There is no איסור of שביתת כלים by גיגית ונר, etc., because presumably he is מפקיר them and there is no other viable option; this does not apply to שביתת בהמתו when renting to a נכרי.
There, where the meat is on the coals - התם בבשרא אגומרי
Summary:

And he should not lend him, etc. unless he will reach his house - ולא ישאילנו כולי אלא כדי שיגיע לביתו
Summary:
We are not discussing utensils for it is always אסור to lend them to a נכרי (according to ב"ש) because of שביתת כלים. We are discussing lending clothes, which one is forbidden if the נכרי does not reach his house before שבת, because he may be mistaken for a שליח of the ישראל to carry on שבת.
