Downright Dangerous

[This review was collected as part of a promotion.] The zipper cars on the too short zippers won't stay put, making the hood useless! If I did have a hooded down jacket with me I think I might have been hypothermic. I just returned it and will buy a bag with standard zipper layout. Additionally, the hood cinches won't stay put either and the little cords dangle ANNOYINGLY in your face.

Primo summer time adventure bag

I've used this sleeping bag for cool nights on a multiday raft trip down the Wild and Scenic Rogue River and several trailheads before big ski mountaineering objectives in the PNW. It's a great blend of lightweight and warmth needed for cool nights under the stars. I really like the expanding lower section for my bog feet (sz 15) and ability to store extra gear or clothing that might need to stay warm. The side zips work quite well to allow for easy extraction when needed. The length worked great for me at 6'5". Lots of compliments on the poppy stripes. This is an excellent compliment to my zero degree winter bag.

Men's Always Summer Sleeping bag

All my sleeping bags are made by Marmot, and they span the different seasons we have in Alaska. This bag is colorful and the new improvement is the fishtail you can unzip and move around in. Its down so its light but lofty. The zippers on my bags do not snag and the down stays in the bag and not falling out at the baffles. Just really well made and comfortable. If you buy a Marmot bag or two you will probabley never switch to another brand. My bags need to not fail me at 45 degrees and much more crucially at -20F, and I have never had any problems with Marmot bags. They are reasonable in price for such a good investment. No regrets ever with choosing Marmot. It may not be Always Summer in Alaska, but in this bright and citrusy bag you will want it to be.
