Puk -2° Curve is the ideal 3 Season bag. The new Curve shape by Nordisk provides extra space without compromising comfort or warmth. The shell is lightweight and durable rip-stop, and the lining has a soft touch. The Norguard S-PO 80 filling offers great insulation when cold, and when it gets too warm, the full-length zipper with jam-guard allows the bag to fully open. Personal items are kept safe in the internal chest pocket. A contoured hood and the internal thermal collar makes the bag versatile for use at the start and end of the season.
