Keep your Jambys soft and true to size with a simple wash routine. Learn the right temperature, cycle, and drying method to prevent pilling and shrinkage.
Quick answer
Wash your jambys-dc85f65cf5ba9091c011c3b8-2945741">Jambys in cold water on a gentle cycle with like colors, then air dry or tumble dry low. This prevents shrinkage and friction that causes pilling, keeping the modal-spandex fabric soft and true to size.
Why modal-spandex needs a gentler routine
Jambys and Long Jambys are made from a 95% modal and 5% spandex blend. Modal is a plant-based fiber that feels incredibly soft, but it can shrink or pill if exposed to high heat or rough agitation. Spandex adds stretch; heat breaks it down over time, leading to a looser fit. A gentle wash routine protects both fibers, so your loungewear stays comfortable for years.
Sort and prepare before washing
Separate your Jambys from heavy items like jeans or towels. Zippers, buttons, and rough fabrics can snag the soft modal surface and cause pilling. Turn your Jambys inside out to protect the outer surface from friction. If you wear Long Jambys with underwear or Jambys underneath, that's fine—just make sure all items are similarly lightweight.
Choose the right detergent and load size
Use a mild, liquid detergent free of bleach and fabric softener. Fabric softener can coat the modal fibers and reduce breathability, while bleach weakens spandex. Avoid overloading the machine; Jambys need room to move freely without rubbing against each other. A small load with a few similar items is ideal.
Drying: air dry or low heat only
The safest way to dry Jambys is to lay them flat or hang them to air dry. If you must use a dryer, choose the lowest heat setting and remove them while slightly damp. High heat is the main cause of shrinkage and can also set in wrinkles. Never dry on high or leave them in a hot dryer after the cycle ends.
Step-by-step Jambys washing routine
- Turn inside out and sort: Turn your Jambys inside out and wash them only with other lightweight, soft items. Avoid mixing with jeans, towels, or anything with zippers. Checkpoint: If you feel rough textures, keep them out of the load.
- Use cold water and gentle cycle: Set your washing machine to cold water and the gentlest cycle available, such as delicate or hand-wash. Add a mild liquid detergent without bleach or fabric softener. Mistake to avoid: Hot or warm water can shrink modal and damage spandex.
- Air dry or tumble low: Lay Jambys flat to air dry, or tumble dry on low heat and remove promptly. Never hang them by the waistband, which can stretch them out. Checkpoint: If you must use a dryer, stop it while they are still slightly damp.
- Store folded, not hung: Once completely dry, fold your Jambys and store them in a drawer. Hanging can cause the fabric to stretch over time. Final step: Enjoy your soft, well-fitting Jambys.
Product care facts
- Navy Long Jambys: Navy Long Jambys are made from 95% Modal and 5% Spandex. Modal is prone to shrinkage with heat, and spandex loses stretch, so cold washing and low drying are essential.
- Black Long Jambys: Black Long Jambys share the same 95% Modal, 5% Spandex blend. The same care routine applies to all Long Jambys regardless of color, so you can wash them together.
- Cerulean Jambys: Cerulean Jambys are made from a signature fabric that feels like silk and has stretch. The silky finish can pill if washed with rough fabrics, so separate them from heavy items.
