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.
- Windproof performance
Sub-1 CFM nylon fabric with edge seals blocks wind for cycling and commuting.
Why this is supported
The tightly woven nylon fabric achieves an air permeability below 1 CFM,
air permeability below 1 CFM on the Frazier scale, a threshold that effectively eliminates wind chill at typical outdoor wind speeds
How windproof the nylon fabric really is — cfm_under_1, and the crisp hand feel results from
tightly woven taffeta or ripstop nylon
How windproof the nylon fabric really is — crisp_hand_feel. Elastic bindings at the cuffs, hem, and collar
. Nylon's construction gives
higher wind resistance per ounce
How windproof the nylon fabric really is — nylon_vs_polyester_windproofness, keeping the jacket lightweight and suitable for cycling and commuting.
- Breathability
Minimal breathability: some moisture exchange but no active venting.
Why this is supported
The dense-woven nylon allows
a fractional air exchange — below 1 CFM but not zero — which helps shed light body moisture
How windproof the nylon fabric really is — permeable_yet_windproof, but
.
- Water resistance
Water-resistant for light rain, not waterproof for heavy rain.
Why this is supported
According to a Q&A, the windproof nylon is water-resistant for light rain and drizzle, but it is not fully waterproof; heavy downpours require a jacket with taped seams.
- Raglan sleeves
Raglan sleeves enable layering and full arm mobility without shoulder seam friction.
Why this is supported
The raglan sleeves
can comfortably accommodate a fleece or lightweight insulated midlayer underneath without pinching across the back or restricting arm movement
Mobility and fit of raglan sleeves — layering_ready_shoulder_fit. For overhead reach, the diagonal seam and relaxed cut
prevent the armhole from tugging against the torso when lifting your arms
Mobility and fit of raglan sleeves — unrestricted_overhead_reach. Additionally, the absence of a horizontal shoulder seam means
no horizontal seam sitting under a backpack strap
Mobility and fit of raglan sleeves — shoulder_seam_free_backpack_compatibility, eliminating friction points under straps.
- Ventilation
Jacket has no pit zips or mesh vents for high-exertion ventilation.
Why this is supported
While the raglan sleeves provide mobility, the jacket lacks dedicated ventilation:
don't aid ventilation
How breathable is the fabric during activity (e.g., jogging or cycling) — does it have any venting features?, and it has no pit zips or mesh vents for high-exertion activities.
- Fit guidance
Simons advises checking official size guide for accurate measurements.
Why this is supported
The brand recommends checking the official size guide for precise measurements:
For precise numbers, we recommend checking the Simons size guide or contacting their customer service.
What are the exact body measurements (chest width, length, sleeve length) for each size (S, M, L)?This applies to all their products.
- Construction fit
Raglan sleeves allow layering and arm mobility; elastic hem/cuffs seal out drafts but hip-length may ride up on taller frames.
Why this is supported
The jacket uses raglan sleeves, which eliminate shoulder seams.
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
Mobility and fit of raglan sleeves — layering_ready_shoulder_fitThe cuffs, hem, and collar are elasticized:
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
How windproof the nylon fabric really is — edge_sealed_microclimateThis provides a snug fit and draft protection, but the hip-length cut may cause the hem to ride up on taller wearers.
- Gender sizing
Women's cut; loose silhouette fits broader body types.
Why this is supported
The Colour-Block Windbreaker is cut for women (gender: female). The estimated chest measurements align with typical women's sizing, and the loose silhouette can accommodate a broader range of body types. According to the Q&A:
Generally, for I.FIV5 jackets, a size Small fits chest ~34-36 in, Medium ~36-38 in, Large ~38-40 in
What are the exact body measurements (chest width, length, sleeve length) for each size (S, M, L)?This indicates the jacket may fit beyond the typical women's size range due to its relaxed cut.
- Care
Care: machine wash cold gentle, tumble dry low, avoid bleach and softeners.
Why this is supported
The brand's customer service provides these care steps:
Yes, the jacket is machine washable. We recommend washing in cold water on a gentle cycle
What are the recommended care instructions—is it machine washable and can it be tumble dried?, and that it can be dried on low:
