Oso Supply Co Crux Large Roll-Down Bouldering Chalk Bucket Mineral Blue/Red/White — Recycled Polyester, Magnetic Closure

The Oso Supply Co Crux Large Roll Down Bouldering Chalk Bucket is a freestanding, roll-top chalk bucket built from recycled polyester with a magnetic closure, zippered storage pocket, and roomy opening for hands‑on chalking during bouldering sessions.

When you need a dependable base at the crag or in the gym, the Crux Chalk Bucket combines practical features and bold styling so your chalk stays contained and your accessories stay organized. Handcrafted from recycled materials, this bag balances durability with a lightweight 7‑ounce build and a compact footprint (10"H x 7"W x 5"D) that’s designed specifically for bouldering—no waist belt required.

How does the roll-top and magnetic closure keep chalk contained?

The roll-down top seals the bag’s large mouth quickly, and built-in magnets plus quick-release clips lock the closure in place. That dual system minimizes accidental spillage when carrying or moving the bucket between problems.

• magnetic roll-top snaps shut to reduce dust escape
• quick-release clips secure the roll for transport
• wide opening still allows two-handed chalk access before closing

What storage options are included for small gear and valuables?

The Crux includes an interior zippered pocket and an external mesh pouch to keep small items separate and reachable. Stash your phone, keys, wallet, tape, or a compact brush without cluttering the main chalk space.

• zippered pocket sized for phone and keys
• external mesh pouch for brushes and tape
• spacious interior keeps chalk separate from valuables

Will this bucket hold up to regular use outdoors and in the gym?

Built from recycled polyester and reinforced stitching, the Crux is made to withstand frequent handling and varied conditions. The materials and construction deliver longevity while keeping the bag lightweight for easy moving between problems and routes.

• durable recycled polyester body resists abrasion
• heavy‑duty stitching at stress points for longer life
• weather‑tolerant materials suitable for indoor and outdoor climbing

How practical is the size and shape for bouldering sessions?

The bucket’s freestanding form and oversized mouth let climbers dip both hands in comfortably for fast re‑chalk between attempts. At 10" high and a 7" by 5" base, it strikes a balance between roomy interior capacity and a compact footprint that won’t dominate your landing zone.

• extra‑large opening for easy two‑hand access
• compact base that stays out of the fall zone while remaining stable
• lightweight 7‑ounce construction for simple transport

Who is this for: The Oso Supply Co Crux Chalk Bucket suits climbers who want a purpose-built, freestanding chalk solution for bouldering—especially those who appreciate organized storage, quick access, and sustainable materials. It’s ideal for gym regulars and outdoor boulderers who need a durable, lightweight bucket with tidy storage for small essentials, but it’s not designed to be worn on the body.
