VECTOR or ARC?

This article describes the two different foot end designs we offer. All other features and custom options of the two types are similar. Neck closure, strap configuration, fabric choices, all the same.

The Arc foot is permanently sewn closed, the Vector is adjustable from closed to open blanket style with a few simple steps.

We feel the thermal efficiency of the closed foot end Arc is superior.

Nunatak makes Quilts with two distinctly different foot designs.

On the left, the Vector with the openable, blanket style foot end.

The Arc, with its permanently closed footbox is on the right.



Footbox Option 1: Mummy Style Closed Footbox

The traditional closed footbox on our Arc Quilts will be familiar to mummy bag users. It is the simplest and most thermally efficient quilt design. No cords to fumble with, zippers to break or noisy velcro. And if the lightest possible gear is your thing, this is it.

A view that should be familiar to users of mummy bags: enclosed and snug, this option gives you the most warmth for the lightest package.

Footbox option 2: Vector Adjustable Footbox

The broad adaptability of quilts, from cold weather tucked-in comfort to warm summer nights, is further realized by the adjustable footbox of the Vector. With very little effort the quilt completely unfolds from an enclosed foot area to a true blanket style cover. Several levels of ventilation in between are possible with the transverse drawcord closure, plus snap supported velcro.

The center release buckle is securing the cord closure so the Velcro does not open up when the drawcord is pulled tight.

The drawcord channel is positioned across the quilt in a way that creates a puffy, well insulated 'collar' when closed...

..which happened here. Nice and tight, virtually draft free. 

The opening left after cinching the cord tight will get really small, to the point where forcing a finger through takes some effort. Yet, on the coldest nights, or windy conditions under a tarp with no bivy, some cold intrusion still takes place.

A small, down filled 'dog bone' is supplied along with Vector foot style quilts to cinch in place for a tight seal...
