Key Features Explained
The separate shell and inner jacket allow three ways to wear the garment. The listing describes wearing both together for warmth, but does not specify the inner jacket’s insulation or a temperature range for each configuration.
The 5,000 mm waterproof figure is paired with a moderate-rain suitability claim. Taped seams are intended to limit water passing through stitched seams. The detachable hood and adjustable cuffs offer ways to alter the garment’s arrangement; check the fit and fastening details that matter to you.
What to Compare Before Buying
- Fit: This listing is for size 12. Check the size guidance and consider how the jacket fits over the layers you expect to wear beneath it.
- Rain protection: Compare the 5,000 mm rating and moderate-rain description with the conditions you need to dress for. The listing does not give a separate rating for the hood or other openings.
- Breathability: The stated figure is 5,000g, without a time unit. Avoid comparing it as a like-for-like rating unless the other garment’s rating uses the same measurement basis.
- Thermal claim: The -30°C figure is a laboratory test claim, with performance affected by activity and perspiration. Do not treat it as a personal comfort guarantee.
Choosing the Correct Version
This page describes the black, size 12 version. Check the selected size and colour, as well as the exact 3-in-1 configuration, when reviewing a product option. The listed item quantity is one.
Plan Your Layers Before a Walk
Before heading out, think through which of the three wearing options you may use and try the jacket with the layers you expect to wear underneath. Check that the size allows the fit you want and that the detachable hood and adjustable cuffs sit as intended. These checks can help you decide whether the configuration suits your plans; they do not change the jacket’s stated test ratings or guarantee comfort in particular weather.
Before You Decide
Confirm that size 12 and black are the intended variant. Consider whether the three-way arrangement, 5,000 mm waterproof rating and stated thermal test claim match your requirements, and bear in mind that the breathability figure is given without a time unit.
