With a more generous fit than the standard Helium range, the Helium GT series are designed for extended use and are exceptionally comfortable for those who like a little more room to move. Using 449g of minimum 700-fill power DOWN CODEX-approved duck down and a high-performance, 100% recycled Helium 20D outer fabric, the Helium GT 400 is efficiently sized, supremely comfortable and 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 more generous GT Fit, the Helium GT follows the same tapered shape as the Alpine fit but with a broader profile that doesn’t sacrifice performance. With a Good Night’s Sleep Temperature of -5°C (23°F), the Helium GT 400 offers reliable warmth for extended backpacking and travelling through the spring and summer months.

It’s ok
Size: XX-Large Tall, Color: Carbon Heather
The collar area felt kind of tight for him. The shirt is nice and long, but not thick.

Carbon Carhartt
Size: XX-Large, Color: Carbon Heather
Classic Carhartt quality. Reasonably thick t shirt with a bit of stretch, but still sturdy and rugged. I put this on as soon as it arrived. I have nothing but a plethora of carhartt t's for the spring and summer. Added this color, Carbon Heather, to my collection. It looks plain cool. Almost like carbon fiber.

Perfect for casual or weekend wear whether working at home or relaxing
Size: XX-Large Tall, Color: Dusty Olive
Comfortable material. Durable, I ordered size 2xl tall and love that it’s a casual shirt that is long and even if I lift my arms up my belly isn’t exposed. Neckline isn’t too tight I usually prefer a v neck but this shirt is so big the neck doesn’t feel tight or constricting. Great value for its price. I will be wearing this at home and on the weekends for sure.

Classic look, great feel and great price.
Color: Black, Size: X-Large
Super comfy and casual, but classy enough that it can be worn out. I find this shirt extremely comfortable, it is a classic look and is very flattering. I wear a size 14 and the XL is loose but not baggy. It washes well, does not wrinkle if I get it out of the dryer and folded in appropriate time, and the material is a good weight for the cost of the shirt. I would likely buy again as this is a great summer staple.
