What to Compare Before Buying

  • Size: This is size 12, so compare it with the fit you need for layering and comfort.
  • Weather protection: The jacket is stated as 10,000 mm waterproof with taped seams, so compare that level with the conditions you expect.
  • Breathability: The stated 5,000 g breathability gives a figure to check if you expect more active wear.
  • Wear options: It is a 3-in-1 design, so decide whether you want the shell, the inner jacket, or both together.
  • Fit adjustment: Adjustable cuffs and hood help you check whether the jacket’s adjustment features suit your preference.

When to Consider a Different Option

Choose a different jacket if you need a different size, a shorter or longer fit, or a jacket without the 3-in-1 layout. Buyers who want a different balance of weather protection and breathability should compare those stated figures before deciding.

Before You Decide

Confirm the size 12 fit, the Dark Green colour and the 3-in-1 construction before choosing an offer. If the weather rating, breathability figure or thermal test matters to your decision, compare those stated values with your intended use.
