Participant Enrollment & Informed Consent Congratulations! You’ve been selected to participate in the Yomisma REST Study™. The REST Study is a 30-day consumer sleepwear evaluation designed to help Yomisma better understand participants’ experiences wearing our sleepwear, including sleep comfort, temperature regulation, nighttime sweating or clamminess, overall sleep experience and other attributes of the garment.

Please use the same email address you used when applying for the REST Study.

Please double-check your shipping address before submitting. Your Yomisma sleep shirt will be shipped to this address.

Several REST Study surveys will be sent by email each week. During the week, these will include just a few quick questions about the previous night’s sleep, with a longer survey sent over the weekend. We ask that you complete the morning surveys as soon as possible after waking, while your sleep experience is still fresh in your mind.

About Your Participation

The REST Study is a 30-day consumer product evaluation.

By enrolling, you are agreeing to make a good-faith effort to participate for the full 30-day evaluation period and complete the requested study activities to the best of your ability.

During the study, participants will be asked to:

• Wear their Yomisma sleep shirt on designated study nights according to the study schedule.
• Complete a brief morning self-report survey four times per week on nights when they wear the Yomisma sleep shirt.
• Complete a broader survey at the end of each week.
• If participating with a compatible wearable device, refrain from reviewing sleep data until after completing the week’s self-reporting. At the end of each week, you will be asked to review your wearable and enter designated sleep metrics into the weekly survey.

We ask participants not to review their wearable sleep data during the week because seeing a device-generated sleep score or other sleep metrics could influence how they subsequently evaluate their own sleep experience.

We want your morning responses to reflect how you genuinely felt and slept, independent of what your wearable reports.

Please answer all study questions honestly and to the best of your ability. There are no “right” or “wrong” answers.  Your genuine experience — whether positive, neutral, mixed or negative — is what is valuable to this evaluation.

The Yomisma sleep shirt being evaluated in the REST Study is made with Yomisma’s proprietary three-fiber textile, developed specifically for sleepwear. The textile combines three functional fiber components selected for their different textile properties. The purpose of the REST Study is to better understand how women experience the finished garment during real-world use, including their perceptions of temperature and thermal comfort, moisture and clamminess, overall comfort and sleep experience. Because your individual experience is what we are evaluating, we do not want to tell you how you “should” feel while wearing the garment. There are no expected answers, and your experience may be positive, neutral, mixed or negative. The REST Study does not guarantee that the sleep shirt will produce any particular result for an individual participant.

The sleep shirt is being provided specifically for your participation in the evaluation. Your garment can be washed and dry on delicate - low temperature setting. Participants who successfully complete the 30-day study and required study activities will also receive an additional complimentary Yomisma item by mail as a thank-you for completing the evaluation.

Participation in the REST Study is voluntary. I may stop participating at any time and contact Yomisma if I wish to withdraw. I understand that the Yomisma sleep shirt is being provided specifically for participation in the REST Study. If I withdraw before completing the evaluation, Yomisma may require me to return the sleep shirt. If requested, Yomisma will provide return instructions and a prepaid method of return. The Yomisma sleep shirt is made primarily from lyocell and viscose, widely used cellulosic textile fibers made from plant-derived cellulose, commonly sourced from wood pulp. The textile also incorporates three functional fiber components derived from naturally occurring or plant-derived source materials. Yomisma is not aware of any reason to expect unusual skin sensitivity from normal use. However, individual sensitivities to any textile can vary. If I experience unexpected or persistent skin irritation or discomfort, I should discontinue use and let the Yomisma study team know. If I experience symptoms that concern me or may require medical attention, I should contact an appropriate healthcare professional. Participants who successfully complete the 30-day study and required study activities will receive an additional complimentary Yomisma item by mail as a thank-you for completing the evaluation.

During the REST Study, Yomisma may collect my contact and shipping information, demographic and eligibility information previously provided during the application process, study survey responses, information about my sleep and experience wearing the garment, designated wearable metrics and study-related communications. Yomisma may use this information to administer and analyze the REST Study, evaluate and improve its products, conduct research and development, and develop aggregated or de-identified findings. Whenever reasonably possible, study results used for analysis or reporting will be aggregated or de-identified so individual participants are not publicly identified. Yomisma will not publicly identify me by name, photograph, video, social-media handle or other personally identifying information in connection with my study responses without separate permission. Yomisma will take reasonable measures to protect participant information; however, no electronic storage or transmission system can be guaranteed to be completely secure. Yomisma will retain identifiable participant and study data for up to 12 months following the conclusion of the REST Study. After that period, personally identifying study information will be deleted or de-identified where reasonably practicable, except for information Yomisma is required to retain for legal, regulatory, accounting or legitimate business-record purposes. Yomisma may use accurate aggregated or de-identified findings from the REST Study without separately identifying me.

Yomisma may use excerpts or quotations from my study survey responses in an anonymous or de-identified manner, provided the quotation is presented accurately and does not identify me. Yomisma may also identify something I voluntarily write in a study survey that it would like to use as an attributed quote or testimonial. Participation in the REST Study does not automatically give Yomisma permission to attribute an individual quote, survey response or testimonial to me. If Yomisma wishes to use my name, photograph, social-media handle or other identifying information in connection with a statement, Yomisma will request my permission separately. I may accept or decline such a request, and my decision will not affect my participation, completion status or any benefit associated with completing the study. Yomisma does not require a positive testimonial, review or particular statement as a condition of participation. I am free to express my honest opinions about Yomisma and my experience. To help preserve study integrity and reduce the possibility of participants influencing one another, Yomisma asks participants, when reasonably possible, to wait until the 30-day evaluation concludes before publicly reviewing or discussing the sleepwear’s performance or study results. This is a request for study integrity, not a prohibition on an honest review or opinion. If I publicly post, review, recommend or endorse Yomisma sleepwear, I understand that I should clearly disclose my connection to the REST Study and the complimentary product when that relationship would not otherwise be apparent. Example disclosure: “I received this complimentary sleep shirt as a participant in the Yomisma REST Study.”

Individual experiences vary. Yomisma does not promise or guarantee that wearing the sleepwear will improve my sleep, reduce night sweats, change my body temperature, improve wearable-device measurements or produce any particular health or wellness result. The REST Study is intended to evaluate participant experiences and collect information about the product. Participation should not be interpreted as medical treatment or a guarantee of product performance.
