Endurance Model Perfect for Ultramarathons
For All Ultra-Trail Runners
FOR ULTRA TRAIL
The RUSH11R, developed for ultra-trail runners, has been completely renewed. Based on user feedback, the carrying comfort and usability have been significantly updated. The high center of gravity design and adjustable harness allow for stress-free use during long races.
HIGH CENTER OF GRAVITY
The high center of gravity design, which optimizes the center of gravity between the backpack and the wearer, achieves an excellent weight balance. This reduces the sensation of carrying a load and alleviates fatigue.
Fits Your Back Too
SHOULDER ADJUSTERS
The shoulder harness is designed to fit runners of various body types. It can be easily and infinitely adjusted with Velcro. Please use the stitching as a guide for adjustment.
SIDE ADJUSTERS
The side adjusters feature a 6-point bungee cord system, providing a secure, "sucking" fit and excellent breathability. The drawcord at the waist can be pulled with one hand, allowing for easy adjustment even while running.
CHEST STRAP & PGW TWIST LOCK
The chest strap is made of a flexible material for a soft feel against the skin. The unique "PGW TWIST LOCK" buckle was developed for easy operation even when fatigued. We also focused on lightness and durability. With practice, it can be operated with one hand.
Intuitive Pocket Layout
POCKET LAYOUT
The pocket layout has been improved based on user feedback. It allows for stress-free operation while running and optimal packing according to frequency of use.
BOTTLE POCKETS
Optimized for soft flasks up to 600ml and 500ml PET bottles. The drawcord prevents them from falling out. Includes an emergency whistle.
SNACK POCKETS
The lower pockets with drawcords are suitable for storing gels and energy bars. The capacity has been increased and accessibility improved compared to the previous model.
SIDE POCKETS
Equipped with a zipper pocket on the right side and a flap pocket on the left. Ideal for seldom-used valuables, portable cups, and trash.
MAIN ACCESS
The main access uses a top-entry system, designed for easy retrieval of items. It's designed for easy access in various situations.
TOP POCKET
The top pocket is designed to store a headlamp. With practice, it can be accessed even while wearing the pack. Includes a key hook.
BOTTOM POCKET
Wind shells and gloves can be stored in the pocket at the bottom of the main body. The large opening makes it easy to put items in, and the design makes it difficult for items to fall out even during intense movement.
STOCKHOLDERS
Trekking poles are secured by threading them through holders on both sides of the drawcord. The included bungee cord can be used to attach them in your preferred location. The separately sold RUSH Pole Holder can also be attached.
HYDRATION POCKET
There's a pocket on the back for a hydration pack, and the hose can be routed over the shoulder. Placing a thin shell jacket or rain pants inside provides cushioning against the items in the back, making it more comfortable to carry.
DESIGNER'S VOICE
The RUSH series, born in 2015, has constantly evolved by reflecting user feedback. Looking back, I'm amazed at how we've created 40 models in just 11 years – I can't help but think, "I'm a development addict." However, backpacks used in the demanding sport of trail running are truly interesting and never boring as a design theme. For example, how can we minimize "physical stress" such as shoulder pain and "mental stress" from inconvenience, and design it stylishly and rationally? This is the challenge. To solve these issues, we've listened to passionate feedback from many runners at races and events and have gone through countless prototypes and tests. This is very painstaking and persistent work. It's not glamorous, but this is PAAGOWORKS' development style.
This new RUSH has also undergone significant evolution with the involvement of many runners. We want RUSH to be the ideal tool created by all runners. This sentiment is embodied in the phrase "Designed by the Runners." If you see a RUSH on the trail, I hope you'll remember these words.
