Sleep System Reviews

Sleep System Buying Guide

Your sleep system is one of the "big three" weight items. Here's how to choose the right combination of bag/quilt and pad.

Sleeping Bags vs. Quilts

• Sleeping Bags: More foolproof, warmer for cold sleepers, better for tossers and turners. Heavier.
• Quilts: Lighter (no insulation underneath you anyway), more versatile, better ventilation. Requires learning to use effectively.

Down vs. Synthetic

• Down: Best warmth-to-weight ratio, packs smaller, lasts longer. Loses insulation when wet (though hydrophobic down helps).
• Synthetic: Retains warmth when wet, less expensive, dries faster. Heavier and bulkier for same warmth.

Temperature Rating

Most ratings are "survival" ratings, not "comfort" ratings. Cold sleepers should add 10-15 degrees to the rating. EN/ISO tested ratings are more reliable than unrated products.

Sleeping Pad R-Value

• R-value 1-2: Summer only
• R-value 3-4: Three-season use
• R-value 5+: Winter and cold sleepers

Your pad R-value matters as much as your bag rating. Cold from below is a common complaint.
