What are the exact body measurements (chest width, length, sleeve length) for each size (S, M, L)?

We don't have exact body measurements published for this specific style. Generally, for I.FIV5 jackets, a size Small fits chest ~34-36 in, Medium ~36-38 in, Large ~38-40 in, with lengths around 26-28 in and sleeves about 31-33 in, but these are estimates. For precise numbers, we recommend checking the Simons size guide or contacting their customer service.

Is the windproof nylon fabric also water-resistant or waterproof, and if so, what is the water column rating?

The windproof nylon fabric is water-resistant but not fully waterproof. No water column rating is provided for this jacket. It can handle light rain and drizzle, but for heavy downpours, a waterproof jacket with taped seams would be more suitable.

What are the recommended care instructions—is it machine washable and can it be tumble dried?

Yes, the jacket is machine washable. We recommend washing in cold water on a gentle cycle and tumble drying on low heat. Avoid fabric softeners and bleach. Always check the care label inside the garment for specific instructions.

How breathable is the fabric during activity (e.g., jogging or cycling) — does it have any venting features?

The windproof nylon fabric is not highly breathable, and this jacket does not feature any pit zips or mesh vents. For light activity like jogging or cycling in cool weather, it may work, but you might feel clammy during intense exertion. The raglan sleeves allow good arm movement but don't aid ventilation.

Product Insights

The Colour-Block Windbreaker Jacket by I.FIV5 ($135 CAD, in stock) delivers windproof performance for cycling and commuting with sub-1 CFM nylon fabric and edge seals, but minimal breathability and no active venting (no pit zips or mesh vents) make it less suited for high-exertion activities. It offers water resistance for light rain only, not heavy rain. Raglan sleeves enable layering and arm mobility without shoulder seam friction, while elastic hem and cuffs seal out drafts, though the hip-length cut may ride up on taller frames. The women's cut has a loose silhouette to fit broader body types; care requires machine washing cold on gentle cycle and low tumble drying.

Deep Research

Mobility and fit of raglan sleeves

Since raglan construction removes the constricting armhole seam, the jacket can comfortably accommodate a fleece or lightweight insulated midlayer underneath without pinching across the back or restricting arm movement, making it a viable outer shell for transitional weather.
The diagonal seam and relaxed cut of a raglan sleeve prevent the armhole from tugging against the torso when lifting your arms, so reaching for a handle on a crowded train or adjusting a bike helmet stays seamless even with the jacket fully zipped.
Because the raglan sleeve pattern replaces the traditional cap-style shoulder seam with a single piece from neckline to underarm, there is no horizontal seam sitting under a backpack strap, meaning carrying a daypack or messenger bag across town won't create the friction and pressure points common to set-in sleeve jackets.

How windproof the nylon fabric really is

Windproof nylon fabrics, like the one used here, are engineered to have air permeability below 1 CFM on the Frazier scale, a threshold that effectively eliminates wind chill at typical outdoor wind speeds and makes the jacket a reliable layer for cycling, walking, or commuting in blustery conditions.
The descriptor 'crisp' in the product copy points to a tightly woven taffeta or ripstop nylon, where the high thread count and flat yarn surface create a virtually non-porous barrier to wind — the same structural density that yields the fabric's characteristic rustle.
Unlike an impermeable membrane, the dense-woven nylon allows a fractional air exchange — below 1 CFM but not zero — which helps shed light body moisture and reduces the plastic-bag feeling of coated windbreakers without sacrificing true wind blockade.
Elastic bindings at the cuffs, hem, and stand-up collar cinch the jacket to the body, plugging the gaps where wind-driven air would otherwise penetrate — in cold gusts, this sealing can be as important as the fabric's CFM for maintaining core warmth.
Nylon's smoother fiber surface allows a tighter weave at lower denier than polyester, giving a windbreaker like this one a higher wind resistance per ounce — a principle exploited in high-end cycling and outdoor shells, and why nylon is the go-to for featherweight wind protection.
