SierraLoft Insulated Jacket

Love this jacket! Great wind resistance and really good amount of warmth. This will work perfectly for cold hikes where I anticipate warming up a bit as it goes on while no overheating.

Love this jacket! Keeps you warm when you need it and packs down when you dont

This jacket fits like a glove on my 6’3”, 180 lb. frame. So often jackets like this are a bit short in body and sleeve length on taller than average guys, but this one is made just for us.
And the matte fabric makes this stand out as a quality product.

Excellent portable jacket. Wore it both nights at my last ultra and kept me nice and warm when temps dipped down into the 30s/40s.

I’ve tried a lot of lightweight jackets, and the KETL Sierra Loft has quickly become one of my go-to pieces.

The fit is spot on—athletic without feeling restrictive. It layers well over a tee or light hoodie, and unlike some packable jackets, it doesn’t feel overly tight in the shoulders or chest. Comfort is where it really stands out. The material is soft, flexible, and easy to wear all day, whether I’m traveling, walking a site, or just out running errands.

For a packable jacket, the warmth is impressive. It holds heat well without feeling bulky, making it ideal for cooler mornings and evenings or as a layering piece when temps drop further.

I already own several KETL pants and jackets, and this one fits right in with the lineup. Reliable, well-designed, and easy to pack—this has become one of my regular go-to jackets for both travel and everyday use.

Jacket works and fits great. As a 6'3 200lb guy it is a little difficult to find a jacket that isnt super bulky on me and this one does a great job.Ive worn it below freezing which was pushing the range it should be worn and up to 60 with just a t shirt underneath. Performs great as a do it all jacket, my new favorite. Only complaint is it isnt very breathable, but would likely use either a heavier jacket or a windbreaker with layers under it for active stuff anyways.

I purchased this jacket for my early spring cruise up the Norwegian coast. Temps in the 20s- 40s with windchill in the low teens. I wanted a packable layer to use with merino base and pullovers. It worked great. Good wind protection, a decent amount of insulation and the hood came in handy. Suggestions - interior pocket would be nice, something to tighten the hood,

I LOVE this jacket! It's very well-made, comfortable, and has kept me warm in 30-degree, windy weather. This is one of my first KETL purchases, and I have definitely found a new favorite brand. Keep up the great work!

İt is soft and comfy to wear a little bigger in size but ok)

This is a great fitting and even better looking jacket. I wear it as an everyday over business casual clothes, but I am also planning on packing/wearing it on some long hikes, by itself and under another shell. Super comfortable, high quality. Very happy with this purchase, one of my fave pieces of gear.

Love the jacket! Very light but holds up well against the cold. Daily jacket now

Jacket is soft and lightweight. I really like how it can break down for travel. The neck area does somewhat dig into my chin when zipped all the way up, but I hardly ever do zip it all the way up so no biggie. For how lightweight the jacket feels it's comfortably warm. So far, I highly approve.

Lightweight, easily packs, amazing feel, great materials…checks all the boxes.

This is my third jacket from KETL. Previously bought the rain jacket shell. Love this new jacket! Perfect fit, comfortable, great quality. Exactly what I was looking for in a lightweight winter jacket.

It’s thinner than I expected it to be and that caught me off guard at first but it’s been really nice. The fit is exceptional and it’s remarkably comfortable to wear.

It’s warm and the sizing is great. I’ve worn it with a thermal, FOX Baseframe Pro and a jersey underneath with no restriction of movement. It’s a good fit for the advertised temp ranges.

Excellent warm but lightweight jacket. Quality is exactly what is expected from ketl..10/10
