How to Buy Sleeping Bags
Get in: Sleeping bags are like shoes: They should fit. In the store, crawl in, stretch out, curl up, run the zipper, cinch the hood. A tight-fitting bag saves weight, but that won’t matter if you can’t sleep.
Check features: Do you like to sleep under the stars? Make sure the shell has a DWR treatment. Full-length zippers are better for venting but add weight. A snug-fitting hood adds critical warmth when it’s cold.
Choose your fill: Down typically packs smaller, but synthetics are best for extended wet (even compared to water-resistant down), and they’re catching up in warmth-to-weight ratio (see TNF Hypercat).
How to Buy Sleeping Pads
Check r-value: Sleeping pads use a numerical rating called R-value to measure insulation: the higher the warmer.
Go big: In general, choose the thickest, most cushioned pad you can justify carrying. Your back will thank you.
