Key Features Explained
The combination of synthetic insulation and an air-permeable shell brings together insulation and breathability features. The shell is also described as wind- and water-resistant, but no waterproof rating is given, so do not treat this as a waterproof jacket.
The under-helmet hood and articulated sleeves are relevant design details for activities where a helmet may be worn or arm movement matters. They do not establish compatibility with every helmet or guarantee a particular range of movement.
What to Compare Before Buying
- Weather protection: Check whether a wind- and water-resistant shell is sufficient for your intended conditions, or whether you need a separate waterproof layer.
- Insulation: Compare the stated PrimaLoft Gold Active+ fill and its 60 gsm and 40 gsm specifications with the insulation level you are looking for.
- Weight: Use the listed 310 g figure when comparing jackets, while checking that competing figures refer to a comparable size and configuration.
Compatibility, Size and Fit
This listing is for size L in a regular fit. The description says the fit allows layering over baselayers and fleeces, but does not provide a size guide or measurements for the listed size. Check garment measurements and fit information before choosing a size. The under-helmet hood is a design feature, not confirmation that it fits a particular helmet.
Planning a Layering Setup
For a planned walk or climb, lay out the layers you expect to wear together and consider how the jacket’s regular fit works over your chosen baselayer or fleece. Think separately about insulation and rain protection: this jacket is described as water-resistant, not waterproof. Check the expected conditions and decide whether another outer layer is appropriate.
Before You Decide
Confirm that black, size L and the regular fit are right for you. Check the jacket’s water-resistance level against your needs, and consider the listed 310 g weight and PrimaLoft insulation when comparing alternatives.
