Oh, the nervy, insouciant way with which some people mention things. 聯Yes, I聮m going sea kayaking in Palau,” or, 聯Oh, I聮ll be at my villa in Tuscany for the rest of the month,” or 聯Please don聮t call me for a week, as I聮ll be skiing through the Alps and will simply refuse to answer the phone.”
Cocoon Ripstop Silk Mummy Liner

While the rest of us sit and work, giving advice so that other people can enjoy their splendiferous vacations just a pinch more.
Bah.
But I digress. If I were flying to Palau to go sea kayaking聴did I mention I聮m not doing that, although I聮m not at all bitter about it聴I聮d take two things. One would be a silk sleep-sack, just a very light piece for nights when it聮s too warm for anything else but you聮d like a little something to tuck yourself into. The Cocoon Ripstop Silk Mummy Liner ($65; www.rei.com) is just the deal. Use it as a superlight sleeping bag, or add it to any bag for more warmth. It also helps keep a sleeping bag clean.
For a bag, I like the Marmot Pounder ($159; www.marmot.com). As advertised, it weighs one pound, and has a 40-degree temperature rating. The insulation, such as it is, is Primaloft, which I like for its softness and water-resistance. With the silk liner, that combo actually would keep you snug into the low 30s, as if that were a worry in this case. Or, there聮s REI聮s Travel Down +45 bag ($75; www.rei.com), a down-filled warm-weather bag that in turn can be used for a bag liner when you聮re back in a cold climate.
Anyway, happy kayaking. Grrr.
