FKT 5″
Rabbit
The Rabbit FKT 5″ is tailored specifically for the demands of the 'Fastest Known Time' crowd—runners who need technical storage, reliable chafe prevention, and long-mile durability on remote backcountry trails. Rabbit built this short to solve the gear-carrying conundrum without sacrificing the breezy feel of a standard 5-inch trail short. The standout feature of the FKT 5″ is its comprehensive waistband pocket layout. Similar to dedicated running belts, the waist features multiple stretch compartments alongside a rear zipper pocket. Reviewers note that this system easily secures energy gels, chews, headlamps, and even soft flasks flat against the center of gravity, minimizing vertical movement over rocky descents. The technical poly-spandex shell sheds light moisture and holds up well against pack rub. The trade-offs relate to complexity and price. With an intricate pocket structure, reinforced stitching, and a technical liner, the FKT 5″ feels slightly more substantial around the midsection than stripped-down road shorts. At roughly $75, it represents a focused investment for runners who plan to carry gear directly on their hips. **Highlights** - 5-inch inseam offering a versatile balance of mobility and thigh protection - Integrated multi-pocket waistband system designed for high-capacity trail storage - Rear zippered pocket locks down keys, identification, or nutrition securely - Technical stretch fabric handles deep strides and steep terrain - Comfortable, supportive liner built to resist long-haul chafing **Watch-outs** - Waistband is wider and bulkier than minimalist road alternatives - Can feel warm around the waist when all pockets are packed full

FKT Shorts
rabbit
The rabbit FKT Shorts stand as another variation of the brand's celebrated trail-running platform, designed specifically for long days where carrying capacity and soft-touch fabrics matter most. Built with an 87% polyester and 13% spandex blend, these shorts feature Rabbit’s signature soft fabric hand, eliminating the stiff, crinkly feel common in some technical synthetic shorts. Independent testing from outlets like Treeline Review awards these shorts top honors for their ability to manage gear without bouncing. The storage array wraps around the waist, offering dedicated spots for trash, nutrition, and key essentials. The liner is built with flat, non-abrasive seams that hold up across ultra-distance efforts, making them a regular fixture on marathon and 50K start lines. On the flip side, the FKT Shorts can feel slightly heavy if you only intend to use them for quick neighborhood loops where extra pockets are unnecessary. The soft fabric also holds slightly more moisture when saturated compared to ultra-crisp, perforated road shells. For backcountry trail runners who want all-day comfort and storage, they remain a top-tier performer. **Highlights** - 87% polyester and 13% spandex blend provides soft hand feel and four-way stretch - Wrap-around waist storage layout keeps fuel balanced and bounce-free - High-grade interior liner built to eliminate seams across high-friction areas - Broad size run spanning S through XL - Sturdy waistband construction that supports pocket weight without slipping **Watch-outs** - Overkill for track workouts or short runs where storage is not needed - Fabric retains slightly more water weight than paper-thin racing shells
