The Marmot Cirque Featherless Jacket keeps the fun times rolling throughout the cold of winter. Its 3M Thinsulate Recycled Featherless Insulation imitates the warmth of down by using primarily loose fibers to trap in air, and therefore heat. The Cirque is constructed with ripstop fabric which stands up to the abrasive nature of the playground, and has a DWR treatment to help moisture bead up and roll off instead of seeping in. The synthetic insulation won't collapse even if it does get damp, so it continues maintaining warmth throughout flurries and showers. The shoulders feature Angel-Wing Movement technology to ensure freedom of motion and the sleeves end in elastic cuffs to keep them in place in any position.
