Introducing Peregrine Link-Up Field Quilts: a modular sleep system and multi-purpose quilt for minimalist backpackers, campers, and overlanders. This system specifically addresses the problem of “wandering” down quilts that slide off during the night. Our intuitive button system allows you to fasten the ultralight, packable Link-up down quilt to our soft, durable Link-up synthetic quilt (must match singles and doubles) to create an exceptionally warm and comfortable down-over-synthetic quilt combination.
