Cold, rainy weather and down insulation? Not just a dream with the Sierra Designs Zissou +15°F sleeping bag and the new DriDown™ finish for down insulation. It resists water and dries fast.

  • Features

    • Regular down takes on water and is very difficult to dry; through the DriDown proprietary process, each individual down plume is treated with a hydrophobic finish
    • With the down now resistant to water, the insulation maintains its loft and stays dry 7 times longer than untreated down
    • It also performs better in high humidity than regular down, and in case it accidentally gets wet, it will dry out faster, too
    • Lightweight yet durable 30-denier micro-ripstop polyester shell and comfortable, moisture-wicking polyester lining warms up fast
    • Baffle construction keeps down from migrating, eliminating cold spots
    • Full-length 2-way, double sliding zipper allows easy venting; locking slider is backed by wide, antisnag binding tape
    • Snag-free zipper tracks prevent the dreaded stuck zipper by creating a barrier between the lining and the zipper track
    • Fully insulated draft tube backing the zipper keeps body heat in and cold air out
    • Ergonomic, nonrestrictive hood cradles your head in warmth; hood features differentiated drawcords that make fit adjustments easy, even in the dark
    • Roomy, ergonomically shaped footbox enhances comfort and warmth of feet
    • Sierra Designs Zissou +15°F comes with stuff sack and storage bag
    • European Norm (EN) is an independent third-party temperature rating, allowing accurate comparisons across brands with other EN-rated bags
