Synthetic insulation. Real performance.Ultralight Synthetic Sleeping Bags

If synthetic insulation is your choice, Sea to Summit offers fully featured synthetic sleeping bags with many of the same construction details as the down sleeping bags. They provide comfort, durability and thermal performance even in wetter conditions.

Sea to Summit’s synthetic lineup includes both unisex and Women’s specific bags, some featuring THERMOLITE® insulation, a high-quality fiber that achieves an excellent balance of lightweight warmth with superior compressibility.
It insulates when wet and dries much quicker than down, making our synthetic sleeping bags ideal for unpredictable weather or wet and damp adventures like kayaking trips and multi-season thru hikes.
Synthetic insulation retains warmth when wet and dries much quicker than down, making these sleeping bags ideal for unpredictable weather or wet and damp adventures like kayaking or hunting trips.

Our unique WaveLoft construction uses layers of insulation looped together into a ‘W’ cross-section to trap pockets of insulating air, providing our synthetic sleeping bags with superior warmth to weight ratios. In warmer weather, the Free-Flow Zip System on our more technical bags provides the greatest amount of ventilation available in a synthetic bag for multi-season versatility.
