Pack straps chew through ordinary fleece. This Polartec 100 crewneck has stretch nylon where a ruck rubs: the shoulders, the forearms and the chest.
“Just as described - generous sizing, lightweight and easily packable, but super warm. Washes very well - no sign of pilling or bobbling, even after numerous washes…comes up like new.”
Finally: Nylon where the straps sit.
Stretch-nylon panels cover the top of both shoulders, so the straps rub nylon, not fleece. Ruck all day and the shoulders don’t pill or thin out.

Finally: Abrasion-resistant forearms.
The outer forearms take the hits when you push through brush or brace on a rock. Nylon runs down to the cuffs there, and it stretches with you.
“I've had the previous model for a year now. Great design, craftsmanship. The patch is a bit worn but everything else is still like new.”

Finally: Fleece that breathes and dries fast.
Polartec 100 microfleece lets heat and sweat out while you move and dries fast when you stop. Throw a shell over it at the halt and keep going.
“This fleece crewneck offers exceptional comfort. With its spacious pockets, it provides plenty of storage while on the move. Depending on the weather, it can be worn on its own or layered as a warm mid-layer.”

Finally: A chest pocket you can reach with a pack on.
A zip pocket in the nylon chest panel sits above the hip belt and between the straps, so your phone or map is always in reach.
“Possibly the best fleece I've had, warm, light, practical (pockets in the right places), excellent quality.”

Finally: Built to take a beating.
Nylon where fleece wears out first, Polartec everywhere else, and every seam cut and sewn in Ukraine. It’s made for the next hundred rucks, not one.
“Can tell from the feel it will last forever. Super nice and warm.”
Harrison P. · review of our Defender Polartec 1/4 Zip FleeceLight enough to move in, tough where the pack sits, dry by the time you stop. It's the layer you'll reach for every time the ruck comes out. Cut and sewn in Ukraine, from American-made Polartec.
Before we sold a single one, our team wore it for six days and 55 km off-trail through Kluane National Park, with full packs: no trail, freezing nights, snow on the passes, grizzly country.
“I wore the crew neck literally every day… really, really heavy bush… having the abrasion pad… you can just be confident it's not going to tear up the fleece.”
Luke, on our team, after the Yukon trek

Lightweight, abrasion-resistant microfleece crewneck
Regular fit. Size as you would a sweater you layer over a base layer.
“Incredibly warm, very well made like the rest of the gear. Thanks again!”
