Onyx 30 Series Sleeping Bag - Castlerock

The 300T polyester shell handled a damp, windy night without letting any chill through, and I was surprised how small it compressed into my pack. It's light enough that I forgot it was even in there, but the fabric feels sturdy, not flimsy.

Went up to 11,000 feet in Castlerock last weekend and the chill never got to me — the 300T polyester does exactly what it's supposed to. It's light enough that I didn't regret stuffing it in my pack, and it squished down into my bag's bottom pocket without a fight.

The polyester shell feels durable yet soft, and I was surprised how easily it compressed into my pack for an overnight trip. Stayed perfectly warm despite a brisk mountain breeze.
