Thermolite Reactor Compact Plus Liner

The Sea To Summit Reactor CompactPlus can increase sleeping bag performance by up to 11°C using dual-weight Thermolite® fabric. The regular 80g/m² material is combined with panels of 110g/m² Thermolite® fabric in the core body and foot box areas, adding additional warmth where it has the most benefit. The ergonomic mummy design also shaves off any excess weight, making this liner ideal for gram counters under 6 feet tall.
