For mild-weather pursuits, the Vesper provides essential warmth before packing to a tiny size.

For the lightest possible pack, Therm-a-Rest has crafted the Vesper 45F/7C to deliver the essential warmth needed for mild-weathered pursuits. To keep it light, we used powerful 900 fill Nikwax Hydrophobic Down certified by the Responsible Down Standard. Designed with high-quality materials and Therm-a-Rest performance features like SynergyLink™ connectors, a snap neck closure, perimeter side baffles and an insulated footbox provide warmth and comfort in the backcountry. When compared to sleeping bags, the Vesper quilts save weight and pack smaller by utilizing the warmth of your insulated pad.

• 900 fill Nikwax Hydrophobic Down™: Absorbs 90% less water and dries 3 times faster without using dangerous PFCs.
• Unrivaled Packability: Lightweight materials and precise design pack into a minimalist compression sack.
• SynergyLink^™ Connectors: Removeable ultralight straps create a secure bag-to-sleeping pad connection that optimizes the comfort and thermal efficiency of your entire sleep system. SynergyLink Connectors function best with regular sized sleeping pads that are 3 inches thick or less when inflated.

• Draft Protected: Perimeter side baffles and snap neck closure eliminate unwanted drafts.
• Responsible Down Standard Certified: Certification that ensures that the waterfowl in the down supply chain are treated humanely.
