The Billabong Boundary is a men’s half-zip fleece designed for outdoor adventures and everyday layering. It delivers lightweight warmth and breathability in a simple, classic silhouette that works as a midlayer on cooler days or as a standalone piece when the temperature’s mild.
Made from a blend of 70% recycled polyester and 30% polyester, this fleece helps give discarded PET bottles a second life while still feeling soft against the skin. The regular fit provides room for movement without feeling bulky, and the elastic drawcord at the waist lets you fine-tune the silhouette to keep drafts out. A zippered chest pocket keeps small essentials secure, and the 4-way stretch construction follows your motions whether you’re scrambling over rocks or reaching for your pack.
“4-way stretch” means the fabric can stretch both side-to-side and lengthwise, so it moves with you rather than restricting you. That added flexibility helps maintain your range of motion during hikes or any activity where you need to bend, reach or twist without feeling held back by your clothes.
