The North Face Hyper Kazoo Sleeping Bag: 15 Degree Synthetic

Warmth like never before.

Slide into The North Face 15 Degree Hyper Kazoo Sleeping Bag for an exceptionally toasty night's sleep when facing frigid conditions in the mountains. Ready to handle three-season temps in the backcountry, the Hyper Kazoo uses water-resistant 800-fill ProDown insulation for reliable warmth in moisture-riddled environments, and then compresses small to keep the bulk down on the trail. This insulation's hydrophobic finish also improves your warmth by drying faster and repelling moisture ten times longer than your average untreated fill.

The North Face's innovative new ThermoBaffle construction traps heat in seamless baffles for unprecedented warmth and durability throughout without any dreaded cold pockets. Its shaped hood and down-insulated draft collar lock down your precious body heat when temps plummet. Pad loops give you a way to attach the sleeping bag to your sleeping pad to prevent you from slipping off the pad overnight.

Is this bag insulated the full length of the bottom or is a pad required to insulate the bottom?
Thanks

A 19 Degree Packable Bag

  • Familiarity: I've used it once or twice and have initial impressions

First of all just to clarify, this is a down bag, not synthetic. The EN rating is 19°F Limit / 30°F Comfort. I sleep slightly cold and need more cold weather testing to confirm, but I would say this EN rating is fairly accurate, the 15 degree rating mislead me a bit. The bag is fluffy and comfortable, yet packs down quite nicely. At 6'1" the Long bag fit well but didn't have as much room for anyone more than a few inches taller. It's a half zip which was more of an annoyance than a problem for me, but could be a deal breaker for some. The zipper is always a crucial point in sleeping bags and this one wasn't the worst I've used but certainly not the best - it took 2 hands to operate reliably. The hood of the bag stayed in place well and kept my head warm. The zipper pull is glow in the dark - who doesn't love glow in the dark!

My initial thoughts are that I'm happy with the bag but there are certainly some improvements that could be made. It will be my go-to spring/fall desert bikepacking/backpacking bag.

This is the nicest bag I've ever owned. It got damn near freezing last weekend and I crashed in my socks and undies. Which is to say: if I went to bed with layers on, I could sleep comfortably at substantially lower temps. And it packs down to the size of a large cantaloupe. How cool is that? (To this cheapskate, after a lifetime of bulky synthetic bags: really cool.)

I'm 5'11" and got the long bag--I figured it'd be nice to have room in the foot of the bag for my boots or water I don't want freezing solid. It works out great. I look forward to many brisk evenings wrapped snugly in this bag.
