Tracker +5°F Mummy Sleeping Bag

The Lowepro Wynit 1037 is a mummy-style sleeping bag rated to +5°F for solo adult use in hiking and backpacking. It uses PolarLite insulation with body mapping that places extra fill in the vaulted foot-box to keep feet warm. A three-piece hood cinches tightly around the face and a full-length zipper draft tube seals in heat.

Temperature Rating and Weight Limits

The +5°F rating sets the practical lower bound for comfortable sleep; colder conditions will require additional layers or a higher-rated bag. At 2.1487 kilograms the bag is light enough for backpacking yet the single-person cut and mummy taper restrict movement for larger users or those who prefer a rectangular shape.

Medium Size with 87-Inch Length

The Medium regular measures 87 inches long by 34 inches wide at the shoulders, fitting most adults up to that height. Buyers taller than 87 inches or who need a wider cut will find the bag too short or narrow, and no longer or wider version of this model is offered.

Questions about this item

Which temperature rating should I choose between the +5°F Tracker and the other models listed?

The Tracker +5°F is the coldest-rated single bag shown; the Journey is rated +40°F and the Trailhead +20°F, so pick the Tracker for sub-freezing trips and the warmer models for milder conditions.

What does the +5°F / -15°C rating mean when I am actually sleeping in the bag?

The rating indicates the lower limit at which the bag can keep an average adult warm; the vaulted foot-box with extra fill and the three-piece hood are designed to maintain comfort down to that temperature when used with a sleeping pad.

How does the compression sack affect packed size and weight?

The included Oxford compression sack with drawstring and barrel-lock lets you stuff the 4.1-pound bag into a compact bundle for backpack carry without rolling.
