What to Compare Before Buying

  • Size: This is size L, so compare it with the fit you usually need and any layering you plan to wear underneath.
  • Weather protection: The jacket has a 2,000 mm waterproof rating and taped seams, so check whether that level matches the conditions you expect to face.
  • Breathability: The stated 2,000 g breathability rating is relevant if you want help managing perspiration while wearing the jacket.
  • 3-in-1 use: The outer shell, inner jacket and combined wear option give three ways to wear it, so confirm that this format suits how you want to use the jacket.
  • Closure and storage: Adjustable cuffs, a detachable hood and zipped pockets are the details to compare if those features matter to your day-to-day use.

When to Consider a Different Option

Consider a different jacket if you need a size other than L, a different colour or a higher waterproof rating for your intended conditions. The 3-in-1 format also makes this a poor fit if you only want a single-layer shell or a separate lightweight jacket.

Before You Decide

Check the size, colour and 3-in-1 construction before choosing an offer. It is also worth confirming that the 2,000 mm waterproof rating, 2,000 g breathability rating and detachable hood suit the way you plan to wear it.

Checking the Fit

Before choosing a size, check the relevant size guide and consider what you expect to wear underneath the jacket. Compare chest, shoulder and sleeve measurements with a jacket that fits you well, and allow for comfortable movement with your planned layers.
