Review on 🏃 TRIWONDER Lightweight Deluxe Running Race Hydration Vest Backpack Water Pack for Marathoners by Luke Liu

I wanted this to be a day pack for my son's scout camp where it would wear all day in the heat, humidity and rain and take it anywhere. I wanted more pocket access so I didn't have to take them off to get something. I'm happy, especially since there's a zippered side pocket on one strap, long enough for my long, thin Samsung Note 8 phone. This bag and the "large" main compartment on the back are waterproof. This is enough as many other pockets are made from quality stretch mesh, which is a worthy compromise. Tiny top pockets can hold keys, hair ties, gu packs, lip balm, or bug/post bite repellent packs. I was able to easily access the zip on the hip belt and they are roomy and have a sleeve at the bottom too. It stays in place even after several modifications. However the overall fit is SMALL and I'm a 5'2" female with a 38B above but broad shoulders. The entire backpack and hand straps have elastic piping to make the fit slightly stretchy but snug and essentially the Edges gathered so they are smaller than the compartment's dimensions. I ended up loosening the fit around the lower torso by trimming the outer elastic in 4 places where the pouch will not damage, on either side of the "thigh" -Belt that actually hits my lower ribs from the cuts is still well above the pelvic bones but cutting the piping allowed the mesh to stretch properly Insulation sleeve to prevent condensation from hydration chamber (not included , but we have a lot) other content. However, when the water chamber is full, there is hardly room for a foldable jacket. The only bad design is the appliqués on the undert eil, which apparently allows you to lengthen the lower part of the body, sewn in such a way that this is not allowed; and while the perforated mesh fabric on the back is form-fitting and helps keep it in place and breathable, I would have liked some stiffness or structure. If not worn, everything flops; It is best to hang on a hook so that some items do not fall out of the open compartments.
