Departing on the ZZZZZX departure coming through 10;000 feet we accelerated.  When we were handed off to Center from previous Controller we were advised 'Normal speed' and realized we had not maintained 250 knots; but had accelerated to 280 knots. ATC made no other comment.The Captain had been on an LOA for 6 months plus 3 months re-qualification training delay; I had been off for 3 weeks because of COVID-19 vaccination sequence removal; with other family issues at home.  The flight was an early morning departure with early commute (drive).Suggestion - More personal detail to SOP on SIDS and programming of FMS.
On climb from 10;000 feet to Flight Level; accelerated over 250 knots climb restriction. Was given ' normal speed' by Center Control after handoff. Looked at the airspeed and it was 280 knots.My first (after Re-qualification and OE) flight sequence back from 9 month leave. The First Officer was back from a 3 week absence himself. I even thought about it prior to takeoff; and noticed a 250 knot restriction was not programmed in the FMS; but assumed he would control the speed manually. I did not voice my thoughts; but should have. I became fixed on other issues; getting off the gate smoothly; taxing safely; ensuring the performances numbers were correct. Remembering and doing the after takeoff flows; check lists. All things that were once second nature; but distracted me due to the long absence from flying.Simply stating to my co-pilot that I haven't flown in 9 months isn't enough. I needed to be on my game; and not let a simple speed restriction escape me. My own technique is to program the airspeed in VNAV so such a mistake is less likely. Every pilot has their own techniques; but I should have voiced mine; so at least the issue would have been addressed and in our minds.
Air Carrier flight crew reported a speed deviation occurred during the SID procedure and stated that a prolonged period of time off for both pilots was the main cause.
