Exponent Atom X380
Reliable, durable and compact, the Atom X380 has all the right credentials for a lightweight summer sleeping bag thanks to a combination of compactable, efficient insulation and a hardwearing construction with high-endurance yet comfortable materials.
The nylon ripstop shell is designed for an active adventurer, coping with variety of terrains thanks to a strong ripstop weave that stops a rip in its tracks before it ruins a good night’s sleep. High performance Coletherm® Micro insulation is a bonded micro-fibre insulation, there is no fibre migration and so, no cold spots.

Atom Range Features:
- Ripstop nylon is lightweight but strong and resistent to tears. Extra-strong weft and warp threads are woven in every 5 mm. Should the fabric tear, the tear is stopped at these strengthening thread points (ripstop).
- The nylon shell and lining is soft to the touch for comfort, has a fast drying time if it becomes damp and is lightweight.
- Coletherm Micro insulation is a bonded micro fibre that offers great heat to weight ratio, as it is bonded there is reduced fibre migration and as a result, no cold spots.
- The loose construction minimises cold spots across the sleeping bag.
- 3D foot area provides space for extra comfort as your feet are in a natural resting position, it also reduces the compression of insulation, allowing it to perform at the correct level.
- The auto-lock zipper keeps the zipper locked in place and does not accidentally open while you are sleeping, ensuring that it only moves when you want it to.
- The thermo collar minimises heat loss across the shoulder area, an additional baffle of insulation ensures that warmth is kept in the sleeping bag.
- The Thermlock zipper baffle runs down the full length of the zipper reducing heat loss in this vulnerable area.
- You can keep your valuables close with the internal security pocket.
- Adjustable hood with “push and release” toggle to retain required position.
- 4-way compression stuff sack for maximum compactness.

This high performance synthetic insulation is very light and compressible,
resulting in extremely compact pack sizes.
It is a bonded micro fibre insulation that works by trapping air around
the fibre for a more effective performance.
It offers a great heat to weight ratio and as it is a bonded insulation
it has reduced fibre migration, eliminating cold spots.
