400 Base UL is a warm down backpacking quilt for summer, autumn and spring.

A simple and convenient buckles fastening system allows you to adjust the internal space to fit your needs. The wide insulated collar wraps around the neck and prevents thermal loss from the inside.

You can open the bottom drawstring for ventilation, or unzip the zipper completely and turn the quilt into a blanket. It is comfortable to cover yourself on a warm summer night, in a car or in a hostel. Special loops make it possible to use the 400 Base UL as an underquilt for a hammock.

The insulation is Ukrainian goose down 870+ Fill Power. The down and fabric have water-repellent impregnation, which makes the quilt more resistant to wet off-season conditions.

1 review for ROCK FRONT 400 Base UL down quilt

  1. Kitty Mountain

    I have already tested it on two hikes and very pleased with it.
    Quilt design is really comfortable, it has a lot of space and warms better than a regular sleeping bag. Also, the fabric is very soft and pleasant. The only drawback is that you don’t want to get out of it in the morning)
