I have a back problem and even with a light duty chit my snco said he doesnt care and I still have to hike with full gear. Can they do that or any suggestions. Thanks!

Shirts with a high polyester mix are really the best. Cheap, breathable and easy to clean. Target sells some under the C9 brand for $10
Avoid cotton. They take a long time to dry after getting wet and odors stay on on damp cotton.
Swim trunks make good low tech hiking pants. Dries quick and breathable.
