Five Ten Jackets
Five Ten MTB Jackets bring the same no-compromise attitude that made the brand's shoes legendary on everything from Yosemite granite to Hardline's gnarliest chutes. Now backed by Adidas's textile muscle, the range layers RAIN.RDY waterproofing and Primeblue recycled materials into shells that look casual enough for the pub but hold their own when you're threading wet roots in Hamsterley. You're getting on-bike cuts - helmet-compatible hoods, drop tail hems, cuffs that won't snag levers - wrapped in fabrics that wick hard on the climb and shed drizzle on the descent. It's technical outerwear that doesn't shout about it, which suits the rider who'd rather let the riding do the talking. Whether you need a packable windbreaker for shoulder-season loops or a full 2.5-layer shell for Scottish winters, Five Ten's approach balances function with a relaxed aesthetic that works off the bike too. Sustainability isn't an afterthought either; Parley Ocean Plastic threads its way through the Primeblue constructions, so you're keeping plastic out of the sea while keeping rain off your back.

Material Science: RAIN.RDY and Primeblue Explained
RAIN.RDY is Adidas's proprietary waterproofing system, and it's the backbone of Five Ten's wet-weather shells. The All-Mountain Rain Jacket uses a 2.5-layer fabric construction: an outer face fabric treated with a non-PFC DWR finish, a waterproof-breathable membrane bonded in the middle, and a lightweight protective layer inside. That setup blocks wind and rain while channelling moisture vapour away from your skin, so you're not brewing in your own steam halfway up a Peak District climb. Hydrostatic head ratings sit comfortably in the 10,000mm-plus zone for the full waterproof models, which is more than enough for a day in the Lakes when the weather can't decide what it's doing.
Four-way stretch is woven into the fabric too. Matters when you're reaching for the bars in a steep chute or twisting through tight singletrack. The Primeblue material is where the sustainability angle comes in - it's high-performance recycled polyester made in part with Parley Ocean Plastic, intercepted from beaches and coastal communities before it hits the ocean. You're not sacrificing durability for the eco credentials; the abrasion resistance holds up to pack straps and the occasional bramble encounter on Welsh trail centre descents. If you're after something lighter, the WIND.RDY windbreakers dial back the waterproofing in favour of breathability and packability, ideal for spring mornings in Surrey Hills when it's dry but brisk.
On-Bike Fit and MTB-Specific Features
Five Ten jackets follow a regular fit that's cut for layering. You can slip them over a jersey and elbow pads without feeling like you're wrestling a sausage skin, but they're not so baggy that fabric flaps around when you're moving fast. The hood design is key - it's articulated to fit over a full-face or trail helmet, with enough volume adjustment via elastic or drawcords to keep it snug when you're descending and the wind's trying to peel it back. No point having a hood that flies off the moment you point downhill.
Cuffs are elasticated or fitted with low-profile closures that won't catch on brake levers mid-corner. Drop tail hems extend coverage at the back, so when you're in the attack position - weight over the rear, hips back - you're not exposing a stripe of lower back to roost and spray. Pockets sit high enough that hip belts on hydration packs don't block access, and some models feature chest or sleeve stash pockets for trail snacks or a phone. It's the sort of detailing that only makes sense when you've spent time watching riders actually use the kit. If you're comparing fit philosophy, Endura jackets tend towards a more tailored race cut, while Five Ten leans into that relaxed, freeride silhouette that pairs well with Five Ten's casual tees and flannels when you're off the bike.
When to Wear What: Matching Jackets to UK Conditions
Wind jackets are your spring and autumn workhorses. They pack down small, weigh next to nothing, and block that cutting breeze that sneaks through a jersey on early-morning rides across the Pennines. The WIND.RDY models feature a DWR finish, so light drizzle beads off for a while, but don't expect them to hold up in a proper downpour. Think of them as insurance against the unpredictable - chuck one in your pack and forget about it until the clouds roll in.
Full 2.5-layer rain jackets come into their own from October through March, or any time you're riding in Scotland where rain is less a forecast and more a baseline condition. The sealed seams and RAIN.RDY membrane mean you stay dry through hours of persistent wet, though breathability becomes the trade-off you manage with pit zips or by cracking the front zip on climbs. High-output efforts - think steep fire-road slogs or repeated uplift laps - will still generate heat, so layering underneath matters. A lightweight merino base and a thin insulating mid-layer usually does the job without turning you into a mobile sauna.
For dry but cool days, the flannel-style technical shirts bridge the gap between casual and performance. They're not jackets per se, but they layer under a shell or work solo when temperatures hover around 10 - 15°C and the trails are dusty. Riders looking at similar versatility might also consider 7mesh jackets, which lean heavily into breathability, or Alpinestars jackets if you want a more moto-inspired aesthetic with similar technical chops.
From Yosemite Granite to Trail Centre Grit
Five Ten started life making sticky rubber for climbers tackling Yosemite's big walls in the 1980s. That Stealth rubber eventually migrated to flat pedals, and the brand became synonymous with downhill and freeride mountain biking through the 2000s. Riders trusted the shoes because they stuck when it mattered - no slip, no drama. When Adidas acquired Five Ten, the apparel line expanded, drawing on that rugged, functional ethos and pairing it with Adidas's textile R&D. The jackets carry that same durability mindset: reinforced zones, robust zips, fabrics that don't shred the first time you brush a gorse bush on a Quantock Hills descent.
It's not about heritage for heritage's sake. The construction reflects decades of feedback from riders who push kit hard. Seams are bar-tacked at stress points, hem adjusters are simple and glove-friendly, and the cut assumes you'll be moving dynamically rather than standing still. If you're after outerwear from brands with a similar pedigree in gravity disciplines, Fox jackets and Dirtlej's poncho-style shells also cater to riders who prioritise function and durability over fashion-forward cuts.
Pros and Trade-Offs
Pros: RAIN.RDY waterproofing delivers reliable protection without the crinkly feel of budget shells; Primeblue recycled materials let you ride with a lighter environmental footprint; MTB-specific fit details - helmet-compatible hoods, drop tail hems, lever-friendly cuffs - show genuine trail focus.
Cons: Breathability on full waterproof models can lag behind dedicated high-end shells from Castelli or Assos during sustained climbs, though pit zips help manage that; the relaxed fit won't suit riders chasing an aero silhouette or race-tight aesthetic; colour and style options lean casual, which might not appeal if you prefer bold, technical looks.
Answering Common Questions
Are Five Ten jackets waterproof? Models featuring RAIN.RDY technology use a 2.5-layer construction with sealed seams to provide full waterproofing, so yes, they'll keep you dry in persistent rain. Lighter windbreakers rely on a DWR coating for water resistance rather than full waterproofing, so they'll handle drizzle but not a deluge. Check the spec to see which tech the model uses.
How do Five Ten jackets fit compared to Adidas? Five Ten apparel follows standard Adidas sizing but is cut specifically for mountain biking. Expect a regular fit that allows room for layering and elbow pads without being overly baggy. If you normally wear a medium in Adidas casual gear, a medium Five Ten jacket should fit similarly, just with longer sleeves and a drop tail for on-bike coverage.
What is Five Ten RAIN.RDY technology? RAIN.RDY is Adidas's proprietary technical fabric system designed to block wind and rain while keeping the body dry inside. It channels moisture away from your skin, ensuring breathability during high-intensity trail riding. The membrane sits between the outer fabric and inner lining, and seams are sealed to prevent water sneaking through stitching holes.
