What to Compare Before Buying
- Size: This variant is size 14. Check the fit you need before choosing a jacket.
- Layering: The 3-in-1 format gives you an outer shell, an inner jacket, or both together. Compare that with how you want to wear it.
- Weather protection: The jacket is stated as waterproof to 10,000 mm with taped seams. Compare that with the level of wet-weather protection you want.
- Breathability: The stated 5,000 g rating matters if you want a jacket that lets perspiration pass out of the garment.
- Fit adjustment: Adjustable cuffs and an adjustable hood are listed, so check whether those features matter for your preferred fit.
Before You Decide
Confirm that size 14 is the right fit and that you want a khaki 3-in-1 long jacket rather than a single-layer coat. If waterproofing, breathability and the detachable inner jacket matter to your choice, check those details against how you plan to wear it. The stated thermal test rating and warranty are also worth noting before you choose an offer.
