The Chamber jacket is made from 100% woven nylon. The puffa has a polyester fill for warmth with a self fabric concealed hood. The puffa features a zip down the body front with snap buttons, with welt zip pockets on the front. The puffa also has a small badge near the front pocket. Its a regular fit, but I always encourage to purchase a size larger to allow for layering with a tee or perhaps a jumper/hoodie. The puffa filling does take up room around the body.
