Fabric & care

Features

Breathable: Allows moisture vapor to escape, keeping the wearer dry.
Packable: Compresses down to almost nothing — takes up nearly no room in a pack.
Quick-Drying: Hydrophobic fibers wick moisture and dry fast if things get damp.
Easy-Fit: 1-inch elastic waistband and loose fold-over cuffs for a relaxed, no-fuss fit.

Fabric

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

What it's good for

Popular with backcountry skiers and backpackers who want a warm layer that packs down to nothing. Equally at home as a ski underlayer, backcountry sleep pants, or a cozy throw-in for any trip where space is tight.

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!

Shipping & returns

Ready to ship pieces ship in 1–3 business days. Made-to-order and custom pieces ship once they're sewn, currently in about 8–12 weeks. Orders that mix both ship together.

Free shipping on US orders over $130, and a flat $25 to most other countries.

Unworn ready-to-ship pieces can be returned within 30 days of shipping. Made-to-order returns have a 25% restocking fee, and custom returns 50%. Full returns policy

Made in the USA

Every Sambob piece is made in the USA. Our made-to-order and custom pieces are sewn by our team of three in Portland, Maine. Everything else is made by small sewing shops on the East Coast.

About 90% of our fabric is made in the USA, including all of our Alpha.

True Blue

I have a light/dark blue hoodie, Sambob, that I've worn for a couple of years, and I realized I needed to match it with the joggers. I currently have a set of down bibs I wear around the campground and post-race for my fall and winter trail races here in the Northeast, but I thought I could add another piece to make it truly cozy. Bingo! Love 'em.

I just wore them on a backpacking trip to sleep in on chilly nights. They were very warm and comfortable.

Skipping the base layers for a while

These are a great mid layer for really cold but they are also a great base layer for shoulder seasons. I’ve been leaving my merino at home for all my trips now that I have the joggers and the hoodie combo. So nice to sleep in them as well.

Very lightweight, warm and well constructed! I like how it has a tighter waistband and ankle cuffs but it still leaves plenty of room for your base layer!

Lite weight, toasty warm

Did a short backpack hike across Roan Mountains and used the joggers and pullover. I was thoroughly impressed with how toasty warm they kept me at night. Highly recommend!

Great As Layer

Got these to wear over wool thermals and under athletic shorts and finally under my outer insulated bibs. They perform as intended, the thinner weight avoiding bunching or restrictions due to a slightly fitted bib leg. Good loft is maintained, but for durability's sake, I wish I would have gotten a heavier weight (unavailable at the time).

I was in between sizes and I went with the small

I was in between sizes and I went with the small. The elastic in the waist is no joke and it took some wearing to make it more comfortable but I'm glad I went with the smaller size. Super comfy pants on cold mornings.

Runs Big

Really wanted to love these pants. My partner bought them for me for an upcoming thru hike. I got the curvy women's version in size XS. Unfortunately, they run very big. The waist goes up above my belly button by 3 inches. I have to roll the waist 3x to be able to get a good fit. The pants are super comfortable, but yeah just too big even in their smallest size. To preface- I'm 5'4, 130lbs, have a long torso/short legs and usually wear women's size XS or S. I am not an extremely small person by any means.

Hey! As with all orders, if things feel completely off in the sizing department, we're always happy to try to work something out. We could definitely do some adjustments on them or make a new pair if you're really unhappy with them. They do run big, but we can happily shorten the length or adjust the waistband length if requested. Thanks!
