Mountain Hardwear Hyperlamina Spark Sleeping Bag: 35 Degree Synthetic


Product Details

Lighten up your pack with the Mountain Hardwear Hyperlamina Spark 35 Degree Synthetic Sleeping Bag. This lightweight bag is ideal for climbing trips in the summer as well as backpackers looking to save some trail weight. Utilizing a welded construction, the bag boasts a better warmth to weight ratio than traditional synthetic fill bags since there are no cold-inducing stitches. Combined with a zoned insulation, which places additional insulation at your core and feet, you get more warmth where you need it, without any unnecessary weight. The center, half-length zipper saves weight, while maintaining the ability to vent the bag if you start to get too warm. The snug-fitting performance mummy cut is designed to maximize warmth while eliminating needless bulk and weight. When the night starts to get cold, fasten the face gasket and cinch down the tailored hood to stay warm, so you're ready to get after it once the sun comes up.

Lightweight Sleeping Bags Checklist

Sure It's Warm Enough? Lightweight bags are meant for use in weather between 30-50 degrees. But, remember, it's always prudent to add on at least 10 degrees to the bags rating. Thus, a bag rated to 40 degrees might only keep you warm in 50 degree weather.
Down or Synthetic? Each have their advantages. Down is less bulky and weighs a few ounces less. Synthetic costs less (usually) and is easier to dry - you can just toss it in the dryer.
Don't Forget the Sleeping Pad! A sleeping bag is useless without a sleeping pad. So, if you don't already have a sleeping pad, get one. For lightweight sleeping bags (thus used in warm weather), you don't need a super thick or winter-style one.
Ideal Uses for a Lightweight Bag. Where you know...for sure...that the temperature will stay at least 10-15 degrees above the sleeping bags rating. And, where every ounce and cubic inch of space is at a premium. Lightweight bags are often used by climbers and bike campers/travelers. For backpacking in the mountains, a lightweight bag is NOT recommended!
