Sleep Systems August 20, 2008
Presented by: Mike C I. Sleeping Bags A. Two Types 1. Down bags 2. Synthetic bags B. Down bags 1. Higher warmth to weight ratio 2. Smaller pack size 3. Longer lasting 4. Not warm when wet! 5. Generally more expensive than comparable temperature synthetic bag 6. Fill power = 1 oz of down takes up x-number of cubic inches of volume… Example: 800 Fill Down sleeping bag uses an 800 fill quality down meaning it is more lofty and physically lighter weight than a 600 fill bag of the same temperature rating. C. Synthetic bags 1. Available in different insulations… Example: Primaloft, Polarguard, Climashield, Thinsulate etc… 2. Generally less expensive than comparable temperature sleeping bags 3. Better for wet conditions because it insulates when wet! 4. Extreme cold temperature sleeping bags with synthetic insulation are generally quite bulky and heavy compared to down 5. Easier to maintain than down bags, but not as long lasting D. Caring for Sleeping Bags 1. You can clean your down bag yourself! a. Use a special cleaner made for down such as Down Wash made by Nikwax. b. DO NOT DRY CLEAN!!! c. Down has natural oils that allow the down to stay lofted, traditional detergents (and dry-cleaning) will strip these oils and possibly damage the filling! d. If possible, use a front-loading washer, as these tend to be gentler for fabrics, especially for the sewn baffles of the sleeping bag. If you can’t find a front-loading washer, wash it by hand! e. Handle the wet sleeping bag with care. Do not “wring” it out, instead, “push” the excess water out. Try to keep the bag supported as to not put extra stress on the baffle stitches. f. Dry the sleeping bag in the dryer using a low heat and throw in some clean tennis balls to aid in the re-lofting process 2. Cleaning synthetic bags a. Use a mild soap and follow the same guidelines as a down bag. b. A great soap to use would be Tech Wash, made by NikWax because it rinses clean and doesn’t leave residues on fabrics! II. Sleeping Pads A. Why use a sleeping pad? 1. Every sleeping bag acquires it’s temperature rating using a 1 inch sleeping pad. 2. You will sleep warmer and prevent head loss between you and the ground. R-Value is the rating of a material’s resistance to heat flow. Most pads include an R-Value to give the consumer an idea of how warm the pad is compared to others. B. Foam Pads 1. Can’t puncture 2. Not as comfortable as inflatable pads 3. More durable 4. Have a lower R-Value than an inflatable pad C. Inflatable Pads 1. Have a higher R-Value than foam pads 2. Thicker and more comfortable than foam pads 3. Less durable with the risk of puncturing the pad (repair kits are available) III. Tents A. Choosing a tent that’s right for you. 1. How many people do you want to sleep in it? 2. What kind of use do you want out of it? (3-season vs. winter camping) 3. What is your budget? 4. How important is weight and pack size? 5. What features are important to you? (2 doors, large vestibule space, internal pockets, lots of mesh for ventilation, etc…) B. Double wall vs. Single wall tents 1. Double wall a. Have a dedicated tent body and a separate rain fly b. Usually have a good bit of mesh for ventilation c. Good for most conditions d. Not as light as Single wall tents 2. Single wall a. There is no separate rain fly, the tent body is usually waterproof in nature b. Lighter weight than double walled tents c. Minimal ventilation d. Condensation is usually an issue in humid environments C. Types of tents 1. Backpacking tents a. Generally around 5 lbs for a 2-person tent b. These have light weight poles and tent fabrics c. Use a lot of mesh fabric in tent body to save weight (and add ventilation! 2. Ultra Light a. Tarps b. Hammocks c. Fly only pitching with tent footprint d. Bivy sacks are ultra light shelters 3. Car camping tents a. Made of tougher, heavier fabrics b. More spacious and greater interior height c. Have more features such as zippered windows and internal pockets. d. Economical choice 4. Mountaineering tents a. Built to survive extreme winds and snow loads b. Usually single walled c. Used on expeditions D. Tips for tents 1. Be familiar with your tent and set it up before your first trip 2. Don’t store your tent when it’s wet! a. Mildew will form and degrade the tent fabrics b. Allow the tent to dry completely before long-term storage 3. Protect your tent from the sun! a. UV rays are harmful to fabrics (polyester is more resistant than nylon) b. Try to set up your tent out of direct sunlight c. UV degradation happens slowly so don’t worry too much but be aware of it d. Treat the tent fabrics with NikWax UV Proof. It’s like sunscreen and waterproofing in one application for your tent!
