What Our Gearhead(R) Experts Are Saying:"I used this on my Haven XL during a cold snap where temps dropped into the low 30s and never once felt that familiar chill creeping up from underneath. It also quieted down the usual crinkle of the air mattress, so I actually slept through the night."The XL Insulated Pad Cover is what turns a cold night in the XL hammock into a warm one. We've all felt that creeping chill that sneaks up through an air mattress right when we're finally getting comfortable, and this cover exists to shut that cold out before it ever reaches your back. Sized to match the extra room of the XL, it slides over your sleeping pad and adds a real boost of warmth right where it counts, while also softening the pad's feel and quieting the shifting and crinkling that usually comes with sleeping on air. Leave the heavier sleeping bag at home on milder nights, or keep it on hand for when the temperature drops. Once the night's over, fold it up, and it becomes a pillow, one less thing taking up space in the pack.
