Fabric

Polartec Alpha Direct 90. Our best selling, most versatile midlayer fabric. Read more about Alpha.

What it's good for

Popular with day hikers, runners, and thru-hikers. Warm enough alone, and pairs well with a wind or rain shell for extra warmth.

Care

This is a delicate fabric and must be treated as such! It will snag easily, so keep it away from Velcro, dog claws, and definitely don’t bushwhack in it. Machine wash cold and hang dry.

Can I give more stars?

Can I give more stars? Loved this piece of gear after the first time I wore it. It’s the perfect mid-layer. Super lightweight.

The ultimate layer

Got my alpha 90 hoodie for trail running and biking. This fall this thing has been my go-to. It packs down super light, and paired with a light shell layer, I have yet to get too hot or too cold. I’ve worn it from 50ish degrees to 30 degrees. On its own, air rips through and pulls heat away when moving, but warms up again when stopped, so for high output activities it’s the ultimate layer. Add a shell when windy or colder and it keeps me the perfect temp. Construction is quality and I really like the fit. True to size. Plus it’s super soft and cozy without being too warm, and the pink color is absolutely awesome. Thank you Sambob for making a really cool product that I absolutely love! It’s now my go-to for high output cool/cold weather activities and I’m sure I’ll get 4 season use out of it.

My through hike favourite!

I bought this to use on a 4 week through hike above the Artic circle in Scandinavia. Combined with a wind shirt it’s been outstanding. The flexibility, warmth and breathability it provides have been amazing. And it looks great too!

Excellent Alpha Hoodie!

This is one excellent Alpha 90 hoodie! The sizing is spot on. It is well-made and well-thought-out. It was also fun to pick some different coloring options for the hoodie. And yes, Alpha 90 is great on trail. It is super light, warm for the weight, and fits in my pack very well.

Great lightweight warmth for backing in Alaska

I bought a hoody and joggers for myself and a hoody for my daughter for backpacking in Alaska for a week. These pieces were really useful for warmth. We used the hoodies for an extra layer when stopping or when it cooled and I used the joggers for sleep pants with the hoody. When combined with a t-shirt, sun hoody and rain shell, all of which we were already carrying, these negated the need for a puffy. The material got a couple of pulls from bushes, but held up well for our use.

I Was Skeptical—Now I’m Sold!

I ordered a personalized Alpha 90 Hoodie and absolutely love how all the colors came together! This was my first Sambob order, but it definitely won’t be my last.

When I first received it, I’ll admit I was a little skeptical. It was so lightweight and almost see-through that I couldn’t imagine how it was actually going to keep me warm. I brought it along on our Canadian Rockies hiking trip, and I was seriously impressed! For something that weighs practically nothing, it kept me surprisingly warm and was perfect for layering on the trail. I love that I could stay warm without adding a bulky layer to my pack.

The quality, colors, and performance all exceeded my expectations. I’m already looking forward to ordering another one!

I truly love this hoodie

I truly love this hoodie. I have been wearing a Columbia fleece jacket for my fleece option while backpacking, and this has been quite the upgrade. It kept me warm at camp and on the windy peaks around Mt. Hood. It dries so quickly - I washed it in our hotel sink, squished the elastic parts with a towel, and it was dry by morning to wear home on the plane. I did get toasty in it a few times, but I'm going through perimenopause, so that explains a lot. I loved sleeping with this beside my pillow at night. It was perfect to curl up to- so soft!

Bringing back the 90s in my hot pink alpha 90!

My favorite active fleece by far! Just 1 tip though...

My favorite active fleece by far! Just one tip though, snip the corners of the logo at the bottom because it pulls on the threads. A good amount came loose from my sleeve when It would come into contact when I walk. Thankfully no hole. Still a 5 star for me Sam! <3

Incredible and Versatile Layer

These hoodies are the perfect layer for the SF Bay Area! I use mine while cycling, commuting, bikepacking, and more. They vent super well, but keep you warm when you need it. Even when I sweat a lot, it dries quickly and doesn't get that smelly. I think it's my new favorite camp sleepwear, too!

The best mid layer for ALL the things

I love my custom Alpha 90 & 120. They’re the first layer I grab for my daily wear and all my outdoor adventures. I’ve used them for ultra trail races with big weather swings and are cozy alone and super warm with a wind shell on top. Highly recommend!

Nice garment overall

Nice garment overall. Fwiw, I got the oatmeal color with teal trim in a custom order, the piping wasn’t that special and in the end I would have been happier to have gotten the basic oatmeal color quicker without waiting for the actual piping color. It would be great if it had a pocket that could hold a phone or wallet.

Exactly what I hoped

Exactly what I hoped for, and even lighter than I expected. This is my first alpha 90 shirt, and it does not disappoint. Thanks for offering an orange color option. I feel a bit better about hiking in hunting season wearing orange.

Loving this thing

I thought this would be an ultralight outdoor piece, but here I am wearing it everywhere. It feels like it will rip if you look at it wrong. And maybe it will. But it's this strange combo of airy and warm and light and comfortable. Can't get enough! My only complaint? No thumb loops.

Amazing product. Can’t wait to get on the trails with it
