Using 403g of minimum 700-fill power DOWN CODEX-approved duck down and a high-performance, 100% recycled Helium 20D outer fabric, the Helium 400 is warm, lightweight and ultra-compressible for easy packing. Efficiently sized, supremely comfortable and very low in weight for backpacking and cycle touring while still being warm enough to cope with chilly nights.

Slant-baffle construction through the body maximises warmth, improves packability, and prevents down migration, keeping you warm night after night and preventing cold spots. At the foot of the bag, a four-baffle system focuses essential warmth around your feet, while in the hood, a five-baffle system optimises comfort and keeps the down precisely where it needs to be.

Inside the bag, a 100% recycled Supersoft 20D lining fabric with PFAS-free DWR offers breathability and durability for comfortable nights and a long lifespan, while a full-length Gemini™ entry zip baffle practically eliminates heat loss in this vulnerable area and is stiffened so it won’t catch in the zip. The low-profile magnetic Lode Lock™ closure and collar drawcords are practical and easy to use in the dark.

Designed with a technical yet comfortable Alpine 2.0 fit, Helium bags optimise thermal performance while minimising weight. With a Good Night’s Sleep Temperature of -5°C (23°F), the Helium 400 offers reliable warmth for travel to more northerly latitudes and for early spring and autumn use at higher altitudes.

My new favorite summer sandal!
Size: 8.5, Color: Bay Fog
I am loving these shoes so far this summer! The color is so cute, perfect for a light summer palette. It's the perfect light purple that doesn't make me look pale or washed out. For reference, I have fair to light neutral skin tone. They are SO comfortable - a little too comfortable for a shoe, it's more comfortable than my ugg slippers! They do take a second to put on as you have to either force your ankle in without unstrapping the back - don't judge me - or undo them. Thankfully they have a strap to help get them on easily. I love these shoes. I am a medium width, but I think these have some wiggle room since both the straps are velcro and adjustable somewhat. They are easy to walk in, hold onto the foot, have been more balanced than some others I have had in this platform style, and are very cushioned to walk in. Slight arch support to me but I have somewhat high arches so if you are more flat footed or standard arch these will give you even better support. Really impressed with these. They are more casual but work with many different outfits from sundresses to jeans. For me, these were a great buy and I will be wearing them all summer.

Style, Comfort
Size: 9, Color: Sand
If I could give a Ten Star review, I would. Hands down the most comfortable pair of sandals I have ever owned. I wore them 16 days straight while touring Italy. Comfortable and goes with all of your outfits. They pack well in a suitcase too. Light weight.

Wonderful
Super comfy and easy on and off, yet stylish imo! I could walk miles in these as a 56 yo and have worn them for three years! I hope they never stop making them. The only tweek I would suggest is to cover the footbed with leather or suede not cloth so they would last longer!
