped so they don't ride up when your arms are extended forward; that matters when you're descending and you don't want cold air funnelling up your forearms. The drop tail extends coverage at the rear, which is genuinely useful when rear-wheel mud spray is a factor - and in the UK, it usually is.
The helmet-compatible hood fits over a full-face or trail lid with drawcords to cinch it down, so you're covered on long exposed ridgelines without the hood catching wind like a sail. Sizing runs fairly true across the range, but if you're planning to layer over a chest protector or back armour, go a size up. Worn over a Troy Lee Designs base layer, the standard sizing works well for most riders.
If core-only wind protection is what you're after - no sleeves, no faff - the TLD Gilets page is where to head. For post-ride warmth and casual wear, the Hoodies and Sweatshirts ranges cover that ground better than a trail jacket will.
Layering Smart and Keeping the DWR Working
A TLD jacket performs best when you treat it as a shell, not a standalone insulator. In autumn - the kind of riding where it's 8°C and drizzling by the time you reach the trailhead - pair a windbreaker over a moisture-wicking TLD jersey and you've got a simple two-layer system that breathes without leaving you damp underneath. Drop into winter and a waterproof shell over a thermal mid-layer makes more sense; the membrane does the weather work while the mid-layer manages your warmth.
The thing most riders get wrong is washing. Machine-washing with standard detergent gradually clogs the DWR coating - the fabric stops beading water and starts wetting out, which tanks both water resistance and breathability. Use a technical cleaner like Nikwax Tech Wash instead, and wash on a gentle cycle. Tumble dry on low or iron on a low setting afterwards - heat reactivates the DWR. If the jacket is wetting out even after a wash, it's time to reproof with a spray-on DWR treatment like Nikwax TX.Direct. You'll know it's needed when rain stops beading and starts soaking in.
Storage matters too. Hanging a packable jacket compressed for months stresses the membrane. Store it loosely, and if it's been a muddy one, rinse it off before it dries - dried mud left in the fabric works against the coating over time. Pair the jacket with TLD waterproof trousers or MTB shorts to round out the system for longer days in genuine wet weather.
Troy Lee Designs Jackets FAQs
Are Troy Lee Designs jackets fully waterproof?
It depends on the model. Jackets like the Descent use a 10k/10k waterproof membrane with taped seams - designed to handle sustained heavy rain. The lighter windbreaker options rely on a DWR coating, which handles showers and splashes well but isn't rated for prolonged downpours. Check the waterproof rating before you buy if proper wet weather protection is the priority.
How do Troy Lee Designs jackets fit for mountain biking?
TLD uses a ride fit - articulated sleeves, a drop tail, and a cut that assumes you're on the bike rather than standing around. Sizing is generally true to fit over base layers and jerseys. If you're planning to wear body armour underneath, go a size up to avoid restricting your movement in the attack position.
Can I pack a TLD jacket into my riding pack?
The windbreaker and lighter trail jackets compress down easily into a hip pack or frame bag - genuinely useful when the weather could go either way. Heavier waterproofs like the Descent are bulkier but will still roll up into the main compartment of a standard MTB hydration pack without too much hassle.
