For the alpinist looking for a lightweight, low bulk bag suitable for cold temperatures, the Neutrino 400 offers exceptional packability and warmth for its weight. Designed with a narrow mummy fit, for reduced bulk and pack size, and constructed with lightweight, high performance materials. It’s perfect for three season mountain missions. The Neutrino 400 is filled with 400g of 800FP, goose down, stabilized in chevron shaped baffles, cleverly designed to reduce the amount of fabric needed compared to traditional horizontal baffles. The trapezoid boxwall baffle construction allows the down to fully loft, eliminates cold spots, and maximizes warmth. Additional baffles along the length of the zip and around the neck decrease heat loss, and with an adjustable drawcord around the hood you can cinch the bag around your face. Now built with a recycled nylon lining and recycled Pertex® Quantum outer, it’s wind resistant and a little lighter on the planet too. The down is also finished with a Nikwax, fluorocarbon-free hydrophobic treatment for coping with condensation.

So comfy
Size: King (Pack of 1), Style: Standard Loft (4" - 5")
I spent time looking up/watching videos on pillows for neck pain and this one comes up a lot. I’m someone that used to wake up every few weeks with a stiff neck so bad it could make me cry at work. I haven’t had that happen once after months of using this pillow. I look forward to laying my head down on it every night. It’s a luxury experience every time. I think what it does so well is maintain its shape. You can really squish it up how you want and it stays there even after hours. Moldable but somehow still firm. It’s expensive but to me the value is there because I no longer get crazy neck pain from sleep. Worth trying it out for sure. Btw I was stuck between this is and Purple brands couple top end options. I never got around to trying them because I tried this one first and was very satisfied! Feb 2026. Still use it every night and it's still protecting me from neck pain I used to get from sleeping. It's held up amazing. Hope to use it for many more years.

Saatva Pillow is great
Size: Standard/Queen (Pack of 1), Style: Standard Loft (4" - 5")
So far this is the best pillow I have had in the last 10 years and I have tried two Purple pillows a couple different memory foam and Gel pillows at least 4 more pillows that I can't even remember the names of. My neck and shoulders are almost pain free. I have also been doing more stretching of my arms which is also helping, but this pillow has really made the most difference in the pain I have had, I felt difference from the first time I put my head on it. It's comfortable, the perfect height I got the 4"-5", I also got the queen size and it's great. It supports my head just right. I also ordered the Saatva Classic 14" mattress from the company and I sure hope it's as good or better would be great because I have back issues for the last 50 years.
