Brooks-RangeDrift 45 Sleeping Bag: 45 Degree Down

Drift to sleep.

The Brooks-Range Drift 45 Sleeping Bag is an ultralight and compact choice for backpacking at high elevations in the warmer months of the year. Its 850-fill down insulation has the highest warmth-to-weight ratio available in the Brooks-Range collection, so it'll stay surprisingly warm for how little it weighs. Brooks-Range treated the insulation with DownTek to retain its lofty warmth when you're exploring damp, wet, and moist environments.

Brooks-Range treated the Drift's shell with DWR to shed moisture, light rain, and watery spills to keep you comfortably dry all night. The bag uses Brooks-Range's unique Flow Construction, which baffles the insulation vertically to reduce shifting and prevent cold spots over time. An internal storage pocket stows electronics that you don't want to get zapped by the cold during the night.

What are the dimensions of the storage sack, i.e. how small is the bag when packed?

Hey there Chandra!

That bag should be around 7.5-17 inches I think! That is a measurement they don’t offer anywhere at all so compared to other bags with similar specs that should be a similar size! You should get Sea To Summit eVent Compression Dry Sack in a size small or a Outdoor Research UltraLight Compression Sack in the 8L you can call me at 801.204.4660 for a discount on full priced items, free returns or gear advice! if you prefer you can send me an email as well!
