TANTRUMS Launches High-Performance Hydration Packs Built for Endless Miles

December 2, 2025

New Roam 11 and redesigned Crest 6 vests built for long miles and harder trails

Pasadena, CA (December 2, 2025) /OUTDOOR SPORTSWIRE/ — TANTRUMS, the performance running brand redefining trail gear, introduces the Roam 11 and a redesigned Crest 6 — made for long days, steep climbs, and the kind of running that leaves a mark.

Known for combining modern design with technical precision, TANTRUMS has become a familiar sight on the backs of elite athletes at some of the toughest races in the world. With the Roam 11, the brand pushes further — delivering an 11L system built for 200-milers, big days in the mountains, and those long runs that test what you’ve got left.

Both the Roam 11 and Crest 6 feature TANTRUMS’ proprietary backbone construction, a new chassis that blends monofilaments with spacer mesh to deliver stability and comfort — proven through a podium finish at Cocodona 250 and a win at Mammoth 200.

“The Roam 11 and Crest 6 are built for the miles you remember — and the ones you try to forget,” says Adam Copeland, Founder of TANTRUMS. “They move with you, not against you.”

TANTRUMS Roam 11 – $245 MSRP

Engineered for big days and relentless terrain.

Key Features

• 11L Storage, Zero Bounce: Race-ready capacity that stays secure — no sag, no shift.

TANTRUMS Crest 6 – $225 MSRP

Lightweight, breathable, and built to move. The Crest 6 evolves with a Cordura-infused textile for improved durability while maintaining its ultra-light, highly breathable feel. A refined sternum fit system allows for faster on-and-off transitions. Subtle refinements improve access and longevity without changing the streamlined fit runners already love. The result is a fast, balanced pack that disappears on the run — the Crest 6 keeps focus on the miles ahead.

Key Features

• Optimized Fit & Stability: Hugs the body without restricting movement; eliminates bounce at speed.
• Hydration Versatility: Carries a 1.5L rear reservoir and 2 × 600mL Hydrapak WMX soft flasks up front.
• Breathable, Lightweight Build: Ultra-light mesh with targeted ventilation zones for maximum airflow (75% Nylon / 25% Mesh).
• Intuitive Pocket Layout: Easy-access stash pockets for gels, bottles, and gear on the run.
• Minimalist Design, Maximum Function: Purpose-built features within a fast, low-distraction profile (Weight: 135g in size Medium).
• Trekking Pole Carry: Hidden loops and elastic straps securely attach poles; Salomon Quiver compatible.

The new Roam 11 and a redesigned Crest 6 will be available Spring ‘26 at select retailers and www.tantrums.run.
