These Alpha 90 Joggers are jogger-style fleece pants made from Polartec® Alpha Direct at 90 gsm — Sambob's best-selling, most versatile Alpha weight. Warm enough to wear on its own and still packable enough to disappear into a bag, they're a favorite with backcountry skiers and backpackers who want one warm layer that does double duty. Th

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. 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.
