- Fit: This is a UK Alpha M Regular jacket, so check the size and cut against your usual running layers.
- Packability: The front pouch pocket doubles as a stuff sack, so it is worth checking whether that format suits your storage preference.

Confirm the UK Alpha M Regular size, the Vibrant Orange colour and the packable smock format before choosing an offer. If waterproof rating, breathability and reflective detailing matter to your runs, compare those figures with the way you plan to use the jacket.
