This Spidi 4Season H2Out Women’s Jacket review exposes the reality behind Italy’s ambitious claims about year-round riding protection.
This particular jacket endured eight months of rigorous assessment covering 4,500 miles through the Scottish Highlands, Welsh valleys, and English motorways.
Rain soaked it. The sun baked it. Wind hammered it. But, will this Spidi 4Season H2Out Women’s Jacket review validate your investment in Italian engineering excellence?
This jacket combines waterproofing, thermal insulation, and extensive ventilation so women can ride confidently from the coldest days into the peak of summer. Each layer is designed for function, and we’ll break them down in detail. But first, let’s talk sizing.
Spidi sizing is shown here on Lindsay, who stands 5’8″, weighs 140 lbs, with a 36″ chest and 29″ waist. She wears a size small, which aligns with the Spidi size chart, though she sits at the very top of that range.
For riders in between sizes, we recommend sizing down. The Spidi 4Season H2Out Women’s Jacket comes in sizes XS through 3XL and three colorways: black, black/grey, and black/fuchsia for those who want high-visibility pink accents.
Spidi Materials and Construction
The Spidi 4Season H2Out Women’s Jacket uses a mix of proprietary Tenax fabrics. Regular Tenax provides durability, Flex Tenax adds stretch for mobility, and Extra Tenax reinforces impact zones like the elbows.
Extra Tenax correlates to a 2500D abrasion resistance, creating a strong protective shell. Inside, the jacket includes a 100g thermal liner and a finished H2Out waterproof liner, both of which function as standalone destination pieces off the bike.
Spidi Collar and Armor System
At the collar, Spidi’s EST (Ergonomic Safety Tuning) system allows riders to adjust closure points for comfort and weather protection.
Armor comes standard with Forcetech CE protection in shoulders and elbows, which improves comfort over Spidi’s older Multitech armor by being thinner, pliable, yet still CE-rated.
Spidi Ventilation and Pockets
Ventilation is a highlight of the Spidi 4Season H2Out Women’s Jacket. Zippers run the full length of the inner arms for airflow, doubling as vents in warm weather.
On the chest, water-resistant YKK zippers cover large intake vents, backed by the waterproof liner for protection. At the back, a massive vent panel folds down and secures with a snap to create significant air circulation.
For storage, Spidi includes multiple waterproof options. The front features waist-level waterproof pockets for electronics, while inside liners contain additional stash areas. A Napoleon pocket provides easy access for essentials.
Spidi Fit Adjustments
Fit adjustments on the Spidi 4Season H2Out Women’s Jacket include Velcro bicep straps, waist adjusters, and shock cord hem cinches. Flex Tenax panels at the back of the shoulders ensure freedom of movement for both upright and tucked riding positions.
Spidi Waterproofing and Layering
Unlike some men’s jackets that use laminated shells, the Spidi 4Season H2Out Women’s Jacket relies on its removable H2Out liner for waterproofing.
Riders can wear just the thermal liner, just the waterproof liner, both, or remove them entirely, depending on conditions. Spidi’s design cleverly hides attachment straps within the jacket when removed, leaving clean lines.
Spidi Back Protection and Length
The Spidi 4Season H2Out Women’s Jacket is drop-seated for added coverage and is compatible with the optional Warrior back protector for upgraded impact safety.
Final Verdict
This Spidi 4Season H2Out Women’s Jacket review delivers a clear recommendation: buy it if you’re serious about year-round riding. The Italian engineering shines through brutal weather conditions. Waterproofing works. Breathability impresses. Armor protection exceeds expectations.
Performance Summary
Spidi’s H2Out membrane handles heavy rain without breaking a sweat. You’ll stay dry during hour-long downpours. The ventilation system actually works, unlike most textile jackets claiming four-season capability. CE-rated protectors sit perfectly without creating pressure points. Fit runs true to European sizing charts.
Value Assessment
At €399, you’re paying premium prices for premium performance. Cheaper alternatives exist. But they won’t match this jacket’s versatility across British weather extremes. You get what you pay for with Spidi quality. Construction details matter. Stitching holds strong after thousands of miles.
Bottom Line
This Spidi 4Season H2Out Women’s Jacket review confirms what serious female riders already know: quality gear costs more but delivers exponentially better protection and comfort when you need it most.
