The Basecamp BT3 has been designed for those of us who find a mummy bag restrictive, and who would prefer to enjoy a little more comfort and stretch out space while escaping outdoors.

The Basecamp BT3 offers a contoured rectangular design to accommodate sleepers who like to stretch out full length, or those who like to curl up into a ball. It is also a fantastic solution for restless sleepers who can now move freely within their bag.

If you are looking for the ultimate in camping comfort, the Basecamp BT3 has also been designed to work with all our sleeping mats and Aeros Pillows to create a truly comprehensive sleep system. Slide your mat into the small pocket at the foot of the bag and then use the strap and loop set-up to secure the upper section. Then inflate your Aeros Pillow to the perfect pressure before securing it into place with the elasticised strap underneath the hood.

No matter which way the weather turns, the Basecamp BT3 bag can be modified to suit. Zip yourself in and pull the internal drawcords tight to combat the cold. If the weather takes a turn towards summer, then you can vent the feet, or unzip one or both sides to keep yourself cool and comfortable. The Basecamp BT3 is so much more than just a sleeping bag; the dual zipper allows it to transform from a substantial and sumptuous bag into a svelte summer quilt. The bottom of the quilt holds its shape as a roomy footbox, and a series of attachment loops even lets you secure your quilt onto your mat to ensure maximum warmth.
