The Legion Packable is the perfect waterproof for dual sport and enduro style riding. The jacket packs into its own pocket meaning it'll stow away easily for those runs into the back country. The jacket is a 2.5 layer fully seam-sealed construction to keep the water at bay with a DWR treatment to provide protection from the elements.
With a 10k waterproof and 3k breathability rating it's the perfect jacket to keep warm and dry when the weather catches you off guard. Check in a tail back, backpack and know that it's got your back at all times. I personally love my waterproofing being an outer layer and the Legion Packable is fantastic at being small but useful.
The fitment is relaxed and should go over a jacket without issue. If you're wearing bulky armour and a riding jacket I would go up one size. If you only use a jacket your normal size should be fine.
I bought this jacket for trail riding, knowing that it would (hopefully) spend much of its time stored away in its integral stuff sack. Having just completed 450 of the TET in the UK I can vouch for this jacket. It is fully wind proof, waterproof and has enough ventilation. In addition to this the jacket folds down into its own pocket and has built in draw cords to cinch the jacket down into an even smaller parcel when it is packed away. This bottom line is I would recommend this jacket to others and I would buy it again. Well done Fox.
