Well, with a one-for-one record, I’m batting 1.000 (in American-speak), so why risk my immaculate record? But what the heck, I’m sure I can knock this one outta the park as well (another Americanism).
The fact is, you really don’t need much in the way of sleeping gear for that part of the world in August. You’d probably be just fine with a Cocoon Silk Mummy Liner from Design Salt (US$60; www.designsalt.com), which if you’re a warm sleeper ought to keep you comfortable to about 50 degrees Fahrenheit (ten degrees Celsius). You could increase that rating just by taking along a light blanket made with Polartec or similar material for an inexpensive but pretty warm setup.
Of course, taking a light sleeping bag provides that extra insurance just in case it does get a little cool at night. What you need is a synthetic-fill bag rated to around eight degrees Celsius. In the U.S., that list would include the Sierra Designs Delta Fastbag ($99; www.sierradesigns.com), which has an uninsulated nylon “floor.” Atop a mattress or pad, it’ll keep you warm to eight to ten degrees Celsius. I’m not sure if you can find one of those in Europe, but I know you can find a Lafuma Extreme 800, which should run about 60 euros (www.lafuma.fr). It’s an eight-degrees-rated, synthetic-fill bag that’s very light (one pound, 11 ounces, or 756 grams) and compressible. Mammut’s Kompakt Traveller (US$140聴119 euros; www.mammut.ch) is a similar bag with a synthetic fill and a temp rating of about eight degrees also. Stuffs down to nothing. You can always unzip and use it as a blanket, too.
Have a good trip!
