Serious female trail runners, this Deuter Traick 9 SL vest is designed specifically for your anatomy and running needs! The 9-liter capacity gives you enough space for hydration, nutrition, and essential gear without being bulky or restrictive. The close-fitting design with breathable stretch material hugs your upper body comfortably without bouncing, even during technical descents. The elastic chest strap system adjusts quickly and stays secure while allowing full breathing capacity at any intensity level. There are two pockets for soft flasks on the shoulder straps plus two zippered pockets for easy access to gels, phone, or other small items while running. The separate hydration bladder compartment holds up to 2 liters and has quick refill access. The modular elastic cords let you attach additional gear like jackets or layers securely. The pole attachment system is genius - you can stow your trekking poles quickly and access them easily when terrain gets steep. The women-specific fit means no awkward chafing or pressure points, and the overall design keeps weight distributed evenly so you can focus on your run rather than your gear. Whether you're training for ultras or just enjoying long trail runs, this vest provides the comfort and functionality that serious runners appreciate.
