What is TILT Technology?
A radical, heat retaining tech that works like an emergency blanket reflecting heat back towards your body, while maintaining breathability and comfort. Boosting thermal efficiency, it keeps you warm when the temperature plummets.
Rab's TILT fabric (Thermo Ionic Lining Technology), is used in the inner lining of their top-of-the-line sleeping bags, sleeping mats and down jackets. This technology reflects heat back toward the body, reducing radiative heat loss and increasing warmth. It significantly improves the warmth-to-weight ratio without altering the fabric's original properties or adding weight. At Ultralight Outdoor Gear, we prioritize this balance - enhancing the insulating capabilities of gear without increasing its weight. Improvements like these earn our enthusiastic endorsement.
